PowerDesigner provides powerful tools for comparing models and merging them.
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 review evolutions in models or resources manipulated by different development teams or to evaluate the differences that exist between the models or resources before merging them.
Merging Models
You can merge the content of two PowerDesigner models or two resource files of the same type at any time.
Excluding Objects and Properties from a Compare or Merge
You can control what types of objects will appear in the comparison or merge window along with the attributes and collections to compare for them through the Comparison Options dialog. By default, all objects and properties are selected.
Filtering Objects and Changes During a Compare or Merge
Click the arrow next to the Filter tool in the Compare or Merge window to select a filter to apply to the object trees and display only certain types of changes, conflicts or, any combination thereof.
Repairing or Breaking Links Between Objects
Sometimes, when an object has been renamed or modified outside PowerDesigner, its link with the corresponding object in another model may be lost, and the two objects are shown independently, with a creation and a suppression in each model tree. You can manually repair the link between the objects or, in rare cases, break a link between objects that you do not want to compare or merge.
