Chapter 7 Linking and Synchronizing Models in PowerDesigner

Model generation

You can generate a model from another model of the same type or from another type.

Model generation is used to link models together provided the Save Generation Dependencies option is selected in the Detail tab of the generation dialog box. This option creates the generation link itself and makes it possible to keep track of the identity of the origin of each generated object.

For example, you generate a PDM from a CDM when you want to start implementing the physical aspect of a conceptual model. The generation link allows you to iterate CDM to PDM generations preserving generation choices over the process.

Model generation allows you to:

• Generate a new model that will contain objects translated from the source mode.
• Update a model to impact changes.

For more information on merging two models, see the "Comparing and Merging Models" chapter.
