Physical Models

Two levels of physical models exist for an implementation project:

• Transformation model
• DBMS model

The physical models capture all of the information that data architects and database administrators require to implement a logical model as a database system. The Transformation model is also a project data model that describes a portion of an overall data structure supported by a single automation effort. Individual projects within a business area are supported, allowing the modeler to separate a larger area model into submodels, or subject areas. Subject areas can be developed, reported on, and generated to the database in isolation from the area model and other subject areas in the model.
