The PowerCenter Integration Service stores TDM components in the TDM repository.
A data masking, data generation, or data subset workflow requires a connection to the TDM repository.
When you run profiles to discover data, the TDM Server sends a request to the Data Integration Service to extract data for the source tables. The Data Integration Service sends a request to its associated Model Repository Service to load the metadata for the tables to the Model repository. 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.
The Data Integration Service loads the profile results to the profiling warehouse. When you create a Data Integration Service in the Administrator tool, you configure a profiling warehouse.
When you import metadata into Test Data Manager from a PowerCenter source, the TDM Server sends a request to the PowerCenter Repository Service to copy source metadata from the PowerCenter repository into the TDM repository.
