分布数据管理的一种并发控制算法

A Concurrent Control Algorithm of Distributed Data Management

提出一种用于分布数据管理的基于锁定的并发控制算法。该算法对冲突处理无需在全部分布站点程序调度器间进行通讯，仅需在冲突初始站点和所有参予站点间进行信息交换；又由于在冲突发生时通过使用时间戳来建立一个执行顺序，从而避免死锁。该算法在应用中维护方便且表现出较好性能。

A concurrent control algorithm of distributed data management based on the lock is presented in this paper. This algorithm can process the conflicts without communication among all the schedulers on every distribution site, but only needs information exchanges going on among the conflict initial sites and all the source sites. Again, in the case of conflict occurence, a transaction order is established by using a time stamp so as to avoid the dead lock. Accordingly, this algorithm shows the better performance in convenient maintenance in its application.
