组件重用技术在企业级GIS系统构建中的应用研究

摘要

This article looks back the progress of software reuse and analysis the feature of the reuse model based on component. We use ESRTS component GIS-MapObjects as aprogramming tool and give an example which shows how to create a component to label the realtimedata.%回顾了软件重用技术的发展过程，分析了基于组件的重用模型的特点.在此基础上以城市配电网GIS系统中实时数据显示组件的实现(借助ESRI公司的组件式GIS软件-MapObjects)为例，对企业级GIS系统构建过程中组件重用技术的运用进行了论述和尝试.
