Detail legel of Sequence Diagrams.

[Andrew Tibets]

Hi,

I am confused, how detailed Sequence Diagrams should be.

For example, we have Sale-SaleLineItem-Product model.

- Should SD show only handling of system events? E.g. interaction of SaleUseCaseFrontController, SaleUseCaseBusinessDelegator, ServiceLocator, SaleUseCaseApplicationController, DAO, �
Like SD for Application Controller in "Core J2EE Patterns" book.

- Or should SD show more details? E.g. interaction of about components + interaction of domain classes: how Sale, SaleLineItem, Product are created. How they are linked.
Like in the "Applying UML and Patterns" Chapter 17.

Thanks a lot.
