前一篇博客对报名管理系统进行了系统分析，以下是对该系统的设计。

系统设计分为五个部分：

1.  系统体系结构  
    ![46a897d5-0483-3b98-9c10-28df943b9124.png][]

横向：1、考生向服务器提出请求；

2、服务器将请求转发给控制器；

3、控制器根据请求的不同调用模型，进行必要的数据操作；

4、控制器把处理结果转发给显示视图；

5、视图对信息处理结果进行格式化并返回结果给服务器

6、服务器把信息处理结果回送给客户机并呈现于考生。

纵向：

系统软件层：

由操作系统或应用服务器提供的某些功能包，如：对磁盘的操作、应用服务器提供的负载均衡；

中间件层：

有某些开发环境或专门的应用工具提供的功能包，如：考生填报系统所需的Java的java.sql包，成绩统计分析所需的报表工具提供的相关功能；

通用应用层：

能在当前项目内实现重用的功能包，如：数据库功能包（考生信息存储），打印功能包（准考证打印）等；

专用应用层：

该系统所需的专门应用功能包，通常有开发者自己开发该功能包用于考生专业的业务功能，如：报考系统的考生信息管理功能，学籍、推荐信审核功能等。

1.  “考生报名”用例设计
    
    用例设计流：
    
    用例名：考生报名
    
    基本操作流程：

1.  考生登录进入到个人信息填写页面，在基本信息填写完后考生点击“确认并提交”按钮，系统审核该考生是否具有学信网学籍；
2.  之后进入到报考信息填写界面，考生填写报考信息，在考生选择了报考学院（下拉框列表）后，系统在专业一项的下拉框列表中提供可选的专业，选择完专业后，系统在导师一项的下拉框列表里提供可选的导师，在填写完成后考生点击“确认并提交”按钮；
3.  考生进行专家推荐信上传，通过文件浏览的方式进行推荐信的上传，考生点击“确认并上传”按钮，系统审核推荐信是否通过（两封且推荐信符合规范）；
4.  系统整理并通过视图将考生所填写的资料呈现给考生，并让考生通过点击按钮“确认”和“修改”对所填信息进行确认或修改；
5.  考生进行考试报名费的缴支付，系统显示报名费的金额，考生单击系统超链接“在线支付报名费”；
6.  系统审核考生的个人信息、报考信息、专家推荐信以及报名费；
7.  信息审核通过，系统报存考生报考信息，并显示准考证原件页面；
8.  系统自动生成考生准考证号，准考证号规则：年份（4位）\+学院编号（4位）\+专业编号（3位）\+序号（两位）；
9.  系统生成考生准考证，考生可通过点击“打印准考证”超链接进行准考证的打印。

1.  用例“考生报名”交互图设计
