摘要
针对空间数据的特点设计了由缓存池与缓存文件组成的客户端缓存区域，详细介绍了缓存池结构、缓存文件组成以及在空间数据缓存过程中发挥的作用。通过实验证明：采用本文设计的缓存策略可以有效减少客户端访问服务器的次数，显著提高空间数据库的查询效率。
The paper designs a client data cache architecture consisting of cache pool and cache files according to the char- acteristic of spatial data. It makes a detailed introduction of the structure of cache pool, the organization of cache files, and the roles that they play in the data cache process. The experiment proves that the strategy proposed in this paper could effectively re- duce the access to server and greatly improves the efficiency of spatial database querying.
