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。
UDDI registry is essentially a database that stores the registration information of Web services. In order to solve the problem of data inconsistency in the architecture of distributed storage and retrieval, a data consistency optimization model of distributed UDDI is proposed. Firstly, the core data model of distributed UDDI and UDDI is analyzed, and the problem of heterogeneous data sources in distributed environment is analyzed. On this basis, the consistency of data is analyzed, and the reachability matrix between UDDI node and data model is constructed. Finally, the consistent data storage strategy of distributed UDDI is studied. The optimization model can effectively reduce the storage redundancy and retrieval of network bandwidth consumption.
