Modeling Requirement Driven Architecture of Adaptive Healthcare System Based on Semiotics
Yang Hongqiao, Weizi Li · 2009
In order to improve the quality of healthcare services, the integrated large-scale medical information system is needed to adapt to the changing medical environment. In this paper, we propose a requirement driven architecture of healthcare information system with hierarchical architecture. The system operates through the mapping mechanism between these layers and thus can organize functions dynamically adapting to user's requirement. Furthermore, we introduce the organizational semiotics methods to capture and analyze user's requirement through ontology chart and norms. Based on these results, the structure of user's requirement pattern(URP) is established as the driven factor of our system. Our research makes a contribution to design architecture of healthcare system which can adapt to the changing medical environment.
