| 摘 要： | 常用的关系数据库缺乏直接管理空间数据的成熟的通用方案。借助于空间数据库引擎(SDE)技术,扩展了关系数据库功能,使关系数据库成为业务数据和空间数据的统一存储管理平台,并在此基础上建立了基于Geodatabase模型的灾害应急管理系统数据库,对系统数据整体结构进行研究设计,解决了空间数据和业务数据的关联问题,实现了灾害应急管理系统空间数据和业务数据的无缝集成和一体化存储。该方法已在省级应急管理信息示范平台上成功应用。

| Abstract: | At present,there is little mature solution to manage the spatial data in common relational database.In this paper,the technique of spatial database engine was used to extend the relational database and make it to be the unified storage and management platform for the business data and the spatial data.An emergency management system database model based on geodatabase was established and the structure of the system database was designed in this paper.As a result,the association of the spatial-data and the bu... |
