摘 要
互联网发展至今,无论是其理论还是技术都已经成熟,而且它广泛参与在社
会中的方方面面。它让信息都可以通过网络传播,搭配信息管理工具可以很好地
为人们提供服务。针对学生选课信息管理混乱,出错率高,信息安全性差,劳动
强度大,费时费力等问题,采用学生选课系统可以有效管理,使信息管理能够更
加科学和规范。
学生选课系统在 Eclipse 环境中,使用 Java 语言进行编码,使用 Mysql 创建
数据表保存本系统产生的数据。系统可以提供信息显示和相应服务,其管理员管
理专业,教师,学生,课程,查看学生选课以及学生成绩信息。教师查询学生,
查询课程,审核学生选课信息,为学生学习的课程进行成绩打分。学生参与课程
选课,查询选课信息,查询已选课程的成绩信息。
总之,学生选课系统集中管理信息,有着保密性强,效率高,存储空间大,
成本低等诸多优点。它可以降低信息管理成本,实现信息管理计算机化。

Abstract
Since the development of the Internet, both its theory and technology have
matured, and it has been widely involved in all aspects of society. It allows
information to be disseminated through the Internet, and it can serve people well with
information management tools. In view of the chaotic management of student
selection information, high error rate, poor information security, high labor intensity,
and time-consuming and labor-intensive problems, the student selection system can be
used for effective management, making information management more scientific and
standardized.
The student selection system is in the Eclipse environment, using the Java
language for coding, and using Mysql to create a data table to save the data generated
by the system. The system can provide information display and corresponding
services. Its administrators manage majors, teachers, students, courses, and view
student selections and student performance information. Teachers inquire about
students, inquire about courses, review students' course selection information, and
give scores for students' courses. Students participate in the course selection, query
the course selection information, and query the grade information of the selected
course.
In short, the student course selection system centralized management information
has many advantages such as strong confidentiality, high efficiency, large storage
space, and low cost. It can reduce the cost of information management and realize the
computerization of information management.
