移动云数据库的协作式语义缓存设计

摘要

移动设备的数据访问量在不断增加,而且数据也越来越复杂,但是由于移动设备本身的约束,增加了用户的访问时间.为了解决这个问题,一方面引入了各个用户之间的协作式缓存,另一方面使用云资源.在这里,提供一个移动云数据库架构模型和协作式语义缓存算法,使用户可以根据自己对访问时间的需求,来决定采取什么样的方式来访问数据.%Growing demand for mobile access to data is only outpaced by the growth of large and complex data,accentuating the constrained nature of mobile devices.On the one hand,we introduce the cooperative semantic cache among different users,on the other hand,we use cloud resources to solve this problem.We present a mobile cloud database architecture model and a cooperative semantic cache algorithm by which the users can decide the manner to use to access data according to their demand of accessing time.
