Application of the component paradigm for analysis and design of advanced health system architectures

Abstract

Based on the component paradigm for software engineering as well as on a consideration of common middleware approaches for health information systems, a generic component model has been developed supporting analysis, design, implementation and harmonisation of such complex systems. Using methods like abstract automatons and the Unified Modelling Language (UML), it could be shown that such components enable the modelling of real-world systems at different levels of abstractions and granularity, so reflecting different views on the same system in a generic and consistent way. Therefore, not only programs and technologies could be modelled, but also business processes, organisational frameworks or security issues as done successfully within the framework of several European projects.
