摘要
在计算机应用日益普遍和广泛的今天,计算机科学也日益成熟,它已进入到人类的各个领域并发挥着越来越重要的作用。网上选课系统是教育单位不可缺少的部分,教师在网上公布自己的可选课程、可选人数,学生就可以不受时间和空间的约束,在教师规定的时间内、在自己方便的地点进行选课。这样既提高了选课的效率,减少了教师和管理人员的工作量,又方便了学生。若出现错选或重选的情况,学生也可以通过选课系统进行更改,而不用再去找教师更正。
本文通过分析B/S结构的特点并结合城固师范公共选修课的实际情况,提出了基于B/S结构的城固师范网上选课系统的基本设计思想,通过该系统,使学生可以方便地进行网上选课。
本文主要从以下几个方面对基于B/S的城固师范网上选课系统进行研究和设计:
1) 网上选课系统主要包括管理员登录模块、教师登录模块和学生登录模块。
2) 对网上选课系统进行分析与设计,构架出选课系统的基本框架,得出各模块所要实现的功能。
3) 介绍了基于B/S结构的网上选课系统的设计方案和关键技术。

Study of Chenggu Normal Course-Selection System Based
on B/S
Abstract
In computer applications become increasingly common and widespread today, computer science has become more mature, it has entered into various fields of human and play an increasingly important role. Course-Selection System Based on B/S is an essential part in education field. Teachers posted on the optional courses, the number of options on the web, students can select the courses in their convenient locations and time. This will not only improve the efficiency of the course-selection, but also convenient to the teachers and the students. If a wrong course-selection is occurred,students can make changes through the system .
By analyzing B/S structure and the characteristics and the actual situation of Chenggu Normal ,we get the basic designing idea. So the students can easily select courses on line.
This paper mainly study and design the College Students Course-Selection System Based on B/S from the following aspects:
1) The College Students Course-Selection System Based on B/S mainly include administrator login module, teachers login module and students login module.
2) The author builds up the basic framework of Course-Selection system online and drawn the functions of every modules want to achieve by analyzing and designing the Course-Selection system online.
3) Finally, it depicts the design proposal and critical technologies of Course-Selection System Based on B/S.
Key words: B/S structure ; select courses online ;Course-Selection System ; access database
