Part II: Using DAOs in Class Diagram & Sequence Diagram

[Allexicus Kernikus]

I've been using Cade & Sheil SCEA Study Guide as a reference.

Their example class diagram does not include anything outside of the domain model - also all DAOs are not referenced within the class diagram, only in the component diagram.

Since the sequence diagrams should not use classes not referenced within the class diagram, I have been wondering if they should reference the necessary DAOs etc. If not, the sequence diagrams will have very few actors (front end, controller & some arbitrary manager).

My question: should classes from the integration tier (e.g. DAOs) be referenced within class diagrams? And/or should they be referenced within sequence diagrams?

Many thanks in advance for your support - Alex

Alex,
I think the integration classes should absolutely be in the class diagram. For mine, I have to class diagrams because there were too many classes to read easily in one.

There's an FAQ page that covers things like this in Cade/Sheil. I've added your question to it and linked to this thread.
