This work proposes a framework for transforming data flow diagrams (DFD) into UML artifacts. The framework is a systematic step-by-step approach that enables systems analysts and designers to achieve the transformation. Many existing legacy systems were designed using structured analysis and design methodology (SAD). Some of these legacy systems need to be re-designed and re produced using object-oriented analysis and design (OOAD) method to make the system more maintainable. We show that a transformation should be done at three abstraction levels. We have demonstrated the applicability of our framework with a simple case study.
