Chapter 12 Generating Other Models from an OOM

Generating a Physical Data Model from an Object-Oriented Model

You may want to go from a class diagram of an Object-Oriented Model (OOM) to a Physical Data Model (PDM) because the design of your system in the OOM can be directly used by the database you want to work with. The advantage of this process is to model the objects in the world they live in and, through the generation, to automate the translation to tables and fields in the database.

When you generate a PDM from an OOM, PowerDesigner translates OOM objects and data types to PDM objects and data types supported by the current Database Management System (DBMS). The current object language of an OOM has no effect on the generation to a PDM.
