教务管理是大学的主要日常管理工作之一，涉及到师生方面的诸多信息，随着教学体制的不断改革，教务管理日常的工作日趋繁重，复杂，如何把教务工作信息化，模块化，便捷化是现代高效发展的重点，所以迫于需要研制开发一种综合教务管理软件，建成一个完整统一，技术先进，高效稳定，安全可靠的教学信息管理系统
这款教务系统比以往传统的人工管理更具有安全性和快捷性，更方便我们管理，对学校的整个教务系统变动进行综合管理和快速查询。为了节省在教务管理花费的人力和物力，同时便于学校掌握这方面的详细情况，有助于提高整个学校的教务水平和管理水平。
二、系统设计
（一）系统中的数据定义
管理员：增加数据
删除数据
修改数据
查询数据
学生：增加数据
删除数据
修改数据
查询数据
（二）系统的概要设计
管理员（学生）增加信息功能模块：管理员登入系统（进入图形化界面显示），输入待添加学生姓名，性别，学号，院系，籍贯，学分，电子邮件，联系方式等信息，是否继续添加，确认，保存信息
管理员（学生）删除信息功能模块：管理员登入系统（进入图形化界面显示），输入待删除学生姓名，学号信息，是否继续删除，确认，成功删除学生信息
管理员（学生）更新信息功能模块：管理员登入系统（进入图形化界面显示），输入待更新学生姓名，性别，学号，院系，籍贯，学分，电子邮件，联系方式等信息，是否继续更新，确认，保存信息
管理员（学生）查找信息功能模块：管理员登入系统（进入图形化界面显示），输入待查找学生姓名信息，是否继续查找，确认，显示学生信息
// jdbc

public static final String UPDATEVIEW_UPDATEBUTTON = "更新";
三、系统编码及运行（三号，宋体，粗体）
（一）系统开发涉及的软件
Eclipse
画图软件
Microsoft Word
（二）系统运行界面及结果
图1 主函数返回view界面
图2 图形化界面显示：
图3 原始数据库信息：
图4 查找信息：
图5 增加信息
图6 添加页面显示信息：
图7 删除信息现实页面：
图8 输入待删除学生的信息
图9 删除成功：
图10 信息的更新
图11 更新信息：
图12 更新后的结果显示
四、系统测试（三号，宋体，粗体）
教务管理系统是学校的管理核心，管理应设计到学校的专业设置，学籍管理，成绩管理，管理人员可以在互联网的任何地方办公，真正实现学校网上管理。开发“教务信息管理系统”的目的就是利用计算机的查询和运算功能，代替手工处理，提高了工作效力和质量，所以该系统是必要而且能够实现的。
在设计阶段，我们小组认为功能很容易可以实现，基本上都是对数据的增删改查，然而实际上在真正写代码的时候我们遇到了很多没有想到的问题，甚至一些问题会困扰我们程序的进行，我们组所以在各种论坛上寻求答案，花费长时间去参考其他项目的精髓，所以当我们成功运行程序，并且程序的功能越来越丰富时，我们都感受到了成就感，而且也增进了我们寝室共同学习的机会，也更让我们对Java、对数据库有了更深的了解和运用，知识真的不仅仅是停留在书本上，只有实际应用起来，才可以更好的运用，融会贯通，我们也感谢JAVA老师给了我们小组这一次通力学习的机会，让我们有机会赋予实践，以后的学习道路上，我们也会尽力合作，发挥特长，共同完成更好更优秀的项目

目录
（注：这部分可以点击右键更新生成，重新设置字体为四号）
教务管理是大学的主要日常管理工作之一，涉及到师生方面的诸多信息，随着教学体制的不断改革，教务管理日常的工作日趋繁重，复杂，如何把教务工作信息化，模块化，便捷化是现代高效发展的重点，所以迫于需要研制开发一种综合教务管理软件，建成一个完整统一，技术先进，高效稳定，安全可靠的教学信息管理系统
这款教务系统比以往传统的人工管理更具有安全性和快捷性，更方便我们管理，对学校的整个教务系统变动进行综合管理和快速查询。为了节省在教务管理花费的人力和物力，同时便于学校掌握这方面的详细情况，有助于提高整个学校的教务水平和管理水平。
二、系统设计
（一）系统中的数据定义
管理员：增加数据
删除数据
修改数据
查询数据
学生：增加数据
删除数据
修改数据
查询数据
（二）系统的概要设计
管理员（学生）增加信息功能模块：管理员登入系统（进入图形化界面显示），输入待添加学生姓名，性别，学号，院系，籍贯，学分，电子邮件，联系方式等信息，是否继续添加，确认，保存信息
管理员（学生）删除信息功能模块：管理员登入系统（进入图形化界面显示），输入待删除学生姓名，学号信息，是否继续删除，确认，成功删除学生信息
管理员（学生）更新信息功能模块：管理员登入系统（进入图形化界面显示），输入待更新学生姓名，性别，学号，院系，籍贯，学分，电子邮件，联系方式等信息，是否继续更新，确认，保存信息
管理员（学生）查找信息功能模块：管理员登入系统（进入图形化界面显示），输入待查找学生姓名信息，是否继续查找，确认，显示学生信息
// jdbc
public static final String JDBC_URL = "jdbc:mysql://127.0.0.1:3306/student?useUnicode=true&characterEncodeing=UTF-8";

public static final String PARAM_FIND_CONDITION = "";

public static final String PARAM_DELETE = "删除";
public static final String PARAM_UPDATE = "更新";

public static final String DELETEVIEW_DELETEBUTTON = "删除";

public static final String UPDATEVIEW_TITLE = "更新学生信息";
public static final String UPDATEVIEW_UPDATEBUTTON = "更新";
三、系统编码及运行（三号，宋体，粗体）
（一）系统开发涉及的软件
Eclipse
画图软件
Microsoft Word
（二）系统运行界面及结果
图1 主函数返回view界面
图2 图形化界面显示：
图3 原始数据库信息：
图4 查找信息：
图5 增加信息
图6 添加页面显示信息：
图7 删除信息现实页面：
图8 输入待删除学生的信息
图9 删除成功：
图10 信息的更新
图11 更新信息：
图12 更新后的结果显示
四、系统测试（三号，宋体，粗体）
教务管理系统是学校的管理核心，管理应设计到学校的专业设置，学籍管理，成绩管理，管理人员可以在互联网的任何地方办公，真正实现学校网上管理。开发“教务信息管理系统”的目的就是利用计算机的查询和运算功能，代替手工处理，提高了工作效力和质量，所以该系统是必要而且能够实现的。
在设计阶段，我们小组认为功能很容易可以实现，基本上都是对数据的增删改查，然而实际上在真正写代码的时候我们遇到了很多没有想到的问题，甚至一些问题会困扰我们程序的进行，我们组所以在各种论坛上寻求答案，花费长时间去参考其他项目的精髓，所以当我们成功运行程序，并且程序的功能越来越丰富时，我们都感受到了成就感，而且也增进了我们寝室共同学习的机会，也更让我们对Java、对数据库有了更深的了解和运用，知识真的不仅仅是停留在书本上，只有实际应用起来，才可以更好的运用，融会贯通，我们也感谢JAVA老师给了我们小组这一次通力学习的机会，让我们有机会赋予实践，以后的学习道路上，我们也会尽力合作，发挥特长，共同完成更好更优秀的项目
