....the problem. Functional approaches are based on the concept of structured analysis and functional decomposition of the problem achieved through a top down refinement process. Data flow, more recently evolving in Petri Nets graphical languages, is the most representative technique in this area [5, 6, 7, 8, 9, 10]. However these approaches induce an architecture which is too heavily dependent on the functional aspects of the problem. On the one hand there is no direct relationship between the resulting modules and the physical elements of the reality, on the other hand, the control architecture results in ....

Within the business development environment, data flow diagrams (DFDs) Gane and Sarson, 1979; DeMarco, 1978) are widely employed to depict processing requirements (Tse and Pong, 1989) Given that DFDs are used in order to reduce system complexity (Keuffel, 1991) assessment of this representation, with the measures defined in Table 4, should provide quantitative and objective indications of relative ....

....by CNR under grant n. 89.00039.69, and n. 89.00532.67. M. Cavalotto is working at the Politecnico with a fellowship from the Chamber of Commerce of Turin 1 1 Introduction During the past ten years the software life cycle has become a well worn issue in the framework of structured analysis (SA) [10, 23, 11]. As a result functional oriented methodologies have been refined and a variety of supporting CASE tools have been developed and are available on the market. We refer to those tools based on SADT[23] data flow[29] Petri Net[21, 5, 25] and so on. Starting from the original waterfall model, ....
