I
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《离散结构》课程教学信息管理混乱，出错率高，信息安
全性差，劳动强度大，费时费力等问题，采用《离散结构》课程辅助教学平台可
以有效管理，使信息管理能够更加科学和规范。
《离散结构》课程辅助教学平台在 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，本系统可以实现课程管理，课程作业管理，作业提交管理，课程提问管理，
课程回答管理，课程问卷管理，教研活动管理，论坛管理等功能。
总之，《离散结构》课程辅助教学平台集中管理信息，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 the teaching
information of the "Discrete Structure" course, high error rate, poor information
security, high labor intensity, and time-consuming and labor-intensive problems, the
use of the "Discrete Structure" course auxiliary teaching platform can effectively
manage and make information management more scientific and standardized.
The "Discrete Structure" course auxiliary teaching platform 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. The system can realize the functions of course
management, course homework management, homework submission management,
course questioning management, course answering management, course questionnaire
management, teaching and research activity management, forum management, etc.
In short, the "Discrete Structure" course auxiliary teaching platform 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.
Key Words："Discrete Structure" course auxiliary teaching platform; Java language;
