分布式UDDI的数据一致性优化模型

摘要

UDDI注册中心本质上是一个存储着Web服务注册信息的数据库,针对分布式存储与检索体系架构中出现的数据不一致性的问题,提出了一种分布式UDDI的数据一致性优化模型.首先分析了分布式UDDI及UDDI的核心数据模型,以及在分布式环境下的异构数据源问题.在此基础上,分析了数据的一致性问题,构建了UDDI节点—数据模型间的可达性矩阵,最后研究了分布式UDDI的一致性数据存储策略.该优化模型能有效减少存储冗余和检索网络带宽的消耗.%Essentially speaking, UDDI registry center is a data of Web service registration information. To solve the problems of data inconsistency in distributed storage and search architecture, the paper brings forward a data consistency optimized model in distributed UDDI. Firstly,the paper analizes not only core data model but also isomerous data source problem in distributed surroundings. After that, data consistency problem is analyzed, and UDDI node-data model accessible matrixes are constructed. Finally, the consistency storage strategy in distributed UDDI is studied. The optimized model can reduce the storage redundancy and search bandwidth consumption.
