Test Data Management (TDM)

The Informatica solution that bundles Data Subset, Data Generation, and Data Masking to protect sensitive data and create lean nonproduction systems for test and development purposes.

data discovery

The process of discovering the metadata of source systems that includes content, such as data values and frequencies, and structure such as primary keys, foreign keys, and functional dependencies.

data generation

The process to generate realistic test data for the testing environment without using the production data.

data masking

The process of replacing sensitive columns of source data with realistic test data.

data subset

A small, targeted, and referentially intact copy of production data.

entity

Defines a set of tables that are related based on physical or logical constraints. An entity can contain parent tables and child tables. An entity maintains relational hierarchy in the tables. Define filter parameters for ports in the entity to extract the columns from the tables in an entity. When you run a workflow generated from a data subset plan, the PowerCenter Integration Service extracts source data based on the filter parameters defined in the entity and loads the data to the subset tables.

foreign key profile

A type of data analysis that finds column values in a data source that match the primary key column values in another data source.

plan

Defines data subset, data masking, or data generation operations. You can add entities, groups, templates, policies, rules, and tables to a plan. When you generate and run workflows from a plan, the PowerCenter Integration Service generates and runs the workflows.

project

A container component for entities, groups, templates, and one or more sources that you want to use in data discovery, subset, and masking operations. When you create a project, you add one or more sources to the project. Any source that you add to a project is not available to other projects.

rule

Defines the data masking technique, an optional rule qualifier, and masking parameters.

TDM repository

A relational database that stores the components that you define in Test Data Manager, such as policies, projects, entities, and data masking rules. The TDM repository stores metadata that you import into Test Data Manager from a source database or from the PowerCenter repository. The TDM repository stores constraints that define relationships between the source tables in a project.

TDM Server

Server that runs Test Data Manager and integrates with Informatica application services to perform data subset, data masking, and data discovery operations.

Test Data Manager

The web-based user interface that you use to configure and run data subset, data masking, and discovery operations.
