实时数据库的核心问题是事务的处理既要确保数据的一致性,又要保证事务的正确性,
而它们都与定时相关联。本文对混合实时事务的真实时和非实时部分加以区别定义,建立了混合实时数据库模型,并分析了混合实时事务的调度与并发控制,可以更好地满足实时性时间约束需求,从而提高系统效率。

Abstract: The core problem of the real-time database system is to ensure the consistency of data and the correctness of events, which are related to time. In this paper, a transaction including genuine real-time and non-real-time is proposed, and hybrid real-time database system model is given. It discusses and analyzes the real-time transaction scheduling and concurrence control, which can meet the real-time requirement better, and improve the efficiency of system.
