TDM connects to databases, repositories, and services to perform data subset, masking, 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, and external database sources.
