Chapter 10 Comparing and Merging Models

Merging two models

You can launch a merge of your model with another model of the same type at any time.

To merge two models:

1. Select Tools→Merge Models to open the Select Models to Merge dialog box.
   
   The current model is displayed in the To field.
2. Select a model to compare in the From list. Only models of the same type in the workspace are available for merging.
   
   
   
      DBMS and Language
   If you want to merge physical data models, you have to select two models with the same DBMS. If you want to merge object oriented models, you have to select two models with the same language.
   
   
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 and possible merging. For more information, see Comparison options.
4. Click OK.
   
   The Merge Models window opens.
