System-Driven Model Framework

In the system-driven framework, there is an established information system from which you can reverse engineer database tables. The life cycle of a model in the system-driven Development framework can follow a path as described below:

• Create the library structure (for example, Reverse Eng, Test, Production). You do not require erwin� Data Modeler templates because you do not create models from scratch.
• Reverse engineer the model from the information system into the designated library.
• Enhance the model with logical information and input from analysts.
• Update the model to reflect changes in the physical schema.
• Create a version of the model.
• Synchronize the schema and the model using Complete Compare.
• Publish the model.
• Repeat the last three steps as the system is modified.
