基于Geodatabase与CASE工具的林地保护利用规划数据库设计

Design of the Database of Forestland Protection and Utilization Planning Based on Geodatabase and CASE Tools

林地保护利用规划数据具有多源、海量的特点。针对Geodatabase手动建模费时的特点,利用Geodatabase与CASE工具(Visio)进行UML建型,建立林地保护利用规划数据库模型。该模型实现了林地保护利用规划空间与属性数据的一体化存储,缩短了开发周期。

The data of forestland protection and utilization planning is massive and multi-source.In view of time-consuming in manual modeling Geodatabase,in this paper,we used Geodatabase and the CASE tool（Visio） to carry on UML modeling,and established a specific databases model about forestland protection and utilization planning.This model realized integrated memory between the spatial data and the attribute data of forestland protection and utilization planning,and reduces the development cycle.
