On the feasibility of automatically generating data flow diagrams from ada

Introduction The recovery of high-level system documentation from source code involves two major steps, the formalization of a set of appropriate high-level graphical constructs with which to describe the target documentation, and the map­ ping of source code to these constructs. Auburn Universi­ ty’s GRASP/Ada (Graphical Representation of Algo­ rithms, Structure, and Processes for Ada) project [1] pro­ poses to define a documentation model based on the Data Flow Diagram (DFD) and design a recovery tool to pro­ duce designs conforming to this model. At present, the GRASP/Ada project is examining the GRASP/GT (Graphical Approach to the Specification of Programs/ Graphics and Text) model proposed by Morrison [2] to de­ termine its suitability for this purpose. This paper presents the current findings of this phase of the project.
