Abstract

The Unified Modeling Language (UML) has become the de facto standard for modeling the architecture and behavior of an object-oriented software system. However, many legacy systems have been documented using non-object structured analysis and structured design. This paper proposes a framework to convert a data flow diagram and an entity relationship diagram into UML artifact, including a use case diagram, sequence diagrams, and a class diagram. The new UML model can be used by analysts or computer aided software engineering tools to implement new object-oriented system. The set of rules for transformation is tested on a structured analysis and design example
