Geodatabase模型下城市公交线网数据库的构建研究

Research on Designing the Public-bus Network's Database Based on Geodatabse

Geodatabase是ESRI公司推出的新一代空间数据模型,其开创性地将面向对象的理念引入到空间数据库的数据组织和结构设计之中,极大地拓宽了此种数据模型的应用领域。本文通过介绍Geodatabase数据模型的结构特点和构建方法,并通过对城市公交线网数据库进行设计,充分证明了利用Geodatabase数据模型设计空间数据库所具有的实用性。

By Geodatabase which is a new generation of ESRI spatial data model,object-oriented concept is pioneeringly integrated into the data organization and the structure design of the spatial database.It expands the application field of such data model greatly.This paper introduces the structure of the Geodatabase data model and its designing method.At last it uses Geodatabase data model to design the database of the network of city public transportation and proves the practicality of applying Geodatabse data model to the design of the space database.
