Lesson 3.6: Cross-reference class and sequence diagrams
Run a Microsoft Word report to verify that every message modeled between objects on a sequence diagram has a corresponding association between the instantiated classes, (and vice versa).
If you were designing your own system, you might have hundreds of Sequence diagrams detailing the scenarios of your system. To verify that these correlations have been made, you can use an automated SA/Word report provided by System Architect.
Note You must have Microsoft Word installed on your local machine to run this report.
1 Select Reports > Word Reports > Object Model Reports > Sequence Class Xref Report. Microsoft Word should automatically run, and load a special Microsoft Visual Basic Applications macro that has been installed into your Word template directory upon installation of System Architect. The UML Sequence Diagram/Class Diagram Interrelationships Report should show up in your Word document.
2 At the end of the report, you should see two informative tables - Messages with no Association on Any Class Diagram, and Associations with no Events on Any Sequence Diagram.
The first table tells us is that you have not modeled an association between Reception and Customer on the class diagram, even though a Sequence diagram tells us that there is a relationship between corresponding objects that instantiate them. The second table tells us you modeled an association on the class diagram between Customer and Reservation, but no such relationship exists between any two instantiating objects on any Sequence diagram.
In your own project, you would now go back and make appropriate changes to your models to achieve consistency.
3 Close the word report and select No when asked to save the document.
