摘要
本文提出了一种适用于分布式数据库的基于时间戮的并发控制算法和基于封锁技术的并发控制算法相结合的算法;确定了结合的较佳时机以及如何进行转换;并提出了采用标定优先级的方法来缩减用于全局死锁检测的冲突图的规模。
A new concurrency algorithm fitted to distributed database systems isproposed in this paper,Which combines the optimun concurrency algorithm basedonthe timestamp,with the concurrency algorithm based on locks;Using this algorithm,we can know the chance for combining and how to exchange,and the use of prece-dences enables us to reduce the size of the conflict graph for global deadlock detections.
