摘要
用现代数据库统一来存放和管理空间数据与属性数据是GIS的发展趋势。利用Oracle数据库的Spatial模块,可以进 行空间几何数据的相关存取,方便地实现对空间几何数据的管理。通过开发基于J2EE构架的Oracle数据库应用程序,实现 了矢量图形数据的存取,提出了一种开发GIS矢量图形系统的新思路。
It is the developing trend of GIS to store and manage the spatial data and attribute data with modern database. Using the spatial modules of Oracle database, we can access the spatially geometrical data and realize the management of spatially geometrical data conveniently. Through exploiting the applying program of Oracle database based on J2EE, the access of vector graphics data is realized and a new method of developing vector figure system on GIS is brought forward.
