# 实验六:交互建模 | ||
## 一、实验目标 | ||
1. 理解系统交互; | ||
2. 掌握UML顺序图的画法; | ||
3. 掌握对象交互的定义与建模方法。 | ||
|
||
## 二、实验步骤 | ||
1. 从用例图中找到参与者 | ||
2. 从类图中找到其他N个参与者(N+1) | ||
3. 从活动图中找到操作步骤 | ||
4. 按时间顺序(从上到下)画出参与者之间的消息 | ||
|
||
## 三、实验结果 | ||

图2:查询装备的顺序图 | ||
![修改装备信息的顺序图](./Sequence03.jpg) | ||
图2:修改装备信息的顺序图 | ||
|
||
## 四、课堂笔记 | ||
1. 顺序图:描述参与者与系统的交互/行为,包括参与者,生命线,事件、信号与消息,存活条。 | ||
2. 顺序图的“时间顺序”:仅表示前后顺序,不表示时间跨度。 | ||
3. 不同消息类型对应的不同箭头,常见的有同步消息、异步消息和返回消息。 | ||
