Chapter 8 Managing Objects
Extended objects and links are additional objects that can be added in any kind of model to let you design specific business needs or concepts that are not supported by PowerDesigner standard objects.
Extended objects and links exist by default in the free model; they can also be added to any other model to provide greater design flexibility.
For more information on the free model, see section Using the Free Model in chapter Managing Models.
For example, you can use extended objects in a PDM to design database specific objects that do not exist by default in the model. These objects are not generated or reverse engineered by default, but you can add generated files in order to define extended generation. You could also use extended objects to design UDDI related data in an OOM.
