摘要

 随着科学技术的不断提高,计算机科学日渐成熟,其强大的功能已为人们深刻认识,它已进入人类社会的各个领域并发挥着越来越重要的作用。学生选课系统作为一种现代化的教学技术，以越来越受到人民的重视，是一个学校不可缺少的部分, 学生选课系统就是为了管理好选课信息而设计的。学生选课系统的将使选课管理工作规范化，系统化，程序化，避免选课管理的随意性，提高信息处理的速度和准确性，能够及时、准确、有效的查询和修改选课情况。[1]
 系统实现了对课程的基本信息和学生选课、学生和教师用户进行管理。系统对学生角色提供个人信息查看、选课管理以及其他功能；对教师提供查看自己所担任课程的课表和选该门课程的学生信息；提供给管理员以下功能：查看所有课程、学生、教师的信息并可以对它们进行管理（添加、编辑、删除），以及实现新闻的发布并修改。[7]

 ABSTRACT

 With the improvement of science technology, the computer science becomes gradually mature, people have already deeply understood its strong function, and it has already got into each realm of the human society to exert a more and more important function. The student selecting system, a modernizing teaching technology, pays much more attention by people. It is indispensable part for a school. The student selecting system is for the sake of managing to the information of selecting courses. The tendency of student selecting system will edify the selecting management, it would be more systematical and procedural in future work. We try to avoid the random work, promoting the accuracy and speed of the processing information, so that we can check the information of selecting course with a convenient and efficient form.
 The system carried out the management of basic information of course, the student selecting course, the student and the teacher's customer. The system provides a function, which is good for students to check their personal information and the management of selecting course, to the characters of the students. And for the teachers, it is convenient to look into the curricular lesson that he hold and the Student's information that chose the course. At last, it is good for manager to check all the information of the lessons, students and teachers. Furthermore, it can carry on a management (increase, edit, delete) to them, and carry out the renounce of the news.
Key words: Select course, the renouncement of course information,、Mysql、JSP
