在线学习平台的设计与实现
摘 要
在线学习平台，是一个利用因特网作为平台传送教学内容，实施网上教学，进行网上交流和学习的信息系统。构建在线学习系统平台，可以克服传统课堂教育的局限性，形成一种主动的、协作的、开放的教学模式，既有生动形象和资源广泛的优点，又具有能相互访问、双向交流，不受时空限制的优良特性。
系统结合实际需求，采用 B/S模式，以tomcat为应用服务器，并结合JSP开发技术及mysql数据库来进行开发，实现了资料下载、在线学习、在线测试、在线答疑等功能。本文从系统开发目的及意义、需求分析、开发平台的选择、系统模块建立、数据库设计、各个功能模块的实现等方面详细介绍系统的设计与实现方法，并采用数据流程图、E-R图及程序流程图对系统开发过程进行了辅助说明。
在线学习平台经测试后所有功能均能正常运行，它将为人们的学习带来极大的方便。

Abstract
Learning Online Management System（LOMS）is a information system which makes use of the Internet as a platform to transfer the teaching contents, make intercourse online and study. To construct the platform of LOMS can overcome the limitations of the traditional classes, and form an active, cooperative, and open instruction type of advantages in vivid images and vast resources, and of qualities in mutual accessing, double communication, not restricting by time and space.
This system links with the practical demand and uses B/S model with the Tomcat as the application server, and combines with the JSP technology and the DBMS of mysql, which realizes the functions such as long-distanced transmitting the homework, online correcting, online testing, online answering, discussing, and online intercourse. Through the purpose and the significant system, and the analysis of demand, the selecting of platform, the establishing of system module, the design of data-base, and the realization of all each function module, this text particularly introduces the design of the system and the methods, and narrates in assistant using the data flow chart, E-R chart, and program flow chart.
The LOMS will bring people huge convenience in learning after all functions are tested and can work normally.
