Design and implementation of Interoperable Medical Information System based on SOA

Interoperability among healthcare information systems is one of the most challenging problems in healthcare domain. In this paper, we propose a structure of interoperable medical information system based on SOA (service-oriented architecture) and Web 2.0 under the framework of regional health information network. Various components are described in detail, including authentication, data access, and services management and so on. Services for medical information getting are registered and published by the system; users then access the system to search and fetch demanded services and value-added applications. All of the heterogeneous and distributed data and applications are converted to independent services according to international standards. As a result of the use of SOA, the system is levels clearly demarcated with good universality and maintainability.
