摘要
在移动客户端建立缓存可以提高移动数据库系统的性能,也会带来服务器上的数据和缓存中的数据不一致的问题。针对这一问题,文中分析了已有解决方案的不足,建立了基于Agent的缓存系统模型。在此基础上提出一种缓存管理方案,充分考虑了移动环境的特点,对移动客户端进行分组管理,利用Agent技术解决了缓存失效问题。最后将该策略与传统经典策略进行分析比较,通过模拟实验表明该原型相对于传统缓存失效解决方案具有更好的性能。
Establishment of mobile client cache can improve the performance of mobile database system, but it also cause problem of data inconsistency. In order to resolve the problem, analyzed deficiency of scheme that had been used and proposed a cache management scheme based on agent technology, which resolved the problem of cache invalidation and reduced the consumption of network comunication. Finally, simulation experiment indicates that the prototype for improving the performance of the cache is effective.
