学生档案管理系统数据库设计书1.1 课程设计目的编写的这个再就业服务中心管理信息系统，第一是为了学以致用，将学到的知识运用到实际中去，第二也是为了学到更多的东西，加深自己对C#和SQL的理解。

1.2 开发背景随着我国市场经济的快速发展和信息化水平的不断提高和网络运用的不断普及，如何利用先进的管理手段，提高高校管理的水平，是当今社会所面临的一个课题。

各种各样的网上管理系统应运而生。

1.3 需求分析1.4 开发环境Visual Studio 是微软公司推出的开发环境。

是目前最流行的Windows 平台应用程序开发环境。

Visual Studio 可以用来创建Windows 平台下的Windows 应用程序和网络应用程序，也可以用来创建网络服务、智能设备应用程序和Office 插件。

2.1 系统功能描述学生档案管理系统包括用户管理模块、档案管理模块、成绩管理模块，奖惩管理模块、基本信息管理模块、帮助模块。

用户管理模块：对系统用户进行管理，包括添加新用户，对已有用户的查询修改，用户密码采用md5加密方法进行加密，以提高用户帐号的安全性。

档案管理模块：对学生的档案信息进行管理，包括档案的录入，档案的查询，档案的修改，方便管理者进行管理，无需传统的手填表式管理，降低了出错的可能性。

成绩管理模块：对学生的成绩进行管理，包括成绩的录入，成绩的修改，成绩的查询，方便管理人员适时的对学生的成绩进行操作，同时也方便了管理人员对学生成绩的了解。

奖惩管理模块：对学生的奖惩信息进行记录，修改，查询，让每个人的信息可以及时的体现在档案上，方便以后的查询。

基本信息管理模块：对学生的一些基本信息进行管理，及时的修改学生的基本信息，可做到及时性，准确性。

帮助模块：对学生档案管理系统进行介绍，对一些基本信息和使用方法向用户做初步的介绍，方便用户的使用和减少用户摸索的时间，提高用户的工作效率。
