优课网上商城的设计与实现.pdfVIP

摘 要 现如今，互联网带给我们无穷无尽的消息，教育受到互联网的影响后使得教育模式 发生了变化，线上教育也成为了当前的一种教育趋势。网络为大家提供了一个学习，交 流的平台，将最先进的知识放在网络上供大家学习与交流，使得线上教育成为以后极具 潜力的一种教育模式。 本系统是基于软件工程的线上教育网站的设计与开发。本系统采用了模块化管理， 针对不同的对象，不同的的用户有不同的处理方式。例如教师主要是课程上传，资料上 传，而学生则主要是进行浏览，购买课程。管理员则主要对信息进行增删改查。 本项目是采用软件工程的方法设计并实现的，过程中结合线上教育的特点，对业务 流程进行适当的改动，实现了信息集中管理、分散操作、信息共享等功能。在系统设计 部分，本文详细讨论了选课系统的体系结构，分析每个模块中的实体，设计数据库表。 然后将这些表创建，组成完整的数据库。本文最后介绍了系统的性能测试与输入输出结 果。 关键词：在线教育系统　　需求分析　　系统体系结构　　软件工程 I Abstract Nowadays, the Internet brings us endless information. Influenced by the Internet, education mode has changed, and online education has become a current educational trend.The Internet provides a platform for everyone to learn and communicate. The most advanced knowledge is put on the Internet for everyone to learn and communicate, which makes online education become a promising educational model in the future. This system is based on the design and development of online education website based on software engineering.The system adopts modular management, for different objects, different users have different ways of processing.For example, teachers mainly upload courses and materials, while students mainly browse and purchase courses.The administrator is mainly to add or delete the information to check. This project is designed and implemented by means of software engineering. In combination with the characteristics of online education, appropriate changes are made to the business process to realize the functions of information centralized management, decentralized operation and information sharing.In the system design part, this paper discusses the system architecture of course selection in detail, analyzes the entities in each module, and designs the database table.These tables
