题目：精品课程在线学习系统的设计与实现
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。因为传统精品课程学习信息管理难度大，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精品课程在线学习系统，可
以解决许多问题。
精品课程在线学习系统实现的功能包括论坛管理，教学资源管理，课程留言
管理，课程收藏管理，公告信息管理，用户管理，试卷管理，试题管理，考试记
录管理等功能。该系统采用了 Mysql 数据库，Java 语言，SSM 框架等技术进行
编程实现。
精品课程在线学习系统可以提高精品课程学习信息管理问题的解决效率，优
化精品课程学习信息处理流程，保证精品课程学习信息数据的安全，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 of the
difficulty of traditional quality course learning information management, the low fault
tolerance rate, and the time-consuming and labor-intensive processing of data by
managers, an online learning system for quality courses has been specially developed
to solve this problem, which can solve many problems.
The functions implemented by the online learning system for excellent courses
include forum management, teaching resource management, course message
management, course collection management, announcement information management,
user management, test paper management, test question management, test record
management and other functions. The system uses Mysql database, Java language,
SSM framework and other technologies for programming.
The online learning system for excellent courses can improve the efficiency of
solving the problems of information management in the learning of excellent courses,
optimize the processing flow of learning information of excellent courses, and ensure
the security of learning information and data of excellent courses. It is a very reliable
and very safe application.
