基于Oracle的“数字城市”基础地理空间数据库的实现

Realization of basic geography spatial database on cyber-city based on oracle

基础地理空间数据库是搭建“数据城市”的基础平台。随着空间观测技术的不断发展,基础地理空间数据正在呈几何级数增长,如何组织、调度、存储与管理海量的空间数据,满足国内数字化生产和国家基础地理信息产业建设的迫切需要,更好地促进“数字城市”的发展,是当前GIS界面临的重大问题。针对上述问题,本文提出了一种基于J2EE三层体系结构的基础地理空间数据库在Oracle数据库中的实现方法。

Basic Geography Spatial Database is fundamental platform for building cyber-city.Basic Geography Spatial data quantity is increasing by geometric series along with the development of spatial surveying technology.It is an important issue to organize,store and manager magnanimity basic Geography Spatial data,so as to satisfy with national digitalized product and development on national basic geography information industry and promote preferably development of cyber-city.The paper puts forward a method of realization on basic geography spatial database with Oracle based on J2EE Tri-tier System framework.
