About data tables

A customer 360 database is built using standard outputs of the Stitch process that provide a unified view of customer data, including customer profile and interaction records that are linked together by the Amperity ID, organized, merged, and ready for use in segmentation.

About the data model

The data model represents the “out-of-the-box” tables that are available to every tenant. (AmpIQ tables are available only to tenants that have added AmpIQ to Amperity and have completed the process of enabling predictive attributes.)

Important

This data model represents the starting point for all tenants. It is common for a tenant to have additional tables that support specific data requirements and workflows.

Data model diagram

The following diagram shows the data model for core tables in Amperity. Color coded sections identify which groups of tables are associated with customer profiles, interactions records, Stitch QA, and AmpIQ.

There are four groups of tables in this diagram:

Group name	Description
Customer records	A customer profile is a collection of attributes that are associated with a single unique individual in the customer 360 database. The total number of customer profiles is equal to the total number of rows in the Customer 360 data table. This total correlates strongly, but not exactly, to the total number of Amperity IDs assigned to unique individuals in the same data set. The Customer_360 table represents your primary set of customer profiles and is the most common starting point for building segments. Each customer profile is built using a combination of the Merged_Customers, Customer_Attributes, Unified_Customer, and Unified_Coalesced tables.
Interaction records	An interaction record is a row in a customer data table that contains information about customer behavior, such as purchases (items bought, items returned, costs of items, etc.) and preferences (brands, products, cart adds, etc.). Interaction records rely on a series of tables: Transaction_Attributes, Transaction_Attributes_Extended, Unified_Itemized_Transactions, Unified_Transactions, and Unified_Product_Catalog. Each Amperity ID in the Customer_360 table can be associated to many rows in the Unified_Transactions table, and then each Amperity ID in the Unified_Transactions can be associated to many rows in the Unified_Itemized_Transactions table. Each Amperity ID in the Customer 360 table is associated to one Amperity ID in the Transaction_Attributes table. Note The Transaction_Attributes table has an associated “extended” table that captures additional attributes when data sources provide to Amperity the data required to complete the calculations for the attributes. It exists as a separate table in the customer 360 database, but should be viewed as a subset of transactions attributes data.
Stitch results	Stitch QA is a process that monitors the quality of Stitch results. Stitch QA has two components: a database and a set of queries. The results of these queries are analyzed to help identify values that should be labeled or blocklisted and discover situations where the results of the Stitch process require tuning to match your tenant’s data set. Stitch QA activities rely on a series of tables: Unified_Coalesced, Unified_Scores, Detailed_Examples, Unified_Preprocessed_Raw, Unified_Changes_Clusters, and Unified_Changes_PKS. These tables are the basis for the Stitch QA process ; the use of any specific table will vary from tenant to tenant. Together they provide visibility into how Amperity grouped (or did not group) individual customer records to a single Amperity ID.
AmpIQ	AmpIQ enables customer-centric marketing campaigns. Use segment insights to build high-value segments. Use those segments to add audiences to campaigns. Build campaigns that send those audiences to any combination of downstream marketing workflows. AmpIQ tables are enabled for users of AmpIQ and are the results of the configuration and tuning of Amperity for predictive analytics. These tables rely on the Merged_Customers, Unified_Itemized_Transactions, and Unified_Transactions tables for predictions, but there is not a 1:1 or 1:many relationship between those three tables and AmpIQ tables. The Predicted_CLV_Attributes table contains one row per Amperity ID, whereas the Predicted_Affinity table contains many rows per Amperity ID. The Campaign_Recipients table contains a history of all campaigns that have been sent from Amperity. This table is updated on a recurring basis and may be used like any other table in your customer 360 database.

Data model indicators

This diagram uses the following indicators to highlight relationships between tables and to call out fields that are primary keys, establish links between tables, or associate this table back to a domain table in the Sources page:

Name	Description
1:1, 1:many	Indicates that this table has a 1:1 or 1:many relationship with another table. For most tables, this relationship is based on the Amperity ID.
Many:1	Indicates that this table has a many:1 relationship with another table. For most tables, this relationship is based on the Amperity ID.
Primary key	Indicates this column is the primary key for this table.
Linking key	Indicates this column links customer records, such as those associated with a customer key or a foreign key that were defined as part of a feed or custom domain table from the Sources page.
Data source	Indicates this column is associated to an original customer data source in the Sources page, with the value of this field being the name of that data source.

All_Opted_In_Emails

The All_Opted_In_Emails table contains all opted-in email addresses (and associated Amperity IDs). This table is built from the Email_Opt_Status table, after which it can be extended to support brands, region, email program, and language preferences.

Warning

The All_Opted_In_Emails table is not unique by Amperity ID and should not be used within the Segment Editor.

The All_Opted_In_Emails table contains the same columns as the Email_Opt_Status table. Unlike the Email_Opt_Status table, the All_Opted_In_Emails table should be made available to the Segment Editor. This ensures that the email attribute in this table is available to campaigns. (Choose the email attribute from the All_Opted_In_Emails table from the Edit Attributes menu.)

Campaign_Recipients

The Campaign_Recipients table contains a list of Amperity IDs associated with any campaign (i.e., sub-audiences) that were sent from Amperity. Each campaign is associated with the segment used to generate the list of recipients, the control and recipient groups (including sub-audiences) used for the campaign, its launch date, and all destinations to which the campaign was sent.

The Campaign_Recipients table is generated by Amperity, and then made available as a standard database table. Use this table to access campaign attributes, perform historical campaign analysis, and to build segments and multi-stage campaigns that use the results of previous campaigns.

Important

Data in the Campaign_Recipients table is updated after the next database run. If your database is configured to run once per day then data in the Campaign_Recipients table will be available on a 1-day delayed rolling basis.

Note

See Campaign_Recipients for more information about how this table is built and maintained within Amperity.

The Campaign_Recipients table contains the following columns:

Column Name	Data type	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000

Customer_360

The Customer_360 table is the unified view of the customer across all points of engagement, including attributes that cross systems. This table does not exist by default and must be created within the customer 360 database. Each row represent a complete record for a unique individual, including their Amperity ID, merged PII data, and summary attributes.

Note

See Customer360 for more information about how this table is built and maintained within the customer 360 database.

Note

The columns that appear in the Customer_360 table will vary, depending on the SQL statement used to add columns to the table. The set of columns must include the Amperity ID and should include columns that contain profile (PII) data, along with columns that contain summary attributes for interaction records.

Detailed_Examples

The Detailed_Examples table contains detailed examples of Stitch results. Use these examples to help identify which features lead to scores with the biggest effect on overall Stitch results, including how they are associated with various combinations of fields that contain PII data.

Note

The Detailed_Examples table is a subset of the Unified_Scores table.

The Detailed_Examples table contains the following columns, as its starting point. This table is typically updated to add more pairs, enable use for blocklisted values, and to support additional tenant-specific use cases.

given_name_a given_name_b	String	The first name that is associated with an individual customer record.
match_category	String	A match category is a classifier that is applied by Amperity to an individual record-pair within a cluster of record-pairs. The match category is the result of this classification. Match Category Description Exact Amperity has the highest confidence that these records represent the same person because all profile data exactly matches. Excellent Amperity has near perfect confidence that these records belong to the same person, despite select types of profile data not matching. High Using deductive reasoning, Amperity has very high confidence that these records match, despite some profile data not matching. Moderate Amperity has moderate confidence that these records match, due to weak or fuzzy matches between highly unique customer attributes (email, phone, address). Weak Amperity lacks confidence, but if asked to guess, Amperity would assert these records do belong to the same individual, because they match on non-unique customer attributes (name, state, zip code). No conflict Amperity has high confidence that these records do NOT match, because core profile data is in conflict. Also in: Unified_Scores
phone_a phone_b	String	The phone number that is associated with an individual customer record. A customer record may be associated with multiple phone numbers.
pk_a pk_b	String	The combination of data source and primary key allows Amperity to uniquely identify every row in every data table across the entirety of customer data input to Amperity. Tip The combination of pk and datasource uniquely identifies a row in the Unified_Coalesced table, which correlates to a single row in a domain table.
postal_a postal_b	String	The zip code or postal code that is associated with the location of an individual customer record.
score	Float	A score contains a value from 0.0 to 5.0 that represents the combined score assigned to the record pair by Stitch. There are two components of the score: the score itself, and then its strength. The record pair score correlates to the match category, which is a classifier that is applied by Amperity to individual record pairs. The record pair score corresponds to the classification: 5 for exact matches, 4 for excellent matches, 3 for high matches, 2 for moderate matches, 1 for weak matches, and 0 for no matches. The record pair strength represents the strength of the record pair score. It is a two digit number. For example: .31 is a lower strength and .93 is a very high strength. Note Scores are shown for records that end up in the same cluster, including any scores that are below threshold. Scores are not shown for records that do not end up in the same cluster. Also in: Unified_Scores
score_count	String
state_a state_b	String	The state or province that is associated with the location of an individual customer record.
surname_a surname_b	String	The last name that is associated with an individual customer record.

Email_Engagement_Attributes

The Email_Engagement_Attributes table contains many of the same fields as the Email_Engagement_Summary, except for the addition of the Amperity ID field. Whereas the Email_Engagement_Summary table is unique by email and brand (if available), the Email_Engagement_Attributes table is unique by the Amperity ID and email for each brand combination.

Note

In the Email_Engagement_Attributes table, each Amperity ID should only have one email address, per brand.

Tip

The Email_Engagement_Attributes table pulls the email engagement data, for each Amperity ID, from the Email_Engagement_Summary table using the email associated with it in the Merged_Customers table.

Fiscal_Calendar

A fiscal calendar is a yearly accounting period that aligns the weeks and months in a calendar year with holidays and a brand’s marketing goals to align the business for an entire calendar year. A common fiscal calendar used by brands is the 4-5-4 fiscal calendar.

A 4-5-4 calendar divides years into months using a 4 weeks - 5 weeks - 4 weeks pattern. Each week starts on a Sunday and ends on a Saturday. Each quarter has the same number of days. A 4-5-4 calendar can be useful for comparing like days for sales reporting purposes.

The Fiscal_Calendar table is generated by Amperity when fiscal calendar semantic tags are applied to source data tables.

The Fiscal_Calendar table contains the following columns:

Column Name	Data type	Description
calendar_date	Date	The standard calendar date. Important The field to which this semantic tag is applied must also be the primary key for the table.
day_of_week	String	The day of the week on which this calendar date falls.
fiscal_month	String	The fiscal month that is associated with the calendar date.
fiscal_quarter	String	The fiscal quarter that is associated with the calendar date.

fiscal_year	Integer	The fiscal year that is associated with the calendar date.
holiday_sale_name	String	The holiday date (or date range) into which this calendar date falls.

Merged_Customers

The Merged_Customers table is a data table that must be added to a customer 360 database. The purpose of the Merged_Customers table is to collect rows from the Unified_Coalesced table, and then collapse those into a single row per Amperity ID. Columns in the Merged_Customers table are made available to segmentation via the Customer_360 table.

Note

See Merged_Customers for more information about how this table is built and maintained within the customer 360 database.

The Merged_Customers table contains the following columns:

Column Name	Data type	Description
amperity_id	String	This column is input to AmpIQ predictive modeling. The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12.

Additional columns in the Merged_Customer table

The Merged_Customers table contains additional columns that help you understand how and why customer profile values are present in the Merged_Customers table.

These column names start with one of name, address, email, phone, birthday, or gender, and then are grouped as described in the following table. For example: name_completion, name_datasource, name_pk, name_priority, and name_update_dt.

Column Suffix	Description
_completion	The number of NOT NULL values that are present in a set of data, as defined in Merged_Customers. Combine the use of this column with _priority to understand why a record was selected. A name has three possible values (given_name, surname, and full_name). When all three values are NOT NULL, the value in the name_completion column will be 3. An address has four possible values (address, city, state, and postal). When all four values are NOT NULL, the value in the address_completion column will be 4. An email address has one possible value (email). When this value is NOT NULL, the value in the email_completion column will be 1. A phone number has one possible value (phone). When this value is NOT NULL, the value in the phone_completion column will be 1. A birthdate has one possible value (birthdate). When this value is NOT NULL, the value in the birthdate_completion column will be 1. Gender has one possible value (gender). When this value is NOT NULL, the value in the gender_completion column will be 1.
_datasource	The source data table from which the customer profile value originates. Combine the use of this column with _pk to find the record in the source domain table.
_pk	The primary key for the record in _datasource. Combine the use of this column with _datasource to find the record in the source domain table.
_priority	The priority that is assigned to the source domain table in Merged_Customers. Combine the use of this column with _completion to understand why a record was selected.
_update_dt

Opt-in status tables

Standard output tables are available that make available your customer’s preferences for email and phone communications from your brand. Use these preferences to determine when and how your brand can use email and SMS to communicate with your customers.

1. Use the Email_Opt_Status table when your brand communicates with your customers using their email address.

2. Use the SMS_Opt_Status table when your brand communicates with your customers using their phone number.

Email_Opt_Status

The Email_Opt_Status table contains a row for each unique combination of email address, brand, region, and email program.

This table is generated when email-opt/ semantic tags are applied to data sources that contain data that describes your customer’s consent status and gives insight into which customers are available to be used as part an email-based marketing campaign.

Important

Amperity is not the source of truth for email consent status. Email consent status can change quickly, including between the time of this table’s most recent update and the time at which your brand wants to send your customers an email as part of a campaign.

The source of truth for consent status exists downstream from Amperity, often directly within the marketing tool or application that you are using to configure the email campaign, such as Cordial, Braze, Klaviyo, or Attentive.

Use this table to filter audiences in Amperity to include customers who have consented to receiving email messages, and then build a step within the downstream marketing tool that verifies consent status immediately prior to sending an email.

Note

The Email_Opt_Status table represents every email address for which you have provided customer consent data to Amperity. There should be only one consent status by combination of email address, brand, region, or email program.

If you have multiple brands, regions or email programs, it’s possible for the same email address to have more than one customer consent status.

If a brand, region, or email program does not exist, there should be only one customer consent status for each unique email address.

The Email_Opt_Status table contains the following columns:

Semantic Name	Datatype	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles.
brand	String	The brand to which the opt-in status applies.
email	String	The email address that is associated with an individual customer record. A customer record may be associated with multiple email addresses.
email_frequency	String	The preferred frequency for email messages.
email_program	String	The email program to which the customer has opted-in.
is_email_opted_in	Boolean	Indicates whether a customer has given consent to being contacted by your brand using the customer’s email address.
language_preference	String	The customer’s preferred language for email messages.
region	String	The region to which the opt-in status applies.

SMS_Opt_Status

The SMS_Opt_Status table contains a row for each unique combination of phone number, brand, region, and SMS program.

This table is generated when sms-opt/ semantic tags are applied to data sources that contain data that describes your customer’s consent status and gives insight into which customers are available to be used as part an SMS-based marketing campaign.

Important

Amperity is not the source of truth for SMS consent status. SMS consent status can change quickly, including between the time of this table’s most recent update and the time at which your brand wants to send your customers an SMS message as part of a campaign.

The source of truth for consent status exists downstream from Amperity, often directly within the marketing tool or application that you are using to configure the SMS campaign, such as Cordial, Braze, Klaviyo, or Attentive.

Use this table to filter audiences in Amperity to include customers who have consented to receiving SMS messages, and then build a step within the downstream marketing tool that verifies consent status immediately prior to sending an SMS message.

Note

The SMS_Opt_Status table represents every phone number for which you have provided customer consent data to Amperity. There should be only one consent status by combination of phone number, brand, region, or SMS program.

If you have multiple brands, regions or SMS programs, it’s possible for the same phone number to have more than one customer consent status.

If a brand, region, or SMS program does not exist, there should be only one customer consent status for each unique phone number.

The SMS_Opt_Status table contains the following columns:

Semantic Name	Datatype	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles.
brand	String	The brand to which the opt-in status applies.
is_sms_opted_in	Boolean	Indicates whether a customer has opted-in to being contacted by your brand using the customer’s phone number.

audience_size_small	Boolean	A flag that indicates the recommended audience size. When this value is True the recommended audience size is small. A small audience is predicted to include ~50% of future purchasers, while including the fewest non-purchasers. Use a small audience size to help prevent wasted spend and reduce opt-outs.
product_attribute	String	The field against which product affinity is measured. For example: a category, a class, or a brand.
ranking	Integer	A ranking of customers by their score for this product. A rank that is less than or equal to X will provide the top N customers with an affinity for this product.
score	Float	The strength of a customers’s affinity for this product, shown as an uncalibrated probability. Tip The score is used internally by Amperity, does not directly correlate to ranking and/or audience size, and should not be used in segments. Sort results by ranking, and then compare those results to audience sizes. Higher rankings within smaller audience sizes correlate with stronger affinity.

Predicted_CLV_Attributes

The Predicted_CLV_Attributes table contains information, for each individual Amperity ID, about predicted future spend and the probability of churn.

match_category	String	A match category is a classifier that is applied by Amperity to an individual record-pair within a cluster of record-pairs. The match category is the result of this classification. Match Category Description Exact Amperity has the highest confidence that these records represent the same person because all profile data exactly matches. Excellent Amperity has near perfect confidence that these records belong to the same person, despite select types of profile data not matching. High Using deductive reasoning, Amperity has very high confidence that these records match, despite some profile data not matching. Moderate Amperity has moderate confidence that these records match, due to weak or fuzzy matches between highly unique customer attributes (email, phone, address). Weak Amperity lacks confidence, but if asked to guess, Amperity would assert these records do belong to the same individual, because they match on non-unique customer attributes (name, state, zip code). No conflict Amperity has high confidence that these records do NOT match, because core profile data is in conflict.
match_type	String	The type of score being applied. Possible values are as follows: “scored”, “scored_transitive”, and “trivial_duplicate”.
pk1	String
pk2	String
score	Float	A score contains a value from 0.0 to 5.0 that represents the combined score assigned to the record pair by Stitch. There are two components of the score: the score itself, and then its strength. The record pair score correlates to the match category, which is a classifier that is applied by Amperity to individual record pairs. The record pair score corresponds to the classification: 5 for exact matches, 4 for excellent matches, 3 for high matches, 2 for moderate matches, 1 for weak matches, and 0 for no matches. The record pair strength represents the strength of the record pair score. It is a two digit number. For example: .31 is a lower strength and .93 is a very high strength.
source1	String
source2	String

Transaction attributes, extended

The Transaction_Attributes_Extended table contains additional attributes for customer flags, customer orders, data differences, time period rollups, and RFM scores, many of which are represented by duration (days, months, years, lifetime), order position (first, second, last), frequency, and revenue.

Extended transaction attributes–customer flags, customer orders, date differences, time period rollups, and RFM–are also calculated by Amperity based on data sources that contain interaction records that were tagged with transactions and itemized transaction semantics.

Extended transaction attributes are added to the Transaction_Attributes_Extended table, which is an output of Stitch. Extended transaction attributes are fully available to the customer 360 database and to segments.

Extended transaction attributes are presented as a single table (with many columns), including an Amperity ID, and fit into the following categories:

• Customer flags

• Customer orders

• Date differences

• Time period rollups

• RFM

Customer flags

Each record has a set of flags that indicate if a customer has purchased, the number of brand interactions, the number of brand channels, and if that customer is an early repeat purchaser.

amperity_id	String		An Amperity ID is a patented unique identifier that is assigned to clusters of customer records. A single Amperity ID represents a single individual. Unlike other systems, the Amperity ID is reassessed every day for the most comprehensive view of your customers.
early_repeat_purchaser	Boolean		Early repeat purchaser is a flag that indicates if a customer made a repeat purchase within the previous 90 days. Tip Use the early_repeat_purchaser attribute as a leading indicator for overall conversion rate of one-time buyers to repeat customers, even when it does not capture the total number of one-time buyers who have returned to purchase again. Also in: Transaction_Attributes
multi_purchase_brand	Boolean		A flag that indicates if a customer has interacted with more than one brand. This column is calculated from the purchase_brand column in the Unified_Transactions table, which is created when the purchase-brand semantic tag is applied to interaction records that contain transactions data. Also in: Transaction_Attributes
multi_purchase_channel	Boolean		Multi-purchase channel is a flag that indicates if a customer has purchased from more than one channel. This column is calculated from the purchase_channel column in the Unified_Transactions table, which is created when the purchase-channel semantic tag is applied to interaction records that contain transactions data. Also in: Transaction_Attributes
one_and_done	Boolean		One and done is a flag that indicates if a customer has made only one purchase. Important Amperity uses the range of data that is provided to it to identify one-time buyers. For example, if Amperity is provided data for the years 2015-2022, purchases made in 2014 are not used to identify one-time buyers. Also in: Transaction_Attributes

RFM

Amperity calculates RFM scores against transactions that occurred within the last 12 months.

Each of the recency (R), frequency (F), and monetary (M) scores are represented by a number between 0 and 9. The final RFM score is a concatenation of the individual scores: recency first, then frequency, monetary last. The final RFM score is a number between 0 and 999.

Note

RFM uses approximate calculations to optimize the performance of the Transaction_Attributes table.

Column Name	Data type	PII	Description
L12M_rfm_score	Integer		The RFM score for the customer is based on transactions that occurred within the last 12 months. The RFM score is represented as an integer between “111” and “101010”. This is a concatenated score that uses each of the individual recency, frequency, and monetary scores. The order is recency, then frequency, and then monetary. For example, you can build an audience that contains your top 20% customers for recency, your top 30% customers for frequency, and your top 10% customers for monetary by setting the L12M RFM Score attribute to “9810” (or “9” for recency, “8” for frequency, and then “10” for monetary).
L12M_recency	Integer		L12M Recency is a score that sorts customers by how recently they purchased during the previous 12 months. Each RFM score is split into ten percentile groups. The lowest percentile is 1 and the highest percentile is 10. Each percentile represents 10% of the customers who belong to that segment. 10 represents the 90-100th percentile and the customers who have the highest recency, frequency, or monetary scores. 9 represents the 80-90th percentile 8 represents the 70-80th percentile 7 represents the 60-70th percentile 6 represents the 50-60th percentile 5 represents the 40-50th percentile 4 represents the 30-40th percentile 3 represents the 20-30th percentile 2 represents the 10-20th percentile 1 represents the 0-10th percentile and the customers who have the lowest recency, frequency, or monetary scores. Tip Combine percentiles to build larger groups of customers. For example 9 and 10 together represent the “top 20%” while 8, 9, and 10 represent the “top 30%”.
L12M_frequency	Integer		L12M Frequency is a score that sorts customers by purchase frequency during the previous 12 months. Each RFM score is split into ten percentile groups. The lowest percentile is 1 and the highest percentile is 10. Each percentile represents 10% of the customers who belong to that segment. 10 represents the 90-100th percentile and the customers who have the highest recency, frequency, or monetary scores. 9 represents the 80-90th percentile 8 represents the 70-80th percentile 7 represents the 60-70th percentile 6 represents the 50-60th percentile 5 represents the 40-50th percentile 4 represents the 30-40th percentile 3 represents the 20-30th percentile 2 represents the 10-20th percentile 1 represents the 0-10th percentile and the customers who have the lowest recency, frequency, or monetary scores. Tip Combine percentiles to build larger groups of customers. For example 9 and 10 together represent the “top 20%” while 8, 9, and 10 represent the “top 30%”.
L12M_monetary	Integer		L12M Monetary is a score that sorts customers by spend amount during the previous 12 months. Each RFM score is split into ten percentile groups. The lowest percentile is 1 and the highest percentile is 10. Each percentile represents 10% of the customers who belong to that segment. 10 represents the 90-100th percentile and the customers who have the highest recency, frequency, or monetary scores. 9 represents the 80-90th percentile 8 represents the 70-80th percentile 7 represents the 60-70th percentile 6 represents the 50-60th percentile 5 represents the 40-50th percentile 4 represents the 30-40th percentile 3 represents the 20-30th percentile 2 represents the 10-20th percentile 1 represents the 0-10th percentile and the customers who have the lowest recency, frequency, or monetary scores. Tip Combine percentiles to build larger groups of customers. For example 9 and 10 together represent the “top 20%” while 8, 9, and 10 represent the “top 30%”.

Unified_Changes

The Unified_Changes table contains a 30-day rolling history of every change that occurred during a Stitch run. This table is also useful for downstream processes associated with non-customer 360 databases, such as synchronizing Amperity output to external customer-owned systems and the Stitch QA process.

Records may have NULL customer keys. There may be only one customer key per data source. There may be multiple customer keys per Amperity ID. This is because customer keys may also be tagged as foreign keys. Also in: Unified_Customer
component_id	Integer	An identifier that represents a set of records that are transitively connected with a score above threshold as an outcome of blocking and initial scoring. Records that share a component ID, but have different Amperity IDs, were split during hierarchical comparison. Tip Records with different component_id values may show as having been blocked together. This can occur when a connecting record pair was removed because it scored below the pairwise comparison threshold. Also in: Unified_Preprocessed_Raw

The field to which this semantic is applied must be a datetime field type. At least one customer record must have this semantic tag applied to ensure that the update_dt column is created in the Unified_Coalesced table and to ensure that the Merged_Customers table behaves correctly. Also in: Merged_Customers, Unified_Coalesced

Unified_Email_Events

The Unified_Email_Events table contains individual email event information, such as sends, opens, clicks, opt-in and opt-out preferences, bounces, and conversions. This table is added as Stitch output when email event semantic tags are applied to data sources.

Important

This table is only generated when email-events semantic tags are applied to data sources that provide at least 15 months of data for raw email events.

The Unified_Email_Events table contains the following columns:

Unified_Itemized_Transactions

The Unified_Itemized_Transactions table contains every row of every stitched table with all transactional data summarized to the item level, and then coalesced into a single column for each unique combination of order ID and product ID. The order ID is associated with an Amperity ID.

Note

These columns are created when txn-item semantics are applied to interaction records that contain itemized transaction data.

The following diagram shows an example of the Unified_Itemized_Transactions table (click to view a larger diagram):

The Unified_Itemized_Transactions table contains the following columns:

Column Name	Data type	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000
customer_id	String	A custom semantic tag that is applied to interaction records to identify a field that is used in downstream processes to associate interaction records to the Amperity ID. A customer ID may appear once for each unique order ID in the itemized transactions table. Note A namespaced foreign key may be used instead of (or in addition to) a customer ID. Values in this column depend on fields that are tagged with the txn-item/customer-id semantic or a foreign key. Also in: Unified_Transactions
currency	String	Currency represents the type of currency that was used to pay for an item. For example: dollar. Note Currency must be consistent across all orders from the same data source. Values in this column depend on fields that are tagged with the txn-item/currency semantic.
digital_channel	String	The digital channel through which a transaction was made. For example: Facebook, Google Ads, email, etc. Note This column should only have values when purchase-channel specifies an online channel. Values in this column depend on fields that are tagged with the txn-item/digital-channel semantic.
is_cancellation	Boolean	A flag that indicates if the item was cancelled. Values in this column depend on fields that are tagged with the txn-item/is-cancellation semantic. Important This value should be TRUE when items are canceled and FALSE when items are purchases and NULL when the value is unknown.
is_return	Boolean	This column is input to AmpIQ predictive modeling. A flag that indicates if the item was returned. Values in this column depend on fields that are tagged with the txn-item/is-return semantic. Important This value should be TRUE when items are returns and FALSE when items are purchases and NULL when the value is unknown.
item_cost	Decimal	Item cost is the cost to produce all units of an item. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-cost semantic.
item_discount_amount	Decimal	Item discount amount is the discount amount that is applied to all units that are associated with a single item within a single transaction. This value should equal item quantity multiplied by unit discount amounts. This value is used by Amperity for discount sensitivity analysis. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-discount-amount semantic.
item_discount_percent	Decimal	Item discount percent is the percentage discount that is applied to all units that are associated with a single item within a single transaction. This value is used by Amperity for discount sensitivity analysis. Note This value must be between 0 and 1. Values in this column depend on fields that are tagged with the txn-item/item-discount-percent semantic.
item_list_price	Decimal	Item list price is the manufacturer’s suggested retail price (MSRP) for all units of this item. The manufacturer’s suggested retail price (MSRP) is the price before shipping costs, taxes, and/or discounts have been applied. MSRP is sometimes referred to as the base price. This value should equal item revenue plus item discount amount. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-list-price semantic.
item_profit	Decimal	Item profit represents the amount of profit that is earned when all units of an item are sold. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-profit semantic.
item_quantity	Integer	This column is input to AmpIQ predictive modeling. Item quantity is the total number of items in an order. When an item has been returned or an order has been cancelled, item quantity is the total number of items that were returned and/or cancelled. Note This value must be less than or equal to 0 when is-return or is-cancellation are true. Values in this column depend on fields that are tagged with the txn-item/item-quantity semantic.
item_revenue	Decimal	This column is input to AmpIQ predictive modeling. The total revenue for all units of an item, after discounts are applied. When an item has been returned or the order has been cancelled, the total revenue for all items that were returned and/or cancelled. This value should equal item quantity multiplied by unit revenue. Note This value must be less than or equal to 0 when is-return or is-cancellation are true. Tip A return or cancellation is stored as a separate record in the Unified_Itemized_Transactions table and is identified by a value of true in the is_return or is_cancellation column. Values in this column depend on fields that are tagged with the txn-item/item-revenue semantic.
item_subtotal	Decimal	An item subtotal is the amount for an item, before discounts are applied. This value should equal unit list price times item quantity. This value is used by Amperity for discount sensitivity analysis. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-subtotal semantic.
item_tax_amount	Decimal	An item tax amount is the total amount of taxes that are associated with the purchase of an item. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/item-tax-amount semantic.
order_datetime	Datetime	This column is input to AmpIQ predictive modeling. Order datetime is the date (and time) on which an order was placed. Note Other dates associated with an order that are not specific to a transactions, such as dates associated with hotel stays and reservations, should be added to the Unified_Product_Catalog table. When is_return is TRUE, the date and time on which the order was returned. When is_cancellation is TRUE, the date and time on which the order was cancelled. Values in this column depend on fields that are tagged with the txn-item/order-datetime semantic. This column is used to calculate the following transaction attributes: first_order_datetime latest_order_datetime second_order_datetime Also in: Unified_Transactions
order_discount_amount	Decimal	This column is input to AmpIQ predictive modeling. Order discount amount is the total discount amount that is applied to the entire order. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Order discount amounts should be rolled-up to the Unified_Transactions table (from the Unified_Itemized_Transactions table) using one of the following approaches: A pro-rated amount for individual line items: SUM(uit.order_discount_amount) = ut.order_discount_amount An amount for the whole order: MAX(uit.order_discount_amount) = ut.order_discount_amount Caution This value should match the customer’s definition of an order-level discount. For example, some customers associate this value to order value, whereas others associate this value to a subtotal. Use domain SQL to update this field for the desired calculation. Also in: Unified_Transactions
order_id	String	This column is input to AmpIQ predictive modeling. An order ID is the unique identifier for the order and links together all of the items that were part of the same transaction. When an item has been returned or when an order has been cancelled, the order ID is the unique identifier for the original order, including the returned or cancelled items. This field is often the primary key and associated with the pk semantic tag. Note For data that contains itemized transactions, where a single transaction includes more than one of the same item, the order ID will appear more than once. Note The order ID should never change, even when an item in the order is returned or cancelled. Caution If order IDs are recycled and/or are otherwise not guaranteed to be unique over time, the unique identifier for the order must be updated to be a combination of the order ID and the date on which the order occurred. This must be done using domain SQL similar to: CONCAT(order_id, order_date). Values in this column depend on fields that are tagged with the txn-item/order-id semantic. The combination of order_id and product_id must be unique for each row in this table. This column is used to calculate the following transaction attributes: first_order_id L30D_average_num_items L30D_average_order_value L30D_order_frequency latest_order_id lifetime_average_num_items lifetime_average_order_value lifetime_order_frequency second_order_id Also in: Unified_Transactions
payment_method	String	A payment method is how a customer chose to pay for the items they have purchased. For example: credit card, gift card, or cash. Values in this column depend on fields that are tagged with the txn-item/payment-method semantic.
Product catalogs	String	Optional Product catalog fields are added to the Unified_Itemized_Transactions table in two ways, depending on the approach your tenant used for defining your product catalog: When data sources use txn-item/ product catalog semantic tags. When product catalog fields are joined from the Unified_Product_Catalog table. Refer to the section in this topic about the columns that are available to product catalogs. Important The names of the columns that are available for product catalogs are identical. For example: “product_brand”, “product_category”, and “product_gender”. The difference is the outcome of the approach your tenant used to define your product catalog within Amperity.
product_id	String	This column is input to AmpIQ predictive modeling. The unique identifier for a product. A stock keeping unit (SKU) is an identifier that captures all of the unique details of any individual product, including specific attributes that differentiate by color, size, material, and so on. For example, a shirt with the same color and material, but with three different sizes would be represented by three unique SKUs and would also be represented by three unique product IDs. Note For data that contains itemized transactions, where a single transaction includes more than one of the same product, the product ID will appear more than once. Caution Every customer has their own definition for SKUs and product IDs. Be sure to understand this definition before applying semantic tags to fields with product IDs to ensure they accurately reflect the customer’s definition. Values in this column depend on fields that are tagged with the txn-item/product-id semantic. The combination of order_id and product_id must be unique for each row in this table; product quantity is counted using item_quantity. Important This column is recommended when using a product catalog. A product catalog is a requirement for certain predictive features of AmpIQ, such as for product affinity and audience sizes.
purchase_brand	String	The brand for which a transaction was made. Note This column should only have values when interaction records contain transactions data for more than one brand. Values in this column depend on fields that are tagged with the txn-item/purchase-brand semantic. This column is used to calculate the following transaction attributes: multi_purchase_brand.
purchase_channel	String	This column is input to AmpIQ predictive modeling. A purchase channel is the channel from which a transaction was made. For example: in-store or online. Values in this column depend on fields that are tagged with the txn-item/purchase-channel semantic.
store_id	String	A store ID is a unique identifier that is identified with the location of a store. Values in this column depend on fields that are tagged with the txn-item/store-id semantic.
unit_cost	Decimal	Unit cost is the cost to produce a single unit of one item. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-cost semantic.
unit_discount_amount	Decimal	Unit discount amount is the discount amount that is applied to a single unit of one item. This discount is often applied to all units of the same item within a single transaction. This value is used by Amperity for discount sensitivity analysis. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-discount-amount semantic.
unit_list_price	Decimal	Unit list price is the manufacturer’s suggested retail price (MSRP) for a single unit of an item. The manufacturer’s suggested retail price (MSRP) is the price before shipping costs, taxes, and/or discounts have been applied. MSRP is sometimes referred to as the base price. This value should equal the unit discount amount plus the unit subtotal. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-list-price semantic.
unit_profit	Decimal	Unit profit represents the amount of profit that is earned when a single unit of an item is sold. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-profit semantic.
unit_revenue	Decimal	The total revenue for a single unit of an item. When an item has been returned or the order has been cancelled, the total revenue for a single unit of an item that was returned and/or cancelled. Note This value must be less than or equal to 0 when is-return or is-cancellation are true. Values in this column depend on fields that are tagged with the txn-item/unit-revenue semantic.
unit_subtotal	Decimal	A unit subtotal is the amount for a single unit of one item, before discounts have been applied. This value is used by Amperity for discount sensitivity analysis. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-subtotal semantic.
unit_tax_amount	Decimal	A unit tax amount is the total amount of taxes that are associated with a single unit. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Values in this column depend on fields that are tagged with the txn-item/unit-tax-amount semantic.
Custom attributes	Varies	You may extend the Unified_Itemized_Transactions table to define custom attributes for use with a product catalog. Important This column is recommended when using a product catalog. A product catalog is a requirement for certain predictive features of AmpIQ, such as for product affinity and audience sizes. Add custom attributes to the Unified_Itemized_Transactions table by extending it to add columns that support using a product catalog. Custom attributes should include the columns to which product catalog semantic tags were applied, but may include additional custom attributes that are unique to your tenant and your brands. Important The Unified_Product_Catalog table represents the taxonomy for your products and brands. Attributes are added to the Unified_Product_Catalog table when pc/ semantic tags are applied to your data sources. All pc/ semantic tags are optional. Use the ones that best define the shape of your product catalog and best describe the individual items within it. The product ID is used as an input to AmpIQ predictive modeling.

The Unified_Loyalty table contains the following columns:

Column Name	Data type	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note Loyalty profiles are unique by Amperity ID when: The fk-loyalty-id semantic tag is applied to the same source field as the loy/loyalty-id field. The loy/email semantic tag is applied to fields that contain email addresses. The loy/birthdate semantic tag is applied to fields that contain birthdates.

Unified_Preprocessed_Raw

The Unified_Preprocessed_Raw table is an output of Stitch. Use this table as part of Stitch QA to view data exactly how values were used by Stitch after preprocessing and blocklisting. This table contains one row for each trivial duplicate. Only the semantics used by Stitch are shown. Semantic values represent pre-processing values and/or bad values that were removed (and replaced by NULL).

Tip

Because there is only one row per trivial duplicate, join this table on the Unified_Coalesced table for ongoing usage. For example:

SELECT *
FROM unified_coalesced uc
JOIN unified_preprocessed_raw up
ON uc.rep_ds=up.datasource AND uc.rep_pk=up.pk

The Unified_Preprocessed_Raw table contains the following columns:

Column Name	Data type	Description
amperity_id	String	The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000

component_id	Integer	An identifier that represents a set of records that are transitively connected with a score above threshold as an outcome of blocking and initial scoring. Records that share a component ID, but have different Amperity IDs, were split during hierarchical comparison. Tip Use this field during the Stitch QA process to help identify why certain records were grouped (or not grouped) together. Also in: Unified_Preprocessed_Raw
datasource	String	The name of the data source from which this customer record originated. Tip The combination of pk and datasource uniquely identifies a row in the Unified_Preprocessed_Raw table, which correlates to a single row in a domain table.
email	String	The email address that is associated with an individual customer record. A customer record may be associated with multiple email addresses. Also in: Customer_360, Merged_Customers, Unified_Coalesced, Unified_Customer
fk_[name]	String	The fk-[namespace] semantic tag identifies a field as a foreign key. A foreign key semantic tag must be namespaced. For example: fk-customer, fk-interaction, fk-audience, or fk-brand. A column is added for each foreign key that is defined in the Sources tab.

Unified_Scores

The Unified_Scores table records all of the pairwise comparison scores and match categories for all groups of records, and then for each group of records all of the pairwise scores that are present between records within that group.

Note

See Unified_Scores for more information about how this table is built and maintained within the customer 360 database.

The Unified_Scores table contains the following columns:

Column Name	Data type	PII	Description
amperity_id	String		The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000
source1	String
source2	String
pk1	String
pk2	String
score	Float		A score contains a value from 0.0 to 5.0 that represents the combined score assigned to the record pair by Stitch. There are two components of the score: the score itself, and then its strength. The record pair score correlates to the match category, which is a classifier that is applied by Amperity to individual record pairs. The record pair score corresponds to the classification: 5 for exact matches, 4 for excellent matches, 3 for high matches, 2 for moderate matches, 1 for weak matches, and 0 for no matches. The record pair strength represents the strength of the record pair score. It is a two digit number. For example: .31 is a lower strength and .93 is a very high strength. Note Scores are shown for records that end up in the same cluster, including any scores that are below threshold. Scores are not shown for records that do not end up in the same cluster. Also in: Detailed_Examples
match_category	String		A match category is a classifier that is applied by Amperity to an individual record-pair within a cluster of record-pairs. The match category is the result of this classification. Match Category Description Exact Amperity has the highest confidence that these records represent the same person because all profile data exactly matches. Excellent Amperity has near perfect confidence that these records belong to the same person, despite select types of profile data not matching. High Using deductive reasoning, Amperity has very high confidence that these records match, despite some profile data not matching. Moderate Amperity has moderate confidence that these records match, due to weak or fuzzy matches between highly unique customer attributes (email, phone, address). Weak Amperity lacks confidence, but if asked to guess, Amperity would assert these records do belong to the same individual, because they match on non-unique customer attributes (name, state, zip code). No conflict Amperity has high confidence that these records do NOT match, because core profile data is in conflict. Also in: Detailed_Examples
match_type	String		The type of score being applied. Possible values are as follows: “scored”, “scored_transitive”, and “trivial_duplicate”. A match is assigned “scored_transitive” when that match was not identified during blocking. For example: three records (A, B, and C). If records A and B and records B and C were identified as matching during blocking, all three records will end up in the same group of records for pairwise comparison. Records A and C have a transitive connection.

Unified_Transactions

The Unified_Transactions table contains one row for each unique transaction record, with each order ID associated to an Amperity ID.

The following diagram shows an example of the Unified_Transactions table (click to view a larger diagram):

The Unified_Transactions table contains the following columns:

Column Name	Data type	Description
amperity_id	String	This column is input to AmpIQ predictive modeling. The unique identifier that is assigned to clusters of customer records that all represent the same individual. The Amperity ID does not replace primary and foreign keys, but exists alongside them within unified profiles. Note The Amperity ID is a universally unique identifier (UUID) that is represented by 36 characters spread across five groups separated by hyphens: 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000

customer_id	String	A custom semantic tag that is applied to interaction records to identify a field that is used in downstream processes to associate interaction records to the Amperity ID. A customer ID may appear once for each order ID in the transactions table. When a foreign key is not present, the customer ID is used to join interaction records (transactions and itemized transactions) to tables that contain the Amperity ID. Note A namespaced foreign key should be used along with a customer ID. When a foreign key is added to transactions data it: Must match a foreign key in a table that is output by Stitch Must be well-distributed across the data source (a high percentage of values must not be 0) May contain a NULL value Must be unique for each order ID in the Unified_Transactions table. Also in: Unified_Itemized_Transactions
digital_channel	String	The digital channel through which a transaction was made. For example: Facebook, Google Ads, email, etc. Note This column should only have values when purchase-channel specifies an online channel.

This value should match the sum of the revenue for all items in the itemized transactions that were cancelled. Important This value must be less than or equal to 0 when is_cancelled is TRUE.
order_cost	Decimal	Order cost represents the total cost of goods sold (COGS) for a single transaction. Cost of goods sold (COGS) are the direct costs of producing goods that are sold by a brand, including the costs of materials and labor to produce the item, but excluding indirect expenses like distribution or sales. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. Warning Only one of order-profit and order-cost may be present for a transaction.

The order date: Must have a consistent time zone across all dates in the transactions data. Should be a local time zone. Should be a timestamp, which is converted to datetime automatically when a date is present in the timestamp. Note Other dates associated with an order that are not specific to a transactions, such as dates associated with hotel stays and reservations, should be added to the Unified_Product_Catalog table. This column is used to calculate the following transaction attributes: first_order_datetime latest_order_datetime second_order_datetime Also in: Unified_Itemized_Transactions
order_discount_amount	Decimal	This column is input to AmpIQ predictive modeling. Order discount amount is the total discount amount that is applied to the entire order. Note This value must be greater than or equal to 0 for purchases, but less than or equal to 0 for returns or cancellations. This value is used by Amperity for discount sensitivity analysis. Caution This value should match the customer’s definition of an order-level discount. For example, some customers associate this value to order value, whereas others associate this value to a subtotal. Use domain SQL to update this field for the desired calculation. Also in: Unified_Itemized_Transactions
order_discount_percent	Decimal	Order discount percent is the percentage discount that is applied to the order value for the entire transaction, in addition to any item or unit-specific discount percentages. This value may be used as an input to order discount amount. Note This value must be between 0 and 1. This value is used by Amperity for discount sensitivity analysis. Caution This value should match the customer’s definition of an order-level discount percentage. For example, some customers associate this value to order value, whereas others associate this value to a subtotal. Use domain SQL to update this field for the desired calculation.
order_id	String	This column is input to AmpIQ predictive modeling. An order ID is the unique identifier for the order and links together all of the items that were part of the same transaction. When an item has been returned or when an order has been cancelled, the order ID is the unique identifier for the original order, including the returned or cancelled items. This column is the primary key and must be associated with the pk semantic tag. Each unique order ID must: Appear only once in the Unified_Transactions. Match an order ID in the Unified_Itemized_Transactions table. (This order ID might be associated to multiple items within a single transactions.) Note The order ID should never change, even when an item in the order is returned or cancelled. Caution If order IDs are recycled and/or are otherwise not guaranteed to be unique over time, the unique identifier for the order must be updated to be a combination of the order ID and the date on which the order occurred. This must be done using domain SQL similar to: CONCAT(order_id, order_date). This column is used to calculate the following transaction attributes: first_order_id L30D_average_num_items L30D_average_order_value L30D_order_frequency latest_order_id lifetime_average_num_items lifetime_average_order_value lifetime_order_frequency second_order_id Also in: Unified_Itemized_Transactions
