摘　　要：针对目前分布式系统中存在的问题,详细分析了分布式系统和并发控制协议对实时事务调度策略的影响,鉴于目前真正的分布式实时事务调度策略尚处于探索发展阶段,现提出一种分布式最少剩余时间优先的调度策略,通过实践结果证明,该调度策略比传统调度策略更适用于分布式实时数据库环境中。Aimed at the current problems in distributed systems, the influence of the distributed systems and concurrency control protocol on the real-time transaction scheduling are elaborately analyzed. Since the distributed real-time transaction scheduling strategy is still at the exploratory stage, a least distributed time priority scheduling strategy is proposed, which is proved to be more suitable for the distributed real-time database environment than the traditional one.
