毕业设计（论文）摘要 Internet是当今世界上最大的计算机信息网络,它由一 些使用公用语言互相通信的计算机连接而成. 从网络通信技术的观点来看,Internet是一个以TCPIP (传输控制协议网际协议,协议是通信双方在通信 时共同遵守的约定)通信协议为基础,连接各个国 家,各个部门,各个机构计算机网络的数据通讯网 从信息资源的观点来看,Internet是一个集各个领域, 各个学科的各种信息资源为一体的,供网上用户共 享的数据资源网. 本论文主要包括学生选课系统方案分析与网络规划，本系统是一个典型的信息管理系统,其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备,易使用等特点。 利用其提供的各种面向对象的开发工具,首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。 本系统可以方便老师、学生更方便的选课。实现全校学生选课在线查询。还可以对新来的学生信息进行信息录入。由于学生上课情况复杂，可以实现信息修改，及时调整学生的基本情况。 关键字 Internet，管理系统，信息查询修改
