“Transforming data flow diagram to use case diagram”

In this paper we present an approach that transforms the DFD to the Use Case diagram of UML. DFD is a structured approach which provides the functional view of the system whereas Use Case diagram is an object oriented approach provides the functional view of the system under consideration. 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 transformation of one approach to the other will be beneficial for the developers. For this we present an approach that will transform Data Flow Diagrams (Major tool of Structured Approach) with Use case diagram.
