基于Oracle Spatial的矢量空间数据管理机制

Spatial Vector Data Management Mechanism based on Oracle Spatial

分析了基于Oracle Spatial的对象关系模型来存储和管理矢量空间数据的机制,包括其采用的数据模型、元数据管理机制、空间索引机制及查询机制,并在此基础之上给出了一个典型的基于Oracle Spatial创建和操作GIS空间数据库的实例.

This paper analyzes mechanisms including data model, management of metadata, spatial index and spatial query to store and manage vector spatial data based on Oracle Spatial object relation model and accordingly presents a typical instance to create and operate GIS spatial database based on Oracle Spatial.
