Based On Soa Regional Health Information Platform

At the present time, most enterprises and institutions established management information system. The cross-cutting of different types of operating systems, application software, system software and application infrastructure don't make these systems reusable, so the reusability of software and system integration in software development become increasingly important.Service-oriented architecture (SOA for short) is a component model. The features of loose couple and platform-independent, which allows enterprises can add new services or upgrade existing services by following a modular approach, to meet new business requirements, and adapt to business changes.After analyzing the business requirements analysis of regional health information platform in this thesis, the regional health information platform based on SOA is analyzed and designed. This paper achieve all function units of the platform and by Web Service, provide internal business interfaces which can be called by external system. Then, external systems call the interfaces to achieve system interoperability and integration.This paper is introduced as follows:(1)Theoretical knowledge related to SOA and its realization are studied in this paper.(2)The regional health information platform and its core - the residents health records - are briefly described, through the analysis of information sources, understand the specific users of the platform, and complete business requirements analysis of all areas, and design each function module.(3)According to the functional requirements, the presentation layer, business layer and data persistence layer are designed in details.(4)This paper has achieved the service interface for external systems and interoperability between the systems through using Web Service technology.By Web Service technology, SOA has been used in the regional health information platform, which effectively solve information sharing and collaboration of health service institutions within the region and improve work efficiency.
