Mapplet Transformation Use
You can use the Mapplet transformation to extend Informatica Cloud data transformation capabilities or to reuse or hide transformation logic.
Use a Mapplet transformation to accomplish the following goals:
- Extend the data transformation capabilities of Informatica Cloud.
- For example, you want to create a mapping that passes customer records to a target if the customers pass a credit check. In PowerCenter, you create a Web Services Consumer transformation to run a credit check on each customer. You include the Web Services Consumer transformation in a mapplet and create a mapping, session, and workflow that contains the mapplet. After you import the workflow XML file into Informatica Cloud, you can use the mapplet in a mapping to perform the credit check.
- Reuse transformation logic in different mappings.
- For example, you have different fact tables that require a series of dimension keys. In PowerCenter, you create a mapplet that contains a series of Lookup transformations to find each dimension key. You include the mapplet in a mapping, session, and workflow, and export the workflow to an XML file. After you import the XML file into Informatica Cloud, you can use the mapplet in different fact table mappings instead of re-creating the lookup logic in each mapping.
- Hide complex transformation logic.
- The Mapplet transformation shows the mapplet incoming and outgoing fields. It does not display the PowerCenter transformations that the mapplet contains.
