TDM connects to databases for metadata, profiling, TDM configuration, domain configuration, and the test data warehouse.
TDM needs connections to the following databases:
TDM repository
A relational database that contains tables that TDM requires to run and the tables that store metadata.
Model repository
A relational database that stores table metadata for data discovery profiles and the connections that you create in Test Data Manager. When you perform data masking and data movement operations on Hadoop, you can choose to store the mappings in the Model repository for future use.
PowerCenter repository
A relational database that stores metadata for PowerCenter sources and targets. The PowerCenter repository also stores metadata for the workflows that you generate from plans in Test Data Manager.
Profiling warehouse
A relational database that stores profile results for data discovery.
Domain configuration repository
A relational database that stores connections and metadata for the Informatica domain.
Test data warehouse repository
A relational database that stores the project metadata and source table metadata for data sets that you store in the test data warehouse.
Test data warehouse
A relational database that stores the source data of data sets that you store in the test data warehouse.
