Remember: I haven�t gotten my results. I don�t know whether I have passed in phases II and III. Maybe everything I am telling you is wrong.
Do you agree that this is a High-level architectural design? You do not have all the requirements and there are many shadow areas in the assignment.
If you are an architect, you are not expect to produce the detailed system design. This is a developer�s (or Systems Analyst) Job. So, how would you know all the necessary methods and their signature? How can you be sure that the interfaces of the classes are correct?
The important thing is to produce an overall architectural design that uses J2EE and satisfies the requirements for both clients (Web Customers and Travel Agents).
I have read many messages here, in the forum, and discussed with many people that has earned the certification. Some people have produced fine-grained detailed diagrams and have passed. But much more people have followed Mark Cade�s designs and produced simple diagrams, and they have passed too.
So, I decided to produce a minimalyst proposal, using plain english as messages.
I may be wrong. But producing detailed diagrams does not make sense for me as an architect (what I really am). If I am wrong, ok. I will modify my assignment and pay the ressubmition again.
If you are still not sure, read Mark Cade�s sample.
