You create one hundred mappings and an incremental application that contains the mappings. Then, you deploy the application to a Data Integration Service. After testing the output of the application objects, you make changes to a few of the objects.

To update the objects in the run-time application, you create an application patch that contains the objects that you changed. You deploy the application patch to the Data Integration Service and the service applies the patch to the incremental application to update the objects without stopping other application objects that other users might be running. You also deploy the application and the application patch to archive files, and an administrator checks the archive files into a version control system.
