Change Data from PowerExchange Change Data Capture Sources

Change Data from PowerExchange Change Data Capture Sources

Change data from PowerExchange change data capture sources represents changes to a file or relational database. PowerExchange captures change data and stores it in the change stream. Use PowerExchange Client for PowerCenter to extract changes from the PowerExchange change stream.
PowerExchange Client for PowerCenter connects to PowerExchange to extract data that changed since the previous session. The Integration Service processes and writes change data to a target.
PowerExchange Client for PowerCenter, PowerExchange, and the Integration Service complete the following tasks to process change data:
  1. PowerExchange Client for PowerCenter connects to PowerExchange.
  2. PowerExchange extracts change data from the change stream.
  3. PowerExchange passes change data to the Integration Service through PowerExchange Client for PowerCenter.
  4. The Integration Service transforms and writes data to a target.
