Chapter 12 Comparing and Merging Models

Comparing models

PowerDesigner allows you to compare the content of two models or two resources of the same type. The Comparison feature highlights all the differences that exist between them.

You can compare the following items:

Models CDM, PDM, OOM, BPM, XSM, ILM, RQM and FEM.

Resources DBMS, object languages, process languages, XML languages, extended model definitions, report languages.

For more information on the comparison of resources, see "Comparing and merging resource files" in "The Resource Editor" chapter.

You use the comparison feature to:

• Follow up evolutions in models or resources manipulated by different development teams
• Evaluate the differences that exist between the models or resources before merging them
