TDM connects to databases, repositories, and services to perform data subset, masking, generation, and profiles for discovery operations. The connection requirements are based on the operations that you need to perform.
To perform data discovery operations, TDM requires connections to a database source and a Data Integration Service.
To perform data masking and data movement operations on Hadoop, TDM requires connections to Hadoop sources and a Data Integration Service.
Workflows for data subset and masking operations require connections to services, the TDM repository, external database sources, and PowerCenter sources and targets.
Workflows for operations to store data in the test data warehouse require connections to the test data repository and to the test data mart.
To run workflows to copy flat file results to a test tool, you must first integrate the test tool server with TDM. TDM connects to the integrated server to copy the flat file to the configured location.
