On the Use of Software Development Tools in the Construction of Data Processing System Prototypes
The project at the University of East Anglia has been investigating the use of prototyping to aid the design of small data processing systems. The project springs from early AD HOC experimental work carried out in 1980 in which a programmer’s screen formatter was used to model alternative input modules for an interactive ferry ticketing system. This work was reported at the FEWIST Workshop in Aix-en-Provence in 1981 [DEARNLEY81]. More recently, the project has been considering how prototyping should be incorporated in the systems development cycle. Whilst the authors consider that prototyping can be profitably used in a number of different stages in the development cycle, they are most interested in its use in the design stage [DEARNLEY83], see Figure 1.
