综合应用算法训练
一任务说明
设计一个用于软件工程系本科导师制双选的系统。
设计要求：
(1) 实现学生信息管理，支持信息更新；
(2) 实现教师信息管理，支持信息更新；
(3) 实现学生填写导师志愿的过程，并提供当前导师的选择情况；
(4) 实现基于规则的志愿调整过程；
(5) 实现导师的学生筛选过程；
(6) 实现各种信息的多类查询。
二实验环境及实验准备
C#编程语言
三系统分析与设计
此部分包括软件程序的需求分析与软件设计部分，最好图文并茂。
（1）需求分析
参照实验要求，实现调用数据库进行信息显示，导师学生互选，更新互选结果，管理员更改教师、学生信息，查询双选结果，调整志愿。
（2）软件设计
数据库：教师表、学生表、管理员表
登录：点选教师/学生/管理员登录，输入正确用户名（教师号、学号）和密码成功登录。
教师：
默认可带5个学生。
邀请学生：列表显示未分配的学生信息，可选。若学生未达上限，即向选中的学生发出邀请，等待学生处理。学生将收到老师的基本信息和教学经历等内容。
处理学生申请：若收到来自学生的申请，可选择同意或拒绝。
刷新：更新显示信息
学生：
只能有一位导师。
修改个人简介：点击在文本框中输入要更改的内容，保存修改个人简介。
申请导师：若无导师，可在选择申请导师，向导师发送申请，等待老师处理。导师将收到学生的基本信息和个人简介。
处理导师邀请：若收到邀请，进入处理界面查看邀请信息，同意或拒绝邀请。
刷新：刷新显示信息
管理员：
进行教师表、学生表、双选表的增删改查。并将结果导出到.xls文件
说明本程序中用到的所有数据结构及数据类型的定义、主程序的流程以及各程序模块之间的调用关系图。
