In this paper, the authors present an approach that combines the DFD with the UML diagrams. DFD is a structured approach which provides the functional view of the system whereas UML is an object oriented approach provides the structural view of the embedded system. Structured methods are very commonly used by the developers and if there is need to expand the functionality of the systems then object oriented approach is used which is very useful. So the combination of both approaches will be beneficial for the developers. For this they merge data flow diagrams (major tool of structured approach) with unified modeling language diagrams (use-case & class diagrams).
