摘要
介绍Geodatabase数据模型、UML语言和CASE工具的特点,对森林资源二类调查数据库结构进行了分析和设计,然后应用Visio 2003创建了Geodatabase模型.认为与传统方式相比,该方式具有数据库结构调整方便,开发周期缩短的特点,并实现了空间数据与属性数据的一体化存储.
The paper introduces characteristics of Geodatabase data model, UML language and CASE tool, and analyzes data structure of second inventory of forest resources. Geodatabase model is established based on Visio 2003. Compared with traditional way, the method can easily change the structure, shorten the period of developing, and realize integrated memory between spatial data and attribute data of forest resources.
