摘要
采用统一建模语言(unified modeling language,UML),对公路涵洞CAD系统进行了需求分析.模型中引入了查询道路工程数据库、涵洞标准图库等数据模块,使涵洞CAD系统在与外部系统数据传输上有了新的突破,系统不再成为封闭的孤岛.采用UML设计分析方法,可大大提高软件的复用性、可移植性、可扩展性和可维护性.
Need analysis of highway culvert CAD system based on unified modeling language （UML） has been finished. A breakthrough has been made in data transmission between culvert CAD system and exterior by using searching engineering database of the route,database of culvert standard diagram and so on,which make the system no longer a “dosing island”. The design and analysis method of UML earl enhance greatly reuse,transplanting,expansion and defenee of software.
