通常用系统顺序图来画一个用例场景(例如主场景或复杂的常用的场景)。 1、首先要画一个system,前面要加个冒号,不写system,扣全部分,不写冒号扣1分,位置放错扣1分。 因为要画的是系统事件,没有系统还画什么 2、顺序:最左边是actor(前面也要加冒号),然后是system,然后就是用例的外部实体 3、通常只要求描述一...
On the View tab, make sure the check box next to Connection Points is selected. This option makes connection points appear when you start connecting shapes.Now, drag shapes you want to include in your diagram from the Shapes window to the page. To rename text labels, double-click th...

A sequence diagram is one of the multiple types of system interaction diagrams used within Unified Modeling Language (UML) to visually represent interactions between the objects that live within a system. Specifically, sequence diagrams provide a view of the order in which those interactions occur th...
If the condition operand does not have an explicit guard, an implicit guard is assumed. So this fragment is always an either-or decision. Option: This combined fragment is modeled in the sequence diagram like the alternative. It also stands for a decision. However, there is only one operand...
can be depicted so beautifully with sequence diagram, nothing comes closer to that 12 00:01:02,338 --> 00:01:07,539 Now the problem with sequence diagram is that you need to draw a diagram, you need to use 13 00:01:07,539 --> 00:01:13,099 ...
A new sequence diagram calledSequenceDiagram1is created in the View Browser, and theSequence Diagramtab becomes active. UnderSequence Diagram Properties, you can rename the sequence diagram. Alternatively, you can use theaddInteractionfunction to create a new sequence diagram. ...
Task Sequence Variable: Add a task sequence variable, condition, and value to evaluate. The conditions are the same as for step conditions. The rule evaluates to true when the value set for the variable meets the specified condition. Specify one or more variables to set for a rule that eval...

2. Solve the first common difference of a. Consider the solution as a tree diagram. There are two conditions for this step. This process applies only to sequences whose nature is either linear or quadratic. Condition 1: If the first common difference is a constant, use the linear equation...
