Python设计模式 - UML - 活动图(Activity Diagram) 简介 活动图描述从一个活动到另一个活动的执行顺序、约束条件、引用对象及状态结果等方面的控制流,适用于对业务用例、工作流程或程序实现建模。 活动图建模步骤 - 确定活动图的范围和边界,对哪些工作流、哪些活动、哪些对象建模 - 确定工作流的开始状态和结束状态 ...
活动图是UML用于对系统的动态行为建模的另一种常用工具,它描述活动的顺序,展现从一个活动到另一个活动的控制流。活动图在本质上是一种流程图。活动图着重表现从一个活动到另一个活动的控制流,是内部处理驱动的流程。 一、活动图的组成元素Activity Diagram Element 1、活动状态图(Activity) 活动状态用于表达状态机...

3.2.3.1 Activity diagram Activity diagrams have a more prominent place in SysML than they do in UML. Many system engineers are familiar with extended functional flow block diagrams (EFFBDs) and activity diagrams are semantically similar if visually distinct. SysML activity diagrams are significantly...
Activity Diagram in UMLThe Activity diagram in the software design models is used to represent the flow of control among the different activities of the software. In the activity diagram, we represent different actions through activities. These activities take some input from some other activity of...
In UML 1, activity diagrams were seen as a special kind of state machine description and shared a great deal of terminology with UML statecharts. In UML 2, the semantics of activity diagrams became realigned to be closer to the semantics of Petri nets. An activity diagram consists of a ...
