摘要
介绍SDE是怎样将空间数据存储在关系数据库中,并在此基础上介绍存储在关系数据库中的空间数据是如何与也在同一数据库中的非空间属性数据进行链接的。
Like other information systems, database plays a significant role in GIS. However, because of some features of the spatial data difficult to be represented with the relationship model, there are some problems in applying RDBMS directly to GIS. This paper mainly introduces the geometry storage schema used by SDE (Spatial Data Engine), and explains how to realize the integration of spatial data and attribute data in RDBMS.
