摘　　要：在分布式系统设计开发过程中,保证信息的一致性和多用户访问的并发控制是一个重要内容。为了解决LotusDomino/Notes自身的复制和保存冲突不能完全满足实际并发访问控制的需要,在分析排它锁并发控制模型的基础上,设计了基于LotusDomino/Notes的文档编辑并发控制模型,并描述其具体实现过程。实际应用表明,模型能够满足多用户并发访问控制的要求。Information consistency and concurrent control are important issues during the design and development process of distributed system. The solution of replication and document saving confliction based on Lotus Domino/Notes is not applicable to all the conditions that more than one user edit the same document at the same time. By analyzing the document editing concurrent control model based on exclusive lock, a concurrent control model based on Lotus Domino/Notes is designed. Its implementaion process is described as well .This model can avoid concurrent confliction effectively in application based on Lotus Domino/Notes.
