A CSV file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format.

currency: Currency represents the type of currency that was used to pay for an item. For example: dollar.

custom core table: A custom core table is built using Spark SQL and may reference one (or more) core tables and/or domain tables. Use custom core tables to extend the normalized foundation to support additional use cases beyond what the set of standard core tables provides.

custom database table: A custom database table exists when domain SQL is used to build a domain table. These tables are used as inputs for standard database tables when semantic tags are applied and may be passed through to any database.

customer: A customer is a known individual with a core set of associated personally identifiable properties, such as their given name, surname, birthdate, mailing address, email address, and phone number.

customer 360 database: A customer 360 database is built using standard core tables that are generated by the Stitch process. These tables provide a unified view of your brand’s customer data, including customer profiles and interaction records, that is organized, merged, and linked together by the Amperity ID.

customer 360 profile: Amperity creates a unique profile for each unique customer record, and then stores these profiles in the Customer 360 table. Each unique profile is assigned an Amperity ID. Amperity calculates the number of unique profiles by counting the number of Amperity IDs in the Customer 360 table.

Customer 360 page: The Customer 360 page provides the interface to view and manage all databases, including the customer 360 database, along with related customer profile and interaction data. Explore and interact with stitched tables. Use Spark SQL to build the customer 360 database, add tables, define predictions, and surface data points that can be used with queries and segments.

C360, Customer 360 (data table): 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.

Customer Attributes: The Customer Attributes table contains a series of columns that identify attributes about individuals, such as if that individual can be contacted, if a marketable email address, physical address, or phone number is available, if they are an employee, reseller, or if the individual represents a test account, along with identifying each individuals’s revenue relationship with a brand.

customer lifecycle status

Customer lifecycle status is represented by a probabilistic score–referred to as p(return) or “probability of return”–that identifies if a customer is active or if they are likely to churn.

A customer’s p(return) score determines the customer lifecycle status tier to which they are assigned:

Status tier	p(return) score
Active	p(return) score is over 60%
Cooling down	p(return) score is between 50%-60%
At risk	p(return) score is between 35%-50%
Highly at risk	p(return) score is between 20%-35%
Lost	p(return) score is below 20%

customer lifetime value (CLV): See CLV.

customer profile: 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.

customer record: A customer record is a row in a customer data table that contains information (columns) about the customer. Who they are, where they live, and how much they spend. For example, a email list table contains names, email addresses, phone numbers, and so on. All domain tables that contain customer records are stitched together to create Amperity IDs.

The Customer 360 page opens the Data Explorer to a view that shows all tables in the database, from which you may view each of the individual tables.
The Segments page opens the Data Explorer to a specific table, and then provides a view of its schema along with sample data.

The data explorer, as opened from within the Stitch page in Amperity.

data lineage: Data lineage is a graph visualization that shows how all of the data within your tenant connects.

data mapping: A data mapping template defines how columns in Amperity output are mapped to fields or columns required by a destination, including the ordering and naming of columns. This is especially useful when a destination has case-sensitive column names or when it uses a REST API with specific requirements for naming patterns. A destination that does not have requirements for the shape of data should use null instead of defining a data mapping structure.

data source: A data source is a system in a customer’s environment that sends data to Amperity as structured or semi-structured data via a filedrop or REST API.

data subject access request (DSAR): A data subject access request (DSAR) is a written request made by an individual to ask for their data to be handled according to regulations, such as General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA).

A pairwise connection is a pair of matching records within a block that have an initial score above threshold. Each pairwise connection within a block is scored, after which all pairwise connections that scored above threshold represent a single, unique individual.

See cluster graph and stitched records.

pairwise connection score

A score is assigned to every pairwise connection. The score is measured in two parts, separated by a period.

The first part–the record pair score–correlates to the match category, which is a machine learning 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 non-matches.

The second part–the record pair strength–is used by Stitch to help determine the quality of the record pair score. This value appears in the Stitch report as a two decimal number. A record pair strength by itself is not a direct indicator of the quality of a pairwise connection score.

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.

transitive connection: A transitive connection exists between individual records when any two records share a strong match to an intermediate record, but do not have a strong match to each other. For example: record 1 matches record 2, record 3 matches record 2, neither records 1 or 3 match to each other, but they have a transitive connection because both match record 2.

treatament group: A treatment group is the percentage of an audience who will receive communications related to a marketing campaign. A campaign may have more than one treatment group.

Trino: Trino is a distributed SQL query engine that is designed to efficiently query vast amounts of data using distributed queries. Trino is used by the Amperity SQL segment editors to define segments, which are SQL queries that return data from stitched data tables. Formerly known as Presto SQL.

trivial duplicate

A trivial duplicate is a set of nearly-identical records that share enough matching PII to clearly identify a single unique individual. Trivial duplicates are identified by Stitch early in the identity resolution process. Only one of these records is passed downstream for additional Stitch processing; the other records—the trivial duplicates—are not.

See qualified trivial duplicate.

TSV, tab-separated value: A tab-separated values (TSV) file is a delimited text file that uses a tab to separate values and stores tabular data (numbers and text) in plain text. Each line in the file is a data record. Each record consists of one or more fields, separated by tabs.

U¶

UID2 tokens: A Unified ID 2.0 (UID2) token, also called an advertising token, is an encrypted form of a raw UID2 value. UID2 tokens are generated from a user’s email address. UID2 tokens are case sensitive, are unique, and are refreshed periodically.

undercluster: An undercluster, or a false negative, occurs when distinct records are incorrectly split from a cluster of records. Each undercluster affects the precision of identity resolution and should be investigated to understand why it occurred.

Unified ID 2.0: Unified ID 2.0 is an open source identity framework that benefits consumers by allowing them to control how their data is shared with publishers and advertisers.

Unified Compliance: The Unified Compliance table supports privacy rights workflows and contains the search results for data subject access requests (DSAR) and customer delete requests. A row is added to the the Unified Compliance table for each matching record.

Unified Customer: The Unified Customer table contains every row of every stitched table with all semantics coalesced into a single column, with two exceptions that are removed from the table: values from a bad-values blocklist and values associated with supersized clusters. A unique Amperity ID may appear in more than one row.

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.

Unified Itemized Transactions: The Unified Itemized Transactions table contains rows of 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.

Unified Loyalty: The Unified Loyalty table contains a row for every customer who belongs to your loyalty program, unique by combination of Amperity ID and loyalty ID.

Unified Loyalty Events: The Unified Loyalty Events table contains a row for loyalty program events, unique by Amperity ID and event datetime.

Unified Paid Media: The Unified Paid Media table builds customer profiles that contain all known PII—including email addresses, phone numbers, names, and physical addresses—for each Amperity ID. This is different from the Merged Customers table, which contains only the best PII for each Amperity ID. Use the Unified Paid Media to help increase the total number of matched customers with your paid media campaigns.

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).

Unified Product Catalog: The Unified Product Catalog table contains a row for every item in your product catalog, including descriptive attributes, such as name, brand, size, and color, grouping attributes, such as category, sub-category, class, and sub-class, and other attributes like MSRP, gender, and description.

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.

unified tables

Unified tables are generated by Stitch and consolidate your brand’s customer profile, transaction, and interaction records into a series of tables, in which rows of records are unified by the Amperity ID.

See stitched domain tables and Stitch QA tables.

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

uniqueness: Uniqueness divides the number of unique values—cardinality—by the number of rows in a table.

unit cost: Unit cost is the cost to produce a single unit of one item.

unit discount amount: Unit discount amount is the discount amount that is applied to a single unit of one item.

unit list price: Unit list price is the manufacturer’s suggested retail price (MSRP) for a single unit of an item.

unit profit: Unit profit represents the amount of profit that is earned when a single unit of an item is sold.

unit revenue: The total revenue for a single unit of an item. When an item has been returned or the order has been canceled, the total revenue for a single unit of an item that was returned and/or canceled.

unit subtotal: A unit subtotal is the amount for a single unit of one item, before discounts have been applied.

unit tax amount: A unit tax amount is the total amount of taxes that are associated with a single unit.

units per transaction: See UPT.

unqualified trivial duplicate

An unqualified trivial duplicate is a set of records that do not have enough matching PII to score 3.0 (or greater) and cannot be grouped together.

See trivial duplicate.

unstructured data: Unstructured data is data that does not adhere to a particular data model or definition, such as text or binary data.

Note

Amperity (generally) does not support unstructured data as a data source because it cannot be easily mapped to other data sources. As such, it is less useful for identifying common patterns and trends across many data sets.

UPC code: A Universal Product Code (UPC or UPC code) is a barcode that is widely used to track items in stores.

UpSet Plot: An UpSet plot highlights the connectivity between data sources. Similar to a Venn diagram, an UpSet Plot helps you to visualize the intersections of different data sources. Different from a Venn diagram, an UpSet Plot contains additional visualizations that are broken down by data source. Each bar in the UpSet Plot shows the number of Amperity IDs that share records from the included sources. Therefore, each bar represents a mutually exclusive set of Amperity IDs. If you were to add up all the Amperity IDs for each bar, you’d see the total number of Amperity IDs for the selected data source.

UPT, units per transaction: The average number of items purchased in any given transaction.

upstream: Upstream refers to the part of a workflow that occurs before the current step, often with some type of dependency. For example, a data table is only updated when new customer data is provided.

Urban Airship: See Airship.

UUID, universally unique identifier: A universally unique identifier (UUID) is a 128-bit number that uniquely identifies information in a computer system. It is represented by 32 digits and four characters (hyphens) displayed in five groups separated by hyphens in the form of 8-4-4-4-12. For example: 123e4567-e89b-12d3-a456-426614174000.
