在分析分布式数据库系统的构成和特点的基础上,提出面向对象空间数据的表达方法,讨论了面向对象分布式空间数据库的构成,提出实现分布式空间数据共享的方法,设计了基于Oracle Spatial环境的分布式空间数据集成模式,为城市和国土资源空间数据的分布式管理与共享提供了具体思路.
On the basis of the analysis to the composing and characteristic of the distributed database, the thesis advances the object-oriented expression method of spatial data , discusses the composing of the object-oriented distributed spatial database in detail , puts forward to the method of the realization of the shared method of the distributed spatial data, designs the integration mode of the distributed spatial data based on the Oracle Spatial circumstance, offers the concrete thought of the distributed management and sharing of the spatial data in the city and land resource.
