摘要
实时数据库系统是事务和数据都具有显示的时间限制的数据库系统,与传统的数据库系统相比,其调度和并发控制策略、方法、机制有所不同。该文在分析实时数据库系统事务并发执行的新特点的基础上,介绍了几种具有代表意义的并发控制协议,总结了三种用于分析比较并发控制性能的方法,并分析了上述并发控制协议的性能。
Real -time Database systems which its transactions and data have timing constraints have different concurrency control strategies,methods and mechanism from traditional database systems.This paper introduces some representative concurrency control protocols after analyzing the new characteristics of concurrent executing of real-time transactions,and presents three typical methods for comparing system`performance.Lastly,the performance for these concurrency control protocol is analyzed.
