实时数据库事务调度分析

Analysis of the Transaction Scheduling Tactics in RTDB

指出了调度策略选择的好坏决定了系统性能的优劣 ,根据实时数据库中事务的基本特性 ,具体分析了在实时数据库中影响事务调度策略选择的主要因素 ,包括截止期类型 (硬实时截止期和软实时截止期 )、调度方式 (静态调度和动态调度 )、调度准则、调度的性能测度和可预测性 .

Indicating that the performance of system dependents on the choice of the scheduling tactics. On the basis of the transaction's property in real time database, this paper analyses the main factors that influence the transaction scheduling tactics in real time database, include the type of deadline(hard real time deadline and soft real time deadline), the mode of scheduling(static scheduling and dynamic scheduling), scheduling criterion, performance measures and predictability.
