Relational Input and Output Overview

Relational Input and Output Overview

A Data Processor transformation can read relational database input from input ports and transform it into other formats. A transformation can output rows of relational data to output ports. You can define the mapping with Data Processor transformation ports on the transformation Overview view. Or you can use the Data Processor transformation wizard to automatically map relational data.
You can transform relational data to hierarchical data. To transform input groups into hierarchal data, map nodes from group of relational ports to the hierarchical ports. You can pass the data from the hierarchical output ports to another transformation in the mapping.
You can return relational output from the Data Processor transformation. If a component returns relational data, you create groups of output ports by mapping nodes from the hierarchical input to groups of relational ports. You can pass the data from the relational output ports to another transformation in a mapping.
