There are a number of interrelationships that must be tested to ensure affinity and fidelity between the analysis models. These interrelationships include ensuring that classes on class diagrams are associated with use cases, and that all use cases are in turn associated with at least one class on the class diagrams. Activities and actions in the activity diagrams, and events in use cases, should be associated to responsibilities on CRC cards and the class operations. Objects in activity diagrams must be associated to instances of classes. Attributes and association/aggregation relationships should be related to use case descriptions via the subject or object of an event. Actors on sequence/communication/CRUDE diagrams should be associated with actors on use case diagrams. Complex objects in activity diagrams should be associated to behavioral state machine representing the object lifecycle.

Our text does highlight that representing and establishing all these relationships and validating their affinity across the system is complex and time consuming, but criticality important to provide a solid foundation on which we can build a system.

I had to read and research a few times to try and understand the interrelationship between structural, behavior, and functional models. It looks like with both the Functional & Behavioral and the Structural & Behavioral they must align with the CRUDE matrix yet not use the same diagrams or cases. The Functional & Behavioral uses activity diagrams, use-case diagrams/descriptions. The Structural & Behavioral diagrams use the same use-case diagrams/descriptions, but they must align with CRC cards and class diagrams. The Functional & Structural model uses the same activity diagrams, use-case descriptions/diagrams that must align with the CRC cards and class diagrams. I think I got that right. Just trying to type this out seems a little confusion, but I am trying to make sense of it.
