The following image shows the architecture components for the test data warehouse:

When you run a plan to create a data set, the Test Data Warehouse Service stores the project and source table metadata in the test data warehouse repository. The service creates the tables in the test data warehouse. The PowerCenter Integration Service then moves the data into the tables in the test data warehouse.

The following table describes the architecture components:

Component	Description
Test Data Manager	A web-based client that you can use to perform data discovery, data subset, data masking, and data generation operations.
Informatica Administrator	A web application that you can use to manage, monitor, deploy, and undeploy data flows.
Test Data Manager Service	An application service that runs Test Data Manager and manages connections between service components and Test Data Manager users.
PowerCenter Repository Service	An application service that manages the PowerCenter repository where the metadata for workflows and mappings that you generate in Test Data Manager are stored.
PowerCenter Integration Service	An application service that runs sessions and workflows that you run from Test Data Manager.
Test Data Warehouse Service	An application service that runs the test data warehouse and manages the test data warehouse repository and the test data warehouse.
Service Manager	The Informatica Service that manages all domain operations and manages the domain configuration repository.The Informatica Service that manages all domain operations and manages the domain configuration repository.
TDM repository	A relational database that stores the components that you define in Test Data Manager, such as policies, projects, entities, and rules. The TDM repository stores metadata that you import into Test Data Manager from a source database or from the PowerCenter repository.
Test data warehouse repository	A relational database that stores the source table metadata and project metadata for data sets that you create in Test Data Manager.
Test data warehouse	A relational database that stores the source data that you include in a data set.
Domain configuration repository	A relational database that stores the connections used to run profiles, users for the Informatica domain, and metadata for the Informatica domain.
PowerCenter repository	A relational database that stores the metadata for workflows and mappings that you generate from Test Data Manager.
