I hava a question: In class diagram ,in mark cade book,there are only entity objects in this diagram,such as "Customer,Order,Account" and some session beans in it .but it lacks Action class and DAO class ,but they exists in my component diagram.so I want to ask wheher the DTO and value object or entity object can only exist in the class diagram. whereas the struct classes are not in the class diagram but in the component diagram.

Well .... i don't why people are silent.

I'm not a certified architect yet. But from previous postings what i read, i feel that class diagram should as generic as possible. It should be technology independant. As many people indicated, you can put a note to each CustomerProcessor / ReservationProcessor saying that in J2EE it will be implemented as a stateless / stateful session bean. I guess, no need to include DAO, controllers etc.. in class diagram. That all will go in component diagram. Make your class diagram as generic as possible. That's how i'm implementing actually.

Other ranchers, provide your inputs too.
