摘要: 针对数字流域模型系统中海量数据的存储和管理问题,采用ArcSDE空间数据引擎,将空间数据与属性数据有机地结合,由关系数据库进行统一管理,并遵循相应的规则将数据进行入库,通过关系类为数据建立关联关系,然后采用面向对象的方法设计相关类来管理各类型数据,以保证对象的一致性和便于维护及扩展。

关键词: ArcSDE, 空间数据引擎, 数据库, 面向对象, 关系类

Abstract: To cope with the storage and management of mass data in the digital basin model system, the authors proposed an approach of database construction based on ArcSDE spatial data engine. The spatial data dynamically integrated with the attribute data are managed by the relational database. Having been loaded in line with corresponding rules, the spatial data and attribute data were associated by relationship classes. And the object-oriented method was employed to manage various classes of data in order to ensure the object consistency and the database maintenance and expansion.

Key words: ArcSDE, spatial data engine(SDE), database, object-oriented, relationship classes
