摘要
集群技术是当今数据库领域的研究热点之一。以辽宁省水情数据库为例,深入讨论集群技术的理论与应用,详细介绍Share-Disk与Share-Nothing 2种集群构架,并在此基础上着重探讨Moebius技术在辽宁省水情数据库SOL Server中的应用。应用结果表明:集群技术可保证辽宁省水情数据库的高可用、数据安全、扩展性及负载均衡。
Clustering technology is a hot spot of the study on database field. This paper discusses the theory and application of cluster technology systematically, with the hydrologic information database of Liaoning Province as an example. It introduces the schemas of Share-Disk and Share-Nothing, and discusses the application of clustering technology in SOL-Server of Liaoning Province hydrologic information database as a key issue. Results shows that: the technology could ensure the high availability, data security, expansion and load balancing of hydrologic information database in Liaoning Province
