| 摘 要： | 随着空间数据获取能力的飞速发展,分布式存储管理的空间数据库将成为网络GIS的主要数据源。异构数据库、不同系统间的数据交互问题亟待解决。笔者在分析总结了异源GIS系统集成现状的基础上,引入中间件思想,构建了中间库集成模式,并应用在实际的地理信息系统集成中。

| Abstract: | Since distributed spatial database will be the main data source of Internet GIS,we have to cope with the intercommunication between heterogeneous databases and systems.At first,the paper analyses problems to solve the inter-access of heterogeneous database with the traditional strategy.A strategy of middleware is provided in this paper according to the problems.Later,we design a mode of middle database for spatial data intercommunication between heterogeneous databases.How to solve similar problems with the strategy of middle database mode in the real work is explained in this paper,too. |
