Research And Application On Service-Oriented Integrated Network Platform Model

Service-Oriented Architecture (SOA) is a component model, which associates different function units (services) in different applications with definited interface and protocol among these services. This makes it possible that services in different systems communicate with each other in a united and universal way, and can be released, discovered and invoked. Web services provide certain middlewares based on the standard interface of XML (Extensible Markup Language). Web services are self-contained, loosely coupled, standard, and highly integrated, which makes it possible to meet with the application patterns of SOA. Depending on the core technology of web services, service providers can descript the services with WSDL (Web Services Description Language), release and register services in UDDI (Universal Description, Discovery and Integration) registry. Service requesters can search services that they need in UDDI, bind and invoke them with SOAP (Simple Object Access Protocol).A Service-Oriented Intregrated Network Platform (SOINP) Model based on web service is brought out after which is living to analyze the service-oriented architecture (SOA) and the core technology of web services. SOINP is a platform developed, deployed and managed by web services, which can provide services for a large organization from inside and outside view through different ways. SOINP uses a layered architecture. It is divided into five layers. From bottom to top are transport layer, service communication protocol layer, service description layer, service layer and business process layer, and plus a service registry. Moreover, requirements of policy, security, transaction and management are penetrated in SOINP. In SOINP model, services can be reused in different application. The realized model of SOINP can be divided into three parts, which contains the common client as the service requester, the UDDI server as the service registry and the web services runtime environment as the service provider.WPMS (Web Purchase Management System), is analysed and designed by SO (Service-Oriented) and OO (Object-Oriented) method. In the development of this system, the above-mentioned model of SOINP is pruned to adapt in use in the internal system of government, and achieve a portion of this model in realization.
