Cedric's example is applicable when you have one to many bi-directional
relationship for Person to Address. You can have one to many uni-directional
relationship as well. In that case you need not declare CMR field in the
Address bean for Person, and your Address bean will not have abstract
methods (getPerson/setPerson)to access the CMR field Person.
