摘 要

随着网络技术的发展及计算机的日益普及，电子政务的不断发展完善以及其领域的不断拓展，现代远程教育作为一种新的教学手段已经开始进入我们的生活，给传统的教育模式带来新的变革，并对教育的发展形成了新的推动力，而作为远程教育关键环节之一的在线考试也逐渐成为了一个重要的研究领域。同时，在线考试具有的智能化、自动化、高效化、科学化等诸多优势，也使其成为传统教育考试发展的必然趋势。
基于B/S模式，结合功能强大的Dreamweaver MX网页设计工具，以ACCESS 2000作为后台数据库，采用内嵌HTML语言的ASP（Active Server Pages）编程技术开发了无纸化网上考试系统。该系统实现了对题库和考生的自由管理，可自动生成试卷、自动判卷，以及完成相关的系统维护。其中，系统维护主要包括题库管理、考生管理、新闻发布、科目管理和考试计划管理。该系统能够突破时空的限制，让考生在规定时间段内的任意时间、任意地点通过网络参加考试，给考生带来了极大的方便，而且节省了许多人力、物力资源，大大提高了教学效率。
首先阐述了电子政务发展及背景以及网上考试系统的现阶段状况，也简要介绍了ASP、ACCESS 、VBScript、JavaScript等相关的理论知识。接着详细介绍了系统的需求分析、总体设计、数据库设计及系统功能的实现。最后概括了系统的主要特色，指出了系统存在的不足之处，并对系统的开发做出了全面的总结。

Abstract

With the development of network technology and the popularity of computers, the modern education of distant learning already enter our life as one kind of new teaching means. It brings a new revolution to traditional education patterns, and forms the new motive forces to development of education. The online examination being one key link of distant learning has also become an important research field gradually. At the same time, a lot of advantages such as intelligence, automation, high efficiency and science have made the online exam becoming the inevitable trend of the traditional education.
Adopting B/S mode, using powerful web page designing implement of Dreamweaver MX and using ACCESS 2000 to be the backstage database. The system adopts inner ASP（Active Server Pages）programming technology within HTML language without papers to achieve examination online. System accomplishes management freely on question library and examinee, the system can generate examination paper and assess examination paper automatically, it also manages system upkeep.The system upkeep is composed of question library, student management, announcing news, subject management, plan of examination. By the system, students can break through the limitation of the time and space and take part in the examination in the different location during the given time section using local Internet. It not only brings the most convenience to student, but also saves a lot of manpower and material resources. It enhances teaching efficiency greatly.
Introducing the background and development of exam system online at first. Then simplely introduce relative theoretical knowledge of ASP, ACCESS, VBScript and JavaScript. And detailed introduce the systematic need analysis, population design, database design and system function realization. Finally, summarize the systematic main characteristics, point out the defects of the system and make the all-round summary to systematic design.

Key words: ACCESS 2000; ASP; HTML; VBScript; JavaScript; Electronic government affairs; Exam System Online; B/S mode
