To transform relational data to hierarchical data, the wizard creates a hierarchical structure that reflects the relational input ports. You can use the
Overview
View to link relational ports to hierarchical ports.
To view the links between relational input to hierarchal output, use the
Overview
view. Select
Input Mapping
. The
Ports
panel appears in the
Overview
view.
The following image shows the
Ports
panel:
To the left of the
Ports
panel is the
Transformation input
area that contains the relational elements and groups. To the right is the
Transformation output
area that contains the hierarchical schema nodes.
You can create ports in the
Transformation input
area, and link relational elements to the schema nodes. You can also drag the pointer from a node in the schema to an empty field in the
Transformation input
area to create a port. When you connect a relational port to a schema node, the Developer tool shows a link between them.
