| 摘 要： | 传统的基于锁的并发控制机制重点考虑数据的一致性和事务的并发度,不能很好地满足实时数据库系统对时态一致性的要求.结合锁、多版本和有效性确认等并发控制机制,提出了一种并发控制的新方法——自适应多版本实时事务并发控制方法:AMVCC.该法可根据具体情况自适应地采用不同的并发控制机制,有效提高了事务的并发度和截止时间内完成事务的数量.通过可行性分析性能优于传统并发控制方法.

| Abstract: | The traditional lock-based concurrency control mechanism emphasize the data consistency and the concurrency performance,it does not primely maintain the demand for the temporal consistency of the real-time database system.This paper presents a new concurrency control method for real-time transactions-adaptive multi-version concurrency control method(AMVCC)which based on the locking,multiversion and validity confirmation.This method can adopt the different concurrency control mechanism according to the idiog... |
