Abstract This paper describes a model of modular system for Rapid Application Development of Web-based Information Systems (RADWIS). The existing modular systems on technology, framework and platform level does not fully solve the problems of functionality reuse, rapid application development and balance between the complexity, size and functionality. The proposed modular system addresses these problems in a new way. The current work fills the gap between the modular systems on the framework and platform level. The model uses flexible, reusable modules, which can be built with different technologies. They are installable and shareable with the standard dependency manager of the technology and can communicate using web services. The modules use NoSQL approaches in SQL databases. A workflow engine module, based on the Petri Nets theory, allows a graphical and formal mathematical solution for a wide variety of problems.

SummaryIn the development of hospital information systems it is difficult to describe data and activities simultaneously and equivalently. Most of the methods used so far are only suitable for either data structures or functional modeling. In particular, it is not possible to comprehend the functional interdependence of hospital procedures.In this paper it is shown that Petri Nets are well suited for the development of complex software systems. Their exceptional properties are, on the one hand, the simulative capacities which allow to visualize interlinked and interdependent procedures of the real world. On the other hand, it is pointed out that Petri Nets comply with the demands of software engineering. In order to make these characteristics clear, two models from real developments are used: Firstly the organizational model of a small hospital and secondly the model of the data entry in the follow-up of tumor patients.
