图文办公信息系统中的数据库设计

The Database Design of Geographical Information System

随着Internet/Intranet的快速发展,数据库技术的进一步成熟,使得GIS空间数据管理与应用呈现多用户、分布式和网络化的特点。建立能业务化工作的图文办公信息系统(GOIS)是当前国土规划管理部门的迫切要求,也是GIS应用研究的一个热点。该文以开封市土地利用规划管理信息系统(KF-LPIS)的建设为例,探讨了在三级客户机/服务器体系下,异质数据库服务器(文本服务器、Mapinfo空间数据服务器、Microstation空间数据服务器、大型全关系ORACLE8.1.6等)的协同运作问题,以及大型全关系数据库在图文办公信息系统中的应用前景。

With the development of Internet/Intranet and the maturity of database,the spatial data management and application of GIS is tending to multi-user and network distribution.It is exigent request to establish geographical office information system(GOIS),and is also a hotspot of GIS application research.The paper based on the Kai Feng land use planning manage information system(KF-LPIS),discusses the coordinatable operation of disparate and heterogeneous database servers(such as text database,Mapinfo spatial database,Microstation spatial database and large-scale re la tion ORACLE8.1.6)by the support of three-tiered client/server.The paper also puts forward the applicable perspective of large-scale relation database in GOIS.
