Information
The Lifeline of Informatica - Transformations
- Adding transformation in mapping
- Ports of transformation
- Various transformations such as Expression, Aggregator, Sorter, Filter, Router, Lookup, Sequence Generator, Update Strategy, and so on
- Classification of transformation
- Tracing levels
Creating the transformation
Mapping Designer
- Open the Mapping in Mapping Designer. Then open the mapping in which you wish to add transformation, and click on Transformation | Create as shown:
- From the drop-down list of transformations, select the transformation you wish to create, specify the name, and click on Create and then Done:
Mapplet Designer
- Open the Mapplet in Mapplet Designer, and click on Transformation | Create as shown previously.
- From the drop-down list of transformations, select the transformation you wish to create, and specify the name.
Transformation Developer
- Open the Transformation Developer, and go to Transformation | Create as shown previously under Mapping Designer.
- From the drop-down list of transformations, select the transformation you wish to create, and specify the name as shown in the preceding section under Mapping Designer.
Expression transformation
- Create the source using the flat file in Source Analyzer and target in Target Designer. We will be using EMP_FILE as the source and TGT_EMP_FILE as the target.
- Create a new mapping m_EXP_CONCAT_TOTAL in mapping designer, drag the source and target from Navigator to Workspace, and create the Expression Transformation with the name EXP_CONCAT_TOTAL.
- Drag all the columns from source qualifier to expression transformation. At this point, the mapping will look like this:
