How to Develop a Mapping

How to Develop a Mapping

Develop a mapping to read, transform, and write data according to your business needs.
To develop and run a mapping, perform the following tasks:
  1. Determine the type of mapping that you want to create.
  2. Create input, output, and reusable objects such as the reusable transformations and mapplets that you want to use in the mapping.
    You can use physical data objects, logical data objects, or virtual tables for mapping input and output.
  3. Create the mapping.
  4. Add objects to the mapping. You must add input and output objects to the mapping. Optionally, add transformations and mapplets.
  5. Link ports between mapping objects to create a flow of data from sources to targets, through mapplets and transformations that add, remove, or modify data along this flow.
  6. Validate the mapping to identify errors.
  7. Save the mapping to the Model repository.
  8. Run the mapping to see the mapping output.
