题目：学生网上选课系统的设计与实现
摘 要
如今社会上各行各业，都喜欢用自己行业的专属软件工作，互联网发展到这
个时候，人们已经发现离不开了互联网。新技术的产生，往往能解决一些老技术
的弊端问题。因为传统学生选课信息管理难度大，容错率低，管理人员处理数据
费工费时，所以专门为解决这个难题开发了一个学生网上选课系统，可以解决许
多问题。
学生网上选课系统可以实现教室管理，老师管理，课程管理，教学计划管理
选课管理，成绩管理，学生管理等功能。该系统采用了 Mysql 数据库，Java 语言，
Spring Boot 框架等技术进行编程实现。
学生网上选课系统可以提高学生选课信息管理问题的解决效率，优化学生选
课信息处理流程，保证学生选课信息数据的安全，它是一个非常可靠，非常安全
的应用程序。

Abstract
Nowadays, all walks of life in society like to work with their own
industry-specific software. At this point in the development of the Internet, people
have found that they cannot do without the Internet. The emergence of new
technologies can often solve the drawbacks of some old technologies. Because
traditional student course selection information management is difficult, the fault
tolerance rate is low, and the management personnel is labor-intensive and
time-consuming to process data, a student online course selection system has been
specially developed to solve this problem, which can solve many problems.
The student online course selection system can realize classroom management,
teacher management, course management, teaching plan management, course
selection management, grade management, student management and other functions.
The system uses Mysql database, Java language, Spring Boot framework and other
technologies for programming.
The online course selection system for students can improve the efficiency of
solving students' course selection information management problems, optimize the
student's course selection information processing process, and ensure the safety of
students' course selection information data. It is a very reliable and very safe
application.
