摘　　要：分析了现有的分布式并发控制机制的不足,提出一种基于有序相容性多粒度的多版本两阶段封锁协议,并对其正确性进行了证明。分析表明,该协议可有效提高协作设计事务的并发度,比较适合于开放式的协同设计环境。The defects of current distributed concurrency control protocol were analyzed. Then, a multi-version twophrase locking protocol was proposed based on ordered sharing, and the correctness of this protocol was proofed. The analysis results show that the protocol can enhance the concurrency of cooperative design transaction and is suitable for open cooperative design environment.
