I think Business Domain Object is the term that Business Analysist uses to modelize. In Java design, it should be transformed into Value Object/Transfer Object or (entity EJB). I prefer VO/TO 'cause it is more clear, and easy to understand (Object that stores data, that glues layers, components.

How do you think?

In fact, the term VO/TO is defined by Sun. I worked for IBM, they said BusinessObject, DataObject

When designing your class diagram, I should try to focus on object oriented analysis and design techniques (OOAD). At the analysis level, do not include any architectural patterns in the diagram. They should only define business entities and contraints.

At the design level, you can put some extra classes like TO/VO's. To be honest with you, for the exam pourposes, it do not require those patterns. Try to keep your class diagram technology neutral, regardless the business components like fa´┐Żades or business objects.
