Pushdown Optimization to PowerExchange Nonrelational Sources

Pushdown Optimization to PowerExchange Nonrelational Sources

For PowerExchange nonrelational data sources on z/OS systems, the Data Integration Service pushes Filter transformation logic to PowerExchange. PowerExchange translates the logic into a query that the source can process.
The Data Integration Service can push Filter transformation logic for the following types of nonrelational sources:
  • IBM IMS
  • Sequential data sets
  • VSAM
