摘要
为使Web应用系统能够有效、快速地访问数据,分析当前Web系统三层框架有关数据缓存和访问优化的技术,通过对JDBC接口原理及实现技术的深入研究,提出基于JDBC的数据自主识别、前置驻留与快速访问的策略和实现方案。使用key-value存储机制,通过客户端-应用层的快照数据快速访问机制提升Web系统综合性能。测试结果表明,该方案能够有效提高Web系统在数据访问的响应速度,实现多客户端的数据共享,具有一定的普适性和推广价值。
To access data effectively and quickly for Web system, the technologies of data caching and access optimization for the three-tier architecture of popular Web application system were analyzed. Through further researching the JDBC interface princi- ple and realization technology, the strategy in which data were independently recognized and the pre-process of data was quickly accessed was proposed. Key-value storage mechanism was adopted to improve the performance of Web system using rapid snapshot-data access mechanism in the client-application layer. Experimental results show that the scheme can effectively improve the Web speed of data access and it is able to achieve multi-client-side data sharing with a certain degree of universality and promotional value.
