Using diagrams to develop and maintain models

During the course of application development, there are times when it may be necessary to migrate data from one system technology to another. In the simplest of cases, the structure of the given object may require only minimal changes such as data type conversions. Using ODI diagrams to perform these basic functions is an easy way to accomplish these tasks.

Getting ready

In order to follow this recipe, it is assumed that the reader has performed the preliminary installation steps outlined in the Preface. If these steps were done correctly, the reader should already have a DEMO_FILE data model containing two flat file data stores and a DEMO_TRG model that defines objects found in the DEMO_TRG database schema.

Now, let's suppose that we wish to quickly build an application that migrates data from a flat file into a database table. What we will do in this recipe is to use an ODI diagram to automatically construct a database data store based upon...
