摘要
以实时数据库事务调度为典型应用背景,研究和分析了不精确性计算方法,给出了一个基于不精确性计算的事务模型,并基于该事务模型提出了一种基于反馈控制的实时事务调度体系结构以及建模方法,为最终提高在超载环境下实时数据库系统的服务质量提供了有效的解决方案。
With the scheduling of real-time database transaction as typical application background, we study and analyze on imprecise computing thesis and present the real-time transaction model based on imprecise computing. Based on this transaction model structure of scheduling of real-time database and method of modeling scheduling structure of real-time transaction based on feedback control thesis was presented, which improve the QoS of real-time database system in the overload environment.
