摘要: |
空间数据库是 GIS 的核心。在介绍空间数据库的基本概念的基础上,着重分析了广为应用的空间数据库系统 SDE,它能将空间数据和属性数据集成在数据库中。目前已提出的空间信息模型可分为基于域的模型和基于对象的模型,各有其优点和局限。由于许多应用中需要这两种模型,因此本文提出了我们自行设计的一种能够集成域和对象的面向对象空间数据库模型。 |

Abstract: |
Spatial database is the core of GIS. First,we introduce the basic concepts of spatial database,and then analyze SDE,a spatial database which can integrate spatial data and attribute data. Currently proposed spatial information model can be divided into field-based model and object-based model. Each model has its advantages and limitations. Since both models are needed in application,we thus propose our object-oriented model,which integrates field-based and object-based model. |
Keywords: spatial database GIS object-oriented database SDE |
