黑河流域水资源调配管理系统空间数据库的设计与实现

为解决黑河流域水资源及其引发的相关问题，需要利用高新技术手段建立黑河流域水资源调配管理信息系统，而空间数据库设计与实现的研究是系统的关键性支撑内容之一．基于关系型数据库系统的空间数据库技术在海量空间数据的存储、管理、维护、查询方面具有许多文件方式的管理方法无法比拟的优点．文中介绍了黑河流域大型空间数据库的设计与实现过程，工作实践表明利用中间件技术，以大型美系型教据库系统为平台、采用面向对象的数据模型来管理海量空间数据是高效的。

Design and implementation of the space database for the configuration and management system of water resources in Heihe River Basin

To dealt with the problem of water resources in Heihe River Basin,the system of water resources configuration and management for the Heihe River Basin has to be built by means of new and high technology,and in particular the design and implementation of the space database shall be the centerpiece for the system.The space database technology based on RDBMS has incomparable advantages in store,management ,maintenance and inquiry of great capacity special data.The paper presents the design and implementation of the large space database.Practice has indicated that the orient object data model is the most effective,based on middleware technology with a large RDBMS as the platform.
