How does a use case report Differ from a Data Flow Diagram (DFD)?

To answer briefly:



A use case models interactions between actors and "Use Cases" A Use case is a functionality of a system that provides something useful to the actor.



For example, a use case might be a high school student checking out a book from the library system. The Actor is the High School student, and the use case is Checking out a book.



A DFD models the flow of information through a system. It provides a bit more detail of the functionality of the system than does a Use Case.



Use cases don't look at how a system does what it does, it just points out what functionalities are provided to actors.



Hope this helps. If it doesn't, I'd suggest finding some UML resources on the internet, there are tons of them. Try google.

How come we saw the exact same question (http://www.jguru.com/forums/view.jsp?EID=1069447) just the other day (which I already answered), posted under a different userid? Are you both working on the same homework?
