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,缓存将发挥更加重要的作用。研究了移动数据库中的客户端缓存管理技术,重点讨论了缓存管理的缓存粒度、缓存一致性策略和缓存替换策略3个关键问题。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. Technology of client cache management in the mobile databases was researched. Three key issues of mobile cache management such as caching granularity, coherence strategy and replacement policy were discussed and analyzed particularly.
