Abstract—In order to improve the quality of healthcare services, large-scale medical information systems should be integrated with adaptability in response to the changing medical environment. In this paper, we propose a requirement-driven architecture for healthcare information systems that will be able to respond to new requirements. 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 driving factor of our system. Finally, we propose an integration framework for data sharing amongst different hospital organizations and also present the HL7 based virtual database to realize the data integration. Our research makes a contribution to the design and implementation of the architecture of healthcare systems which can adapt to the changing medical environment.
