UML通常分为两类:描述结构的UML图(Structural UML diagrams)和描述行为的UML图(Behavioral UML diagrams),具体见下表: UML | 类图 类图展示出OOP中的类,接口,及其中存在的关系,关联与协作。UML在类图中是标准化的。类是OOP的主要构件模块,而类图用恰当的结构展示OOP中遇到的一切,包括类,继承关系,类关系。它能够...
在谈论到CS的语言学习中,很多人都认为C, C++, Python, Java, Ruby, blabla...是computer science专业里最重要,最流行的语言,今天我要给大家澄清一下,什么才是计算机里最基本最通用的语言,UML: Unified modeling language. 这是一种以数据+图表的形式构成的统一建模语言,它不以目标语言为依据,比如说我们上述提到...
UML(Unified Modeling Language) 总结,模型:(1)概念:是对现实系统的简化或模拟,是对现实系统本质特征的一种简化、直观、类比和抽象的
“统一建模语言(Unified Modeling Language)是描述、构造和文档化系统产品的可视化语言。” 在上述中,UML的关键点在于可视化;UML是图形化表示法的事实标准,用来描绘和展示与软件相关的体系。 这里不会将UML的各种元素都提到,我只想讲讲类图中各个类之间的关系; 能看懂类图中各个类之间的线条、...
