【摘要】 空间数据库引擎(SDE,Spatial Data Engine)作为中间件能较好地解决地理信息系统(GIS,Geographical Information System)中空间数据和属性数据统一存储和管理的问题。论文首先探讨了管线数据库的常用解决方案,再重点阐述了ArcSDE的数据库存储方法,最后通过实例详细论述了ArcSDE对管网空间及属性数据的一体化管理方法,对其他城市管网系统的建库工作提供了一定的参考价值。更多还原

【Abstract】 As the middleware,SDE stores and manages spatial and attribute data all together.Firstly,the frequently used solution of pipeline database was proposed,and then the storage of ArcSDE illustrated.Finally,the integrated management of underground pipe line spatial data and attribute data in RDBMS were analyzed by examples.This paper could be informative and instructive to the similar system’s database design for other cities.更多还原
