基于B/S结构的选课系统（代做计算机毕业设计）
摘要
随着高校招生规模的不断扩大，许多学校出现两个及两个以上校区并存的局面，并且校区之间的地理位置跨度较大，传统的选课模式已不能满足纷繁复杂的课程体系安排，应当借助于现代化信息技术来改善教育模式。在这个高速信息化的背景下，也是为了减轻辅导员和教务管理人员的工作量、曾强学生选课时的主动性和积极性，我研究和设计了一个基于B/S模式的网上选课系统。
借助于信息化的软件开发出的这个系统可以帮助学校教师更快捷、更方便的处理各院系学生选课过后的信息整合，提高工作效率和准确却行。此次的研究与设计的实现借助于Microsoft Visual Studio 2008系统开发平台，链接SQL 2008 数据库，运用c#语言作为其开发代码，根据登录使用者的身份不同给予不同的权限，设有学生，教师，管理员三种模式。给予其选择、添加、删除、修改、管理等功能。既节省了人工进行筛选安排的时间又提高了学校工作的效率，一举两得。
在本文中我重点介绍了本系统各个模块内容，包括学生，教师，管理员三者的系统设计，总体设计，功能实现。对于目前的研究现状，和未来发展，软件特性都做了比较具体的叙述。希望在看过此篇论文的老师和同学能给予一定的意见的建议。

Abstract
With the enlargement of college enrollment scale, many schools in the two and the situation of coexistence of two or more campus and campus location between the span is larger, the traditional pattern of course already cannot satisfy the complicated course system arrangement, should with the aid of modern information technology to improve the education mode. Under the background of the high speed information, but also to reduce the workload of counselors and educational administration personnel, when choosing courses has been strong students’ initiative and enthusiasm, I research and design a online course selection system based on B/S mode.
By means of information technology software development of the system can help the school teachers faster and more convenient to handle all the departments after the students' course selection information integration, improve the work efficiency and accurate. The research and design of the implementation of the development platform by using Microsoft Visual Studio 2008 system, links to SQL 2008 database, using the c # language as its developing code, according to different login user identity to different permissions, equipped with students, teachers, administrators three modes. Given the choice, add, delete, modify management, and other functions. Both saved artificial screening schedule time and improve the efficiency of the school work, kill two birds with one stone.
In this article, I mainly introduced the system each module content, including students, teachers, administrators, the three systems design, general design, and function implementation. For the present research status, and future development, software features have made more concrete. Hope to have seen the paper the opinions of teachers and students can give some advice.
