摘要
移动数据库的缓存技术使客户机通过缓存少量的服务器数据项,便能拥有较高的处理速度,而且,它也是解决移动数据库频繁断接性问题的关键技术。文章研究了缓存管理策略在移动数据库中的应用,重点研究了缓存管理策略三大关键问题:缓存粒度、缓存一致性以及缓存替换,提出了一种基于统计与优先级原则解决缓存一致性问题的新思路。
Cache technology in mobile databases enables clients to obtain high processing speed by caching a small number of server data items, and it is also the key technology for solving the problem of frequent disconnection in mobile databases. We research the application of cache management strategy in mobile databases, especially the three key issues of cache granularity, cache coherence and cache replacement in cache management strategy, and propose a new idea based on statistics and priority for solving cache coherence.
