Source Mapplets

Source Mapplets

You can run a profiling task on the output from a source mapplet that you create in
Data Integration
. A source mapplet is a mapplet that has a source connection and a single output. You can also run a profiling task on a mapplet as a source object.
Before you use the mapplet as a source connection, make sure that source connections used in a mapplet are associated with an active Secure Agent.
The following image shows a source mapplet that has multiple source connections, transformations, and a mapplet output: The mapplet contains an Oracle source, SQL source, and real-time source. Multiple transformations read the sources and write the transformed data to a single output.
