【摘要】 进入信息时代以来，互联网正在深刻地、迅速地改变着我们的生活、工作和学习。我国目前正处在教育供需矛盾突出阶段，教育软件严重不足，教师资源短缺，学习人数逐年快速增长。利用网络开展e-Learning已经成为社会关注的热点，网络备课就成为e-Learning的基础和关键。本文基于WEB的备课系统的现状分析入手，结合WEB开发的特点和软件工程的思想，进行了较为详细地系统分析，在此基础上论述基于WEB备课系统的设计思想、总体结构和功能，以及实现方法和技术。系统采用三层体系结构，注意良好的可扩展性，采用模块化设计方法，将其划分为教师管理模块、课程管理模块、文件管理模块、留言管理模块、创建课程模块、在线备课模块、上传文件模块、配置课程模块等功能模块。本系统的前端开发工具是VS．NET，后台语言为C#，后台数据库选用的是大型关系型数据库SOL SERVER 2000。总之，通过本文的研究，在比较各种基于Web的备课系统的基础上，提出了一种基于Web的备课系统设计思想和方案，研究了基于Web的数据库开发中常用的主要技术及其实现方法和过程，并最终实现了一个具有一定使用价值的基于Web的备课系统。解决了我们当前应用需求，并提出了今后进一步的研究工作。更多还原

【Abstract】 We are now in a great new era of information. Our life-style, our work and our Study are changing rapidly. The lack of the education software, the lack of the teacher and the increasing of the student population is the main situation of our country. Making use of the network to develop the e-learning system has been a hotspot in the today society. Network Preparation Lesson becomes the base and key of e- learning.In this paper we first analyze the condition of the web-based Preparation Lesson System. By combining the characterization of web-based development and the thoughts of software engineering. We analyze the request of system in detail, and then discuss the design thought global structure and functions of the web-based Preparation Lesson System.The system adopts three-ply structure model, regards well expansibility, according to the method of module. All system is mainly composed of eight modules: the module of managing teacher, courseware management, file management, message management, creation course, online preparation lesson, loading file, course configuration.The foreparts explore tool of the system is VS.NET, the back-end computer language of the system is C# and the back-end database of the system is great relational database—SQL SERVER 2000.In a word, in this paper, after comparing various web-based Preparation Lesson System, we propose a designing thought and a design scheme, study the main technology of web-based database development and develop a web-based Preparation Lesson System which having some value, and advise some task for next study.更多还原
