基于OCI的GIS数据库的开发与应用

Development and Application of OCI-based GIS Database

Oracle Spatial在空间数据库的应用,极大地方便了空间数据库的管理与维护。GIS作为空间数据库的典型应用,提高了数据库系统的有效可查性,并有着良好的应用前景。通过实例分析了GIS数据库的性能,并介绍了OCI接口程序在使用时的调用机理,同时阐述了GIS数据库以后的发展趋势。

The application of oracle spatial in spatial database is convenient for database management and maintenance.As a typical application of spatial database,GIS improves effectiveness of database system and has a favorable prospect in application.The performance of GIS database is analyzed by apractical example,the mechanism of OCI interface program for GIS database and the development tendency of GIS database are proposed.
