The Physical Data Model
The Physical Data Model (PDM) depicts the designed system as targeted to a specific database.
You can generate a PDM from any ER model or subject area diagram. Conversely, you can generate an ER diagram from a PDM.
You can generate schema to a database or DDL; import the structure of an existing database to create a physical data model, or synchronize a data model to DDL, a database or another PDM.
