摘要： 就网格数据库的研究现状进行了介绍,并针对某企业的实际应用论述了如何基于OGSA DAI采用发布/订阅模式,实现网格数据库间的实时数据复制。就其关键技术———分片处理策略和体系结构等进行了论述。经测试基于发布/订阅的复制模式比基于Oracle数据链路的Pull方式的数据复制模式具有更高的效率和更好的实时性。

关键词: 数据复制, 发布/订阅, OGSA-DAI, 网格数据库, 数据分片

Abstract: The work relevant to the Grid Database was introduced. According to one practical application of an enterprise, author discussed the design and implementation of real-time data replicate system in Grid Databases, which based on OGSA-DAI and publish/subscribe model. The overall architecture and the key technologies of data partition strategy were presented. Test results demonstrate that the model that bases on the Publish/Subscribe has higher efficiency and good real time property against the pull-method model that bases on the Oracle data linkage.

Key words: data replicate, publish/subscribe, OGSA-DAI, grid database, data partition
