【摘要】 海量空间数据的管理需要多服务器的支持,空间数据的跨服务器操作是必须解决的关键问题。针对Oracle数据库系统的Client/Server体系在管理跨服务器空间数据中存在的问题,利用远程内嵌过程和触发器等相关技术,设计并扩展了OracleSpatial的功能,实现了基于Oracle的空间数据跨服务器分布式管理。更多还原

【Abstract】 Management of vast quantities of spatial data requests the support of multi-servers,cross-server operation for spatial data is a key problem should be resolved.To the problems in management of Oracle Client/Server architecture mechanisms for cross-server spatial data,remote in-line procedures,triggers and other techniques are introduced.With the design of extended functions for Oracle Spatial,the distributed management for cross-server is realized.更多还原
