摘要
网站建设是Internets应用的重要组成部分。因此教育部为大力发展信息化建设，提高教学质量，把精品课程建设定为《质量与工程》的先期启动项目。而《计算机操作系统》课程是我校软件学院的专业核心课程。因而开发一个操作系统精品课程网站是刻不容缓的。
系统是基于B/S的开发模式。而客户端视图层采用最为流行的RIA富客户端技术Flex，具有面美观，人性化，交换性强等特点；在后台的业务逻辑层使用的是以Java语言为支持的J2EE技术，由于Java语言具有面向对象和良好的跨平台性等特点，使的系统的分析设计和后期维护更加简单；同时，后台数据库使用了SQL2000作为数据库管理软件，使系统数据的安全性得到了有效的保证。系统主要实现的功能有，操作系统课程信息管理；教学资源管理，包括教师后台教学资源的上传，学生和游客资源的下载等；在线测试，包括管理题库的录入，和学生按照多种方式进行在线测试等。
本文简要介绍了操作系统精品课程网站系统所用到的主要的技术，如：MVC的分层思想，Flex/Flash技术，Flex和后台Java的通信技术，面向对象分析设计技术等；同时，比较详细的介绍了使用UML统一建模语言对系统进行分析设计的过程;并对系统中的关键模块的实现进行了详细的描述；最后对这个系统的开发进行了总结。

Abstract
Site construction is an important part of the application Internets. Therefore, the Ministry of Education to develop information technology to improve teaching quality, the fine course construction as the \and engineering,%up-front to start the project. The \operating system\course is my school School Of Software professional core curriculum. Thus, development of a course Web site is operating fine without further delay.
System is based on B / S of the development mode. The client-side view of layer of the most popular RIA rich-client technology, Flex, with a face beautiful, humane, and strong characteristics of the exchange; in the background of the business logic tier user Java language support based on J2EE technology, due to Java language with the object-oriented and a good cross-platform characteristics, etc., so that systems analysis and design and post-maintenance of a more simple; same time, the back-end database using SQL2000 as the database management software, allowing the system security of data has been effectively guaranteed. System is mainly to achieve the functions, operating systems courses information management; teaching resources management, including teachers, teaching resources and background of the upload, download resources, students and visitors, etc.; online testing, including the management of item bank of the entry, and students in a variety of ways in accordance with On-line testing.
