一、题目内容
嵌入式Linux数据库编程，用C实现成绩管理系统，通过图形化界面查询。
二、设计框架
（一）登陆界面
输入账号，密码后，如果账号密码匹配则进入系统，否则弹出错误提示框，提醒登陆用户账户或密码错误，请重新输入。
（二）功能界面
用户可选择相应的功能进行操作。功能界面分为学生基本信息查询，学生信息添加，学生信息修改和按条件查询。
（三）学生基本信息查询
在学学号处输入学号，即可查看学生个人信息。括学生姓名，性别，各科成绩等。
（四）学生个人信息添加
在学生个人信息添加模块中，我们先在每个选项中输入相应的值，最后按确认即可完成添加。
（五）学生个人信息修改
我们通过此模块，我们可以对已存在的学生信息进行更改，只需在相应的选项中按要求输入，即可完成更改。
（六）按条件查询信息
我们按要求输入我们需要查询对象满足的条件，最后按开始，即可查看满足要求的信息。
三、设计详细过程
（一）登陆界面
1.实现功能
输入账号，密码后，如果账号密码匹配则进入系统，否则弹出错误提示框，提醒登陆用户账户或密码错误，请重新输入。
2.设计思路
main()函数主要是画出用户文本框的和密码输入文本框，和一个“登陆”按钮，当用户按下确认是，就会触发按钮时间，调用callback_buttton()函数对按钮事件进行响应。初始设置用户名为：cyp,密码为：123。

（一）功能界面
1.实现功能
用户可选择相应的功能进行操作。功能界面分为学生基本信息查询，学生信息添加，学生信息修改和按条件查询。
2.设计思路
calllback_button()函数主要是对输入界面的响应。获取用户输入的账号和密码，并进行判断，如果匹配则进入功能界面，否则弹出提示框，提示用户密码或账号错误。功能界面主要是四个按钮，按钮被绑定相应的函数。
3.成果展示
（三）学生基本信息查询
1.实现功能
输在学学号处输入学号，即可查看学生个人信息。括学生姓名，性别，各科成绩等。
2.设计思路
callback_button1()是对查看个人信息按钮事件的响应，画出成绩按输入学号查询的界面，包括个人所有信息。在这个界面中的“确定”按钮绑定函数lookfor()，并作出相应的处理。
lookfor（）函数主要是打开学生成绩管理数据库，并按照用户输入的学号，并根据学号信息生成相应的sql语句，通过数据库查询成绩，如果没有查找到相关信息，则输出提示框提示用户查询失败，否则就将查询到的信息显示到界面中。
3.成果展示
（四）学生个人信息添加
1.实现功能
输在学生个人信息添加模块中，我们先在每个选项中输入相应的值，最后按确认即可完成添加。
2.设计思路
callback_button2()是对查看个人信息添加按钮的事件响应，画出成绩插入的界面，包括个人所有信息。在这个界面中的“确定”按钮绑定函数lookfor1()，并作出相应的处理。
lookfor1（）函数主要获取用户的输入的个人信息，如果某些选项没有输入，则表示此项为默认值，根据用户的输入信息处理成的数据库插入语句，用sqlite3_exec()执行sql语句，根据插入情况，弹出插入失败或成功的提示框。
3.成果展示
（五）学生个人信息更改
1.实现功能
我们通过此模块，我们可以对已存在的学生信息进行更改，只需在相应的选项中按要求输入，即可完成更改。
2.设计思路
calllback_button3()函数主要是对输入界面的个人信息修改按钮响应。画出用户的个人信息输入界面，具体的修改过程由本界面中“确认”按钮绑定函数lookfor2()完成。
lookfor2()函数的先根据输入的学号，查找相应的信息。在将从界面用户输入将要修改的信息，如果某项输入为空，则有查找出原来的信息项代替，根据这些信息形成sql插入语句，先把此学号的个人信息删除，再将我们得到的sql语句用sqlite3_exec()完成插入，即可完成用户的信息修改。
3.成果展示
（六）按条件查询个人信息
1.实现功能
我们按要求输入我们需要查询对象满足的条件，最后按开始，即可查看满足要求的信息。
2.设计思路
calllback_button4()函数主要是对功能界面的按条件查询个人信息按钮响应。主要是画出界面，包括用户条件选择组成部分，选择显示选项部分，和显示部分组成。按下“开始匹配”按钮后，就开始打开数据库，按条件查询，并作出将查询的结果显示到界面上，显示界面是滚动类型界面。
lookfor4()函数主要是从界面获取用户需要显示的条件信息，并根据条件形成sql语句，从数据库中查询信息，并将获得信息显示到界面中。
3.成果展示
