Similarity syntax rules between DFD and UML diagrams

Abstract

Today, individual and society relies on innovative software systems. This situation needed software engineering to produce dependable and trustworthy systems economically and rapidly. During analysis and design, requirements specification can be documented using two (2) mostly methodologies which are SDLC (software development life cycle) and OOSAD (object-oriented system analysis and design). In SDLC, DFD (data flow diagram) specification is used, meanwhile UML (unified modelling language) specification is used for the object-oriented approach. Nowadays, there is an intensive research for model transformation, integrating and merging from structured to object-oriented approach. Most researches are concentrated on converting the existing DFD to UML diagram. In the end, they produced a new UML diagram as a design material and the implementation of new systems. It is also serves as a documentation for the upcoming development of new systems. This paper proposes a framework which is acquired from the syntax rules for DFD and UML. Established along the similarity methods, this paper will define the syntax rules of DFD Level 0, DFD Level 1, UML Use Case Diagram and Sequence Diagram. Then, the method is tested with the case study of DFD and UML diagrams. Furthermore, the factors involved in the similarities are found. And so, the similarity can be utilized to generate requirements specification from DFD to UML Diagram.
