【摘要】 利用优先级分配原则构建了嵌套实时事务模型,提出了一种充分利用动态乐观并发控制协议与基于优先级继承的嵌套锁协议优点的混合并发控制策略.该模型减少了事务等待的时间,提高了满足截止期要求的事务的数目,从而提高了系统的性能.更多还原

【Abstract】 Based on the principel of priority inheritance,a nested real-time transaction mode was constructed,and a concurrency control,which fully inherits both the merits of the dynamic optimism concurrent control protocol and the merits lock protocol based on priority inheritance principle,was proposed.The model could reduce the waiting time of transactions and increase the number of the transactions satisfying the requirement of deadline.Therefore,the model could improve the efficiency of the system.更多还原
