Research And Implementation Of Service Library Registry Center In E-Government Platform Based On SOA

Along with the mature of the related standards and technology of SOA, more and more users show great interests on SOA applications. Constructing E-Government based on SOA attract wide attention.In E-Government based on SOA, as the management tool, the construction of service library deal with how to manage, control and monitor a large amount of services. UDDI service library registry center is the infrastructure of service library construction,which is the key important point of service library directory architecture construction. Therefore, this thesis put focus on the design and implementation of service library registry center in E-government platform. The main work includes:First, this thesis reviews the history of E-Government and the problem, and introduces the origin, notion, characteristics and advantages of SOA. Moreover, we analyze the related Web technology, especially the research and application situation of service library and registry center.Second, according to application characteristic of service library in E-Government platform, service library general framework is designed based on state-of-the-art technical payoffs of SOA and Web Services in China and abroad.In the course of designing,we assure stability and extendibility of general framework by keeping to technical standard ,using service resources and reusable component resources,supporting based on service management platform,centering on registry center of service library and directory, showing service portal, emphasizing managing mechanism.Next, UDDI registry center of service library is introduced, which is the main work of this thesis. Based on deep analysis of UDDI technical standard and the general architecture of service library, we make system design of UDDI registry center of service library in general framework. At the same time ,we complete system function design , module design and main flow design.At last, the registry center of service library is implemented and developed. Through UDDI registry center of service library, developer and enterprise user can find, publish and bind service.In order to verify the validity of the registry center proposed in this thesis, we apply it into E-government portal website, such as The Portal of Beijing Civil Servant. It well satisifies users of all levels.
