基于Oracle数据库的专题地理数据模型

Study of Thematic Geographic Data Model Based on Oracle Database

对OracleSpatial组件中空间数据存储结构及对象关系数据模型进行了分析,然后结合专题地理数据库课题,提出了一种运用Oracle数据库的组件OracleSpatial来管理专题地理数据的数据模型。并对这种数据模型的完整性和正确性进行了分析验证,取得了良好的效果。

First, storage structure of spatial data and the objectrelation data model structure about Oracle Spatial are analyzed. Secondly, we study the special geography database, and put forward the data model which manage the special geography data in Oracle Spatial. The result of analysis shows that the data model has the better effect.
