【摘要】 自UML推出以后,很快就成为面向对象设计开发领域的常用工具,并成为一种工业标准而得到广泛的应用。本文根据农用地分等的基本原理和方法,采用ComGIS为系统开发平台,利用UML技术,从需求捕获、系统分析、系统设计与实现等方面对系统进行了分析与建模。研究表明,在农用地分等信息系统开发过程中,利用UML对系统进行建模分析能够取得较好的效果。更多还原

【Abstract】 Since it came into being, UML (Unified Modeling Language) has become a common tool for Object - Oriented Analysis and Development (OOA&D) and a kind of industrial criterion. Today it is widely used in many fields. Based on the basic principles and methods of farmland gradation, taking the composite geographic information system as the platform of system development and using UML techniques, this paper analyzes and models the Farmland Gradation Information System from aspects of demand capture, system analysis, system design and realization. It is proved that UML is very effective for the analysis and modeling of the Farmland Gradation Information System.更多还原
