the thesis proposes a mobile client caching scheme based on semantic caching, which explores the semantic locality among client issued queries 本文提出了一个基于语义缓存的移动客户缓存机制。
the driver may use several algorithms, including the lru least recently used replacement algorithm, to implement the caching scheme 驱动程序可以使用多种算法来实现缓存方案,包括lru(最近最少使用的)替换算法。
if the device supports both the system and video memory pools for textures, the application may implement its own memory caching scheme by using the 如果设备同时支持将系统和视频内存池用于纹理,则应用程序可以使用
in this way, associative database access is supported, and system performance and data availability during disconnection improve . based on this caching scheme, the thesis investigates thoroughly key issues on cache replacement strategy, cache coherency policy, and query processing algorithms 基于该缓存机制,本文就缓存替换策略、缓存一致性维护策略和基于缓存的查询处理这几个关键技术对移动客户缓存进行了深入的研究。
to support the mobile client cache, the thesis first presents a hybrid client-server database architecture . then the main idea behind the caching scheme is given, which is followed by the definition of cache admissible query . the content and organization of cache and the combination strategy of cache items are also discussed 本文首先给出能支持移动客户缓存的客户?服务器数据库混合结构;随后详细讨论了缓存机制的基本思想,可缓存查询,缓存的内容和组织,以及缓存项的合并策略;并给出缓存系统的结构组成以及各构件的功能。
