摘要
实时数据库系统不仅要求数据库的一致性,而且还要满足时间约束。在实时数据库系统中,紧迫性和时限是进行实时事务处理的两个重要特征。本文介绍基于这两个特征的并发控制策略。
The real-time database system not only requires the consistency of database, but satisfies the time constraint. The criticality and deadline are two important characteristics of transaction processing in real-time database system. This paper introduces the concurrent control policy based on these two characteristics.
