【摘要】 移动客户端缓存管理是移动数据库的关键技术之一,分布式数据库缓存管理技术不适用于移动数据库。和传统的分布式数据库技术相比,移动代理有很多优点。基于移动代理技术,建立了一个移动容广机缓存管理(CCM)模型并将其实现(CCM_BM)。在模拟的移动计算环境下,通过实验,测试了该原型在支持断接操作和响应时间方面的性能。更多还原

【Abstract】 Mobile client cache management is one of essential technologies in mobile database. Cache management technologies of dis-tributed database don’t work in mobile database. Compared with solutions of traditional distributed database, mobile agent has many ad-vantages. Based on mobile agent, a mobile client cache management model is established and realized. By experimentations, performancein response time and hit ratio is tested in simulating mobile computing environment.更多还原
