| 摘 要： | 本文针对目前实时系统中优先级调度的不足，提出了一种新的定时调度的事务调度方法。该方法能以系统时钟的最小量度精确地实现事务的定时调度。它与传统的优先级调度方法结合使用，可以更好地满足事务的截止期。本文还讨论了实现该策略的一些问题。

| Abstract: | No priority based scheduling policy can apply to all the real time transactions, since it has a strong inclination for certain group of real time transactions. And since the priority queue determines a transaction can be scheduled only when it is its turn, we can't expect much accuracy in priority real time scheduling. This paper presents a new alarm scheduling scheme combined with the traditional priority based policy to provide a better performance in real time database systems. |
