Research And Implementation Of Wsi System Based On UDDI

Enterprise informationization and e-government construction has already entered a new stage in our country. Each enterprise and department develops or purchases their own application systems. As a result, these systems can't communicate, share and operate with each other. And the data is difficult to be shared. It is very urgent to integrate the massive isolated information system for enterprises at present.Along with the expansion of size, the enterprise interior has many UDDI private registration center. This paper analyzes and summarizes the traditional schemes of integrating enterprise systems, and then proposes a new solution based on the UDDI. To improve the reliability of enterprise integration system, an underlying P2P network is constructed. This paper does the following work:(1) This paper study the enterprise system integration features of traditional solutions, and design a scheme for web services integration based on the UDDI-G model. Through detailing of the UDDI module and the legacy system module, this paper build a whole framework for enterprise system integration.(2) According to the current business needs, this paper establishes an UDDI-G model and provides several UDDI registries for the web services registration and inquiry. The nodes in UDDI-G internal share and backup the data with each other. Finally, the model achieves good dynamic and robustness for integration system.(3) The underlying structure of UDDI-G is a P2P overlay network, which based on the JXTA protocols and Chord algorithm. We propose a B&P data synchronization mechanism, which can be used to design the data replication and mutual backup between UDDI nodes in the UDDI-G model.(4) On the background of university information system integration project, this paper verifies the feasibility of the web services integration scheme in practical applications, which is based on UDDI-G model. Finally, through simulating, we get good performance on business continuity and load balancing of the integration system which based on the UDDI-G model.This paper proposes a complete web services integration scheme based on UDDI, which covers the entire project development cycle. The scheme could play an important role in other systems'integration projects.
