Model-Driven Development Framework

In the model-driven framework, the model is always the source of all changes. You create a new database schema by forward engineering the model. The life cycle of a model in the model-driven Development framework can follow a path like this:

• Create the library structure (for example, Development, Test, and Production) and populate them with erwin� Data Modeler templates.
• Create the logical model in a development library.
• Promote the model to the test library when it is ready.
• Generate the schema from the test library.
• Modify the test model as required and synchronize it to the schema.
• Promote the model to the production library when it is ready.
• Publish the refreshed production model.
• Update the enterprise-wide model, if necessary.
• Incorporate changes into the development model for further changes, and repeat the process.
