摘　　要：提出了适用于移动实时数据库环境下基于优先级的多版本两阶段锁并发控制协议,它结合多版本并发控制机制和两阶段锁机制的优点,引入优先级概念对事务进行优先级别的划分,分情况进行考虑.通过仿真实验模拟,对该协议进行了性能测试,并与其他协议进行了比较,实验结果表明:该协议的性能表现良好.This paper proposes a multi-version two-phase locking concurrency control protocol based on priority , which can be applied to the mobile real-time database .This protocol combines with the advantages of multi-version concurrency control mechanism and two-phase locking mechanism , introduces the concept of priority to classify the transactions and consider them with different situation .We perform simulation experiments to test the performance of this protocol and compare it with other related protocols .The results of experiments indicate that the protocol performs well as expected .
