项目运行截图

（按功能进行截图）

• 登录界面：首先展现的是登陆界面，需输入正确的账号密码才可进入系统。
  
• 注册界面：没有账号的可以通过注册获取，注册成功后再登入即可。
  
• 信息管理系统界面：展现已经存在在数据库中的信息，并展现六个功能。
  
• 添加功能（add）:添加学生信息功能，既能提交到表单也能存入数据库中。（体现学号唯一性）
  
• 删除功能（delete）：删除学生信息功能。
  
• 展现功能（show）：展现学生信息功能。
  
• 搜索功能（search）:搜索学生信息功能。
  
• 编辑功能（edit）：将表单上的一行信息对应填入相应文本框中，方便修改及添加。
  
• 修改功能（modify）:选中信息进行修改。

尚待改进或者新的想法

• 只是简单的做成图形界面形式，还可以继续改进为web。
• 从文件中添加数据功能尚未实现。
• 界面还不够美观。
