# 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。
