Physical Models

There are also two levels of physical models for an implementation project: the Transformation Model and the DBMS Model. The physical models capture all of the information that systems developers need to understand and 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 intended for support by a single automation effort. Individual projects within a business area are supported, allowing the modeler to separate a larger area model into submodels, called 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.
