UML在河北气象站网管理信息系统中的应用

Application of UML in Hebei Management Information System of Meteorological Station Network

本文介绍了一种可视化的建模工具——统一建模语言(UML),阐述了它的显著特点以及可视化的建模方法,并以气象站网信息系统为例,分析了该系统功能需求,运用统一建模语言建立了该系统的静态模型(用例图、包图)和动态模型(活动图、顺序图),这些模型将有利于开发人员有效地对目标系统进行需求分析、系统设计、源程序自动生成,以及通过逆向工程返回到分析设计阶段,使系统能适应需求变化的要求,从而缩短软件开发周期,提高软件系统的质量。

A type of visible modeling tool-Universal Modelling Language （UML） is introduced, together with its main features as well as the method of visible modeling. Taking the information systems of meteorological obeservation network for example, on the basis of analysing function requirement of this system, static model and dynamic model of the system are built with UML. Those models will help developers efficently carry out requirements analysis, system design, automatic generation of original codes, and make the system adapt to the change of requirement by returning to the stage of analyse and design through retrorse project. As result, the periods for software development will be shorten, and the quality of system will be improved.
