# 实验三:过程建模 | ||
|
||
## 一、实验目标 | ||
|
||
1. 掌握过程建模方法 | ||
2. 掌握活动图的画法(Activity Diagram) | ||
|
||
## 二、实验内容 | ||
|
||
- 根据实验二中的用例规约绘制活动图 | ||
|
||
## 三、实验步骤 | ||
|
||
1. 创建浏览图库、评论帖子的活动图 | ||
2. 添加Iniial(开始节点)和Final(终止节点) | ||
3. 根据用例规约添加Action(动作状态) | ||
4. 扩展流程处先使用Decision(分支),然后Merge(合并) | ||
5. 用Control Flow(控制流)连接 | ||
6. 调整位置直至不交叉且整洁 | ||
7. 导出并上传活动图 | ||
|
||
## 四、实验结果 | ||
