Create and deploy an application that contains mappings, workflows, and other application objects to make the objects accessible to users that want to leverage the data outside of the Developer tool. You can deploy the application to a Data Integration Service to run the objects, or to an application archive file to save a copy of the application and deploy it to a Data Integration Service later. If you make changes to an application object in the Developer tool, you can update the deployed application. This article describes how to create, deploy, and update an application.
