Transformation from Data Flow Diagram to UML2.0 activity diagram

Model transformations are frequently applied in business process modeling to bridge between languages on a different level of abstraction and formality This paper proposes a model transformation from Data Flow Diagrams (DFD) which have been used widely in structure requirement analysis phase to UML Activity Diagrams (UML-AD) which have been used widely in various phases of Object Oriented Development Method. First, we analyze the elements in DFD and the elements in UML-AD that can be transformed from DFD. Based on the corresponding relationships between DFD and UML-AD, the transformation rules from DFD to UML-AD are proposed. Finally, a case of textbook purchase and sale system is used to verify the feasibility and effectiveness. According to the proposed method, the business process models that are written by DFD can be easily transformed into the business process modes that are written by UM-AD, which realizes the interoperability between DFD and UML.
