Since the code differs a bit from the diagram on page 63, I produced an UML diagram and a database diagram.
I omitted the classes UserId, CustomerLocation, Customer, they have nothing to do with the sample.

Christian, if you like, you may put them in the CVS.

Hi Klauslz,

Your work clear many of my questions on caveatEmptor.
But I have some questions on your UML notation.

What is the meaning for the Labels on association arcs (e.g. +biddeditem, -default, billingData)?

Thank you very much!

Best Regards,
Chrono

An association has a name (optional) and the assocation ends can be named as roles. If there are two associations of different meaning between two entitites, they must get either different association names or different role names.
