MRX Views

The MRX views provide an interface to interrogate information about objects in the MRS. That information is more limited than the information provided by the MX views in a PowerCenter repository.

MRX views are classified into the following categories:

  • Design-time metadata
  • Deployed metadata
  • Domain
