| 摘 要： | 实时数据库系统的事务调度一般只考虑事务的截止期,但是,在很多情况下,它还与数据截止期直接相关。对不同类型调度策略能否充分考虑数据截止期进行了具体分析,对其中存在的规律进行了归纳总结,并且在全面估算事务运行时间的基础上,给出了基于数据截止期和事务截止期的事务处理策略。

| Abstract: | Generally the deadline of transaction is only considered in dealing with real-time transaction scheduling, but in many cases, scheduling method is directly related with data deadline. This paper analyzed in detail if different scheduling strategy could consider data deadline and thus induced the existed nile. Based on the overall run-time estimation of transaction, the author offered the transaction strategy aimed at data deadline and transaction deadline. |

| Keywords: | data deadline priority assignment run-time estimation |
