摘要
缓存技术是提高数据访问性能的经典技术,已经在计算技术的很多方面得到了成功的应用。在移动计算环境中,由于设备和网络资源的限制,使得缓存技术的应用在移动数据库中显得非常重要。缓存技术的引入能有效减少带宽需求,降低通信成本以及节省移动计算机的能耗。然而,如何有效进行缓存维护从而确保一致性,一直是国内外研究的热点和难点。本文正是针对这一问题,对缓存一致性维护的各种研究方法的现状进行了深入剖析和探讨。
Caching is a classical technology for improving the performance of database access. It has been successfully applied in many aspects of computing technology. In mobile computing environment, because of the limitations of equipment and network resource, caching plays a more important role. For it can factually lower the.requirements of bandwidth, reduce the cost of communication and save energy for mobile computers. Nevertheless, how to effectively maintain cache and ensure the consistency of cache, is being the focus yet difficulty for research. Focus on this problem, this paper will offer a study on various kinds of cache consistency maintenance techniques.
