- Did you show attributes and ops in the class diagram?
I recommend showing *all* attributes and ops that are involved in business transactions and process flow. As the assignment mentions, you don't have to show other insiginficant attributes and you can safely ignore showing getters and setters.
- How many classes do you have?
It greatly depends on your solution and how you count them. Some people have chosen to show classes outside the scope of the solution( such as standard
Java classes ) for the sake of clarity whereas others have not included them to avoid clutter. Same is true for showing/hiding Home, Remote and Bean implementation classes for every
EJB.
- Have you changed the BDM?
The keyword is not change but
extend. As the name suggests, it is the
Business Domain Model that represents very high level relationships between domain level entities. Normally problem analysis yields more classes and refines the BDM. Note that the final design model cannot contradict( omit, render vague or nullify ) any association and cardinality specified in the BDM.
- Have you consolidated some BDM classes?
See my response above.
