Informational Model Framework

In the Informational Model framework, erwin Data Modeler Workgroup Edition contains logical-only models, enterprise-wide models, or standards and sample models. There is no forward engineering with the intent of using the schema. The life cycle of a model in the Informational Model framework can follow a path as described below:

• Create the library structure and populate them with templates.
• Develop the initial model. Use reverse engineering and model new components as required.
• Publish the initial model to the appropriate parties for modification and refinement.
• Get approval, and then version the model.
• Publish the approved model.
• Update and publish models as the enterprise model evolves.
