A use case is an OO tool used to show the interaction between behavioural elements of a system (use cases) and elements of the 'outside world' (actors). Use cases are generally used in the requirements analysis stage. A DFD is a tool dating back to pre-OO days and is used to show the flow of information within a system. It can be used as part of the requirements analysis stage (to illustrate existing flows) or as part of the logical or physical design stages to illustrate planned flows.
