【摘要】 在地理信息系统的发展进程中,随着处理的空间数据量的日益增大以及对数据质量要求的同益提高,从而使得通过一个良好的空间数据库系统在整个系统中显得尤其重要。合理的空间数据组织方式不仅能提高整个系统的性能与效率,而且还可以大大减少后期的维护工作,从而使得整个系统显得健壮。因此,分析研究空间数据库是目前GIS领域中的一个重要内容,是很有必要有意义的一项工作。本文首先空间空间数据库的概念入手,在介绍空间数据库系统若干基本概念和发展现状的基础上,着重分析了构建空间数据库系统一些关键性的技术,本文最后在ARCGIS提供的新一代数据模型Geodatabase的基础上,根据一个工程项目的任务需求,在服务器端选用关系数据库Oracle9i与空间数据库引擎ArcSDE8.1相结合的方式,对空间数据进行管理,并完成空间数据库的研究与设计。更多还原

【Abstract】 In the development progress of the geography information system, measures along with the processed space data of enlarge increasingly and the logarithms requests according to the quantity of increases increasingly, from but make pass a good space database system to seem to be particularly important in whole system. The reasonable space data organizes the way can not only increases the function of whole system and efficiency, but also can reduce the in the late maintenance work consumedly, from but make whole system seem to be the haleness. Therefore, the analysis research space database is current an important contents within GIS realm, having very much necessity meaningfully of a work. This paper the concept of the space database commences first, in introducing space database system some basic concepts with the foundation that develop the present condition, emphasized to analyze to set up the some key technique in system in database in space, this paper finally in the foundation of the new generation data model Geodatabase that ARCGIS provide, according to an engineering item of the mission requires with, carrying to choose to use to relate to the database 0racle9i in the server and space database- powered AicSDE8. 1 the way that combine together, proceed the management to the space data, and the research that complete the space database and design.更多还原
