The Reaserch And Implementation Of Registry Center For Web Service

As a new distributed computing technology, Web Services attracts attention of industry since it appeared in 2001 with many advantages. Now some international groups and organizations are founded to research and constitute various protocols and specifications to specify its development. A critical problem in Web Services is how to discover, describe and integrate services in open networks environment.We have designed a registry centre based on UDDI (Universal Description Discovery and Integration) to solve this problem.There are some problem on the public registry centre, so we use Web service and private UDDI registry center build a theory model of a resolution. By providing Web service for these heterogeneous applications and registrying these applications on the UDDI registry centre, we can build stronger applications based on those Web services in a standard. In the private registration centre, the establishment of the Web services database tables is be implementation with UDDI standard features in the data structure, the use of information mechanism called SOAP (Simple Object Access Protocol) interface with the registry centre, and in accordance with the only key element in the service, Business-related information is also available bundled, according to the information available database table, could find service described file address, and service calls are implementation.Registration centre adopts the three-tier architecture, and it is divided into four modules- the UDDIProxy, registration module, inquire module and database connecting module. It puts forward a realizable method of using Web services and UDDI registry center to integrate applications within enterprise and between enterprises and its partners. By building such an open, global, service-oriented architecture, the heterogeneous application can communicate in standard method.
