RPT: a CASE environment supporting the rapid prototyping approach to software development

The result of research in automating the software development process-a CASE environment named the Rapid Prototyping Tool (RPT)- is described. It allows the analyst to describe both the statical model and the dynamical model by means of the same conceptual tool-modified dataflow diagrams (DFDs). Thus, no transformation needs to be performed when proceeding from the description of a statical model to a dynamical model. This provides simple and fast management of the development process, although it contains many iterations. The control algorithm is described implicitly by means of activation conditions of each system process. It is not necessary to describe all system states and events or the whole control algorithm of a system
