摘要 系统地分析了大型实时数据库系统的应用环境和功能需求,提出了企业大型实时数据库的体系结构、设计思路和实现方法,研究了实时主动数据库事务执行模式,提出了有效性检查并发控制协议。协议使用动态调整串行次序策略,避免不必要的事务重启动,能有效降低事务延误截止时间,在工程应用中取得了良好的效果。 The function and the application environment of great Real-Time Database System (RTDS) are analyzed in large enterprises. According to the technology of real-time database, a design method of large real-Time database in petrochemical enterprises is presented. This paper studies the model of transaction execution and presents Real-time Validation Concurrency Control (RTVCC) protocol for RTDS. The protocol uses dynamic adjustment of serialization to avoid the unnecessary transactions restarts, and the protocol can effectively reduce missing rate.
