摘要

传统的基于锁的并发控制机制注重数据的一致性和事务的并发性,不能满足实时数据库系统对时间一致性的要求。本文在对实时事务并发控制协议进行改进后,提出了一种基于锁定、多版本和有效确认并发控制机制的新的并发控制方法。该方法可以根据具体情况采用不同的并发控制机制。这样可以有效地提高事务的并发性,增加在截止日期内完成的事务数量。可行性分析表明,该方法在性能上优于传统方法。

Research on the Improvement of the Concurrency Control Protocol for Real-Time Transactions
The traditional lock-based concurrency control mechanism which focuses on the data’s consistency and the transactions’ concurrency cannot meet the demand that the real-time database systems make on the temporal consistency. After the improvement of the concurrency control protocol for real-time transactions, this paper will present a new concurrency control method which is based on the locking, multi-version and valid confirmation concurrency control mechanisms. This method can adopt different concurrency control mechanisms according to the idiographic situation. In this way it can effectively improve the concurrency of transactions and increase the amount of the transactions completed within the deadline. The feasible analysis denotes that this new method is better than the traditional one on performance???
