Chapter 6 Generating a Conceptual Data Model from an Object-Oriented Model

Generating a CDM from a package

To generate a CDM from a package, select the package name from the Select Location dropdown listbox at the top of the page.

To generate CDM from a sub-package, select the Sub-Packages Included icon next to the Selection Location dropdown listbox, and then select a sub-package from the dropdown listbox.

8Select class checkboxes for each entity that you want to generate. or

Clear class checkboxes for each entity that you do not want to generate

9Click OK.

If you selected the Preserve Modifications checkbox, the Merge Models window appears.

If you cleared the Preserve Modifications checkbox, the updated CDM appears in the diagram window.

Merging models

The Merge Models dialog box shows the newly generated CDM in the Source Model pane, and the existing CDM in the Target Model pane. You can select or clear object check boxes in the Source Model pane for CDM objects that you want to be included or deleted in the target model.

∃For more information on merging models, see the chapter Comparing and Merging Models in the PowerDesigner General Features Guide.
