486 objective
apply brokering to build flexible systems
Are they referring to abstract superclasses or a Object Request Broker (ORB)?

No, it's not related to Object Request Brokers (I know -- I helped review this test for IBM many moons ago). They're talking about a general design pattern of wrapping infrastructure logic (like database access) inside of a set of special-purpose classes that hide that logic from your domain model.

Thanks for the reply.
