A method and a tool for rapid prototyping of large-scale business information systems

This paper presents a method and concepts of a supporting tool for rapid prototyping of large-scale business information systems. Our method is based on the following guidelines: (1) small team of highly skilled members with combined skills, (2) prototypebased development of subsystems and the system as a whole, (3) brainstorming sessions always involving system analysts, database and application designers, and user representatives (if needed), and (4) application generator providing for efficient prototype development by maximum automation of all design phases. The also presented application generator (AppGen) is based on standardization of functional and visual characteristics of an application, a library of high-level, coarse-grained components, and a set of rules for modelto-application mapping enabling automatic application reconfiguration in case of changes in the data model.
