ModelRight can compare your Model with another Model to show and resolve differences between the two. You can export differences from the current/source Model to the target Model to make the target Model more like the source Model, or you could import differences to make the source Model more like the target Model. The Compare with Model wizard is used for both purposes: |
How to Compare your Model with another Model:
1.Select Model > Compare with Model from the menu 
, or select 
from the Modeling Tasks section of the Shortcut Toolbar to start the Compare with Model wizard.
2. In the first wizard page you can specify the target File/Model that you want to compare with. You can also define the type of objects and properties that you want to compare:
•File: enter or Browse for the file that contains the target Model that you want to compare your current/source Model with
•Compare Filter: specify the types of objects and properties that you want to compare.
•Match Using Owner - after ModelRight loads the target Model, it needs to match up Tables (and Views, etc...) in the source Model with Tables in the target Model. If this option is selected, then a Table's owner must match as well as the Table's name before ModelRight will automatically match them.
•Match Case Sensitive - if selected, then the case of the names of objects must match before ModelRight will match the objects.
5. This wizard page shows the differences between your source and target Models. ModelRight will save any changes that you make to the target Model if you click Finish.
Toolbar Buttons
- export or import a difference. Use the import button 
to import an object(s) or property into your current Model. When you import an object/property, the action is performed immediately and the comparison trees will be updated immediately with the result(s). Of course you can use the Undo/Redo toolbar buttons 
that are on the page to undo/redo any changes.
Use the export button 
to export any source Model object or property to the target Model. If you export an object/property, the action is performed immediately on the target Model and the comparison tree updated to reflect the result.
- go to the previous/next difference
- undo/redo changes that you made
- delete an unmatched object on the Model or database side
- manually match or un-match objects. If ModelRight doesn't automatically match two objects that should be matched (probably because their differences in their names), then you can do so manually. Simply select one of the objects, hit the match toolbar button 
and select the other object that you want to match. To un-match tow matched objects, select the matched items and hit the un-match toolbar button 
.
Only Show Differences - if selected, then items that match and are equal are not displayed.
Show Dependencies - shows all the referenced objects that an object depends on. In some cases, importing/exporting an object's differences will not fully resolve a difference unless its referenced objects are first imported/exported. Selecting this option will cause unresolved dependencies to be displayed under objects in the tree so that you have a visual cue to help you determine what needs to be imported/exported to resolve differences.
