Abstract

Dataflow diagram is a commonly used tool of structured analysis and design techniques in specifications and design of a software system, and in analysis of an existing system as well. While automatic generating dataflow diagram saves system designers from tedious drawing and help them develop a new system, simulating dataflow diagrams provides system analysts with a dynamic graph and help them understand an existing system. CASE tools for dataflow diagrams play an important role in software engineering. Methodologies applied to the tools are dominant issues extensively evaluated by tools designers. Executable specifications with dataflow diagrams turn out an opportunity to execute graphic dataflow diagrams for systems analysts to simulate the behavior of a system. In this thesis, a syntax representation of dataflow diagram was developed, and a formal specification for dataflow diagram was established. A parser of this developed CASE tool translates the syntax representation of DFDs into their semantic representation. An interpreter of this tool then analyzes the DFDs semantic notations and builds a set of services of a system represented by the DFDs. This CASE tool can be used to simulate system behavior, check equivalence of two systems and detect deadlock. Based on its features, this tool can be used in every phase through entire software life cycle.
