摘　　要：讨论分布式数据库中的并发控制问题,结合相关的理论,设计了一个多副本的并发控制模型。运用分布式并发控制的主副本算法,使用MTS/COM+技术,对并发控制机制进行了研究和基本实现。最终在客户端实现了针对分布式数据库多副本的读取和更新操作,达到更新一致性,具有较高的执行效率。This article ventures to probe into the problem of concurrency control in a distributed database, and to offer a design of multi - copy concurrency control model with the support of relevant theories. We basically carry out the concurrency control mechanism in the research of it by means of the primary copy algorithms of the distributed concurrency control, and by using the technology of MTS/COM ＋ . We realize the refreshing agreement in the operation of fetching and refreshing of multi - copy distributed database on the client - side, with high execution efficiency.
