Comparing Models

You can compare the content of two PowerDesigner models or two resource files of the same type at any time.

You may want to compare models or resource files 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

Note: For more information about the comparison of resource files, see "Comparing Resource Files" in the Resource Files and the Public Metamodel chapter of the Customizing and Extending PowerDesigner manual.
  1. Select Tools > Compare Models to open the Select Models to Compare dialog box.

    The current model is displayed in the Model 2 field.

  2. Select a model to compare in the Model 1 list. Only models of the same type in the workspace are available for comparison.


  3. [optional] Click the Options button to open the Comparison Options window and specify which objects and properties you want to include in the comparison. For more information, see Comparison options.
  4. Click OK to open the Compare Models window, which displays the objects contained within the models or resource files in a tree format, and highlights the differences between them. See Analyzing differences in the Compare Models window. You can apply a filter to simplify the list of differences (see Filtering Changes in the Compare and Merge Windows).
