分布式UDDI的数据一致性优化模型

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。

A Data Consistency Optimized Model in Distributed UDDI

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.
