多用户空间数据库的安全访问控制

地理信息系统现在得到越来越广泛的应用，特别是WebGIS的发展。空间信息通过网络的方式由众多用户共享。因此，多用户访问空间数据库的安全问题必须得到考虑。在由ArcGIS8.1,ArcSDE8.1,SQL Server建立起来的GIS系统的基础上,用基于视图的访问控制模型创建了ArcSDE和SQL Server之间的安全接口。

Security Access Control Based on Multi-user Spatial Database

The environments in which Geographic Information Systems are being implemented and used are changing rapidly ,specially the development of WebGIS,thus producing a rapidly growing need for consideration of the security of the information in these systems.Spatial information is being put online where it is more readily accessible to a much larger group of people.We will set up an enterprise level GIS environment using ArcGIS~(TM) 8.1,ArcSDE~(TM) and Microsoft SQL Server,and will (develop) a security interface between ArcSDE~(TM) and SQL Server using view-based access control.
