【摘要】 数据库系统采用的并发控制协议对数据库系统的性能影响很大。针对各种并发控制协议,设计人员迫切需要一个能够模拟真实运行环境的测试标准和测试系统。本文提出了一种基于多级多线程技术的数据库并发控制性能评测模型,它利用了多级多线程技术来模拟实际系统的运行,实现对数据库事务处理过程的性能测试,为数据库系统的设计提供了依据。在此模型下,实现了对基于ado.net的并发控制协议的性能测试,并分析了实验结果,结果表明该模型适合并发控制测评。更多还原

【Abstract】 The concurrency control protocol affects database system performance. Specifically for various the control protocols, designers need urgently testing standards and testing systems to simulate real running environment. We present concurrency control test system based on multi-level multi-thread technology that realizes the performance test on concurrency control protocol based on ado.net. We analyze the results. The experiment results show that the model fits for performance testing on concurrency control protocols.更多还原
