摘　　要：对基于时间戳的分布式事务并发控制策略进行了介绍,分析了存在的问题,并在其基础上提出了一种改进的并发控制策略,弥补了传统策略容易造成事务回滚,时间戳信息需要占用额外存储空间等不足之处,通过实验数据证明,改进后的策略能够有效减少事务的回滚,节省存储空间,而且实现较为简单,具有一定的应用价值。This paper introduces concurrency control strategy of distributed transaction based on timestamp ordering, analyzes existed problems, and presents a improved concurrency control strategy in order to fix up the deficiencies in traditional strategy such as frequently rolling back, additional space required etc. Proved by the experiments, the improved strategy can reduce times of roiling back effectively, and consume less space. Furthermore, the improved strategy is easy to be carried out, has kind of value for applications.
