If I'm using the DAOFactory pattern in my system, do I have to show these classes (DAOFactory, DAOXXImpl, etc) in the component and sequence diagram? Cades book shows that the ServiceLocator pattern is being used and this class is shown in the Sequence / component.
I didn't show DAOFactory in any diagrams. Apparently, it makes the diagram very messy. So I just mentioned in the description of class diagram and component diagram. I'm still waiting for the final result. This may cost the points.
