类图描述系统静态结构。 在系统的逻辑视图中,类图用于表示类和它们之间的关系。我们利用类图来说明实体共同的角色和责任,这些实体提供了系统的行为。 类图中的两个基本元素是类和它们的基本关系。 一、类表示法 类图标由三个部分组成:第一个部分是类名,第二个部分是属性,第三个部分是操作。 类名在它的命名空间中...

UML - Class Diagram - Class diagram is a static diagram. It represents the static view of an application. Class diagram is not only used for visualizing, describing, and documenting different aspects of a system but also for constructing executable code
Clearly identify what each class is responsible for. Don't include unnecessary properties in the diagram that might make it too complicated. Class notation Symbol Meaning - The attribute or operation is private. + The attribute or operation is public. ...
