摘　　要：自主设计了海量栅格空间数据库的逻辑模型和物理模型,实现将海量栅格数据存储于大型商业关系型数据库中;提出了基于CORBA(Commoh Object Request Broker Architecture)技术的海量栅格空间数据库引擎四层体系结构,并在此基础上给出运行实例,取得了良好效果,证明了自主栅格空间数据库引擎的可行性.A logical and physical model for massive raster spatial database is independently designed. The storage in the relational database for massive raster data is implemented. And the Four-tier architecture for massive raster spatial database engine is put forward, which is based on Common Object Request Broker Architecture. Finally, an application case of massive raster spatial database engine is given, which proved the feasibility of the self-designed raster spatial database engine.

关 键 词：海量栅格空间数据库引擎 四层体系结构 CORBA关系型空间数据库
