基于.NET网上考试系统的设计与实现

详细论述采用.NET技术,在B/S模式下实现在线考试系统的研制过程以及关键技术。系统采用XML作为WebService数据交换的格式,其逻辑都是在应用服务器上实现,采用WebService方式远程调用,成功地解决了旧有的考试系统扩充性不强、开发部署困难、使用不便等缺点。研究了将网络技术应用于考试中的实际问题,探索了利用网络进行远程考试的一些方法。该系统通过压力测试证明具有高度的可靠性,不仅可胜任高压力下的应用,而且可在适当的时候轻易地扩展到分布式应用。

Design and Realization of Internet Exam System Based on .NET

The key technique and research process of IES (internet exam system) based on the mode of B/S with .NET technology are presented. Web service data exchange is realized by the means of XML. The logic of test system online is realized on the application sever and can be transfer by the means of web service. The problems such as expansion insufficiency, difficulty in development planning, and using inconveniently of the current IES are resolved successfully. The practical problems in the processing of IES developing by the means internet technology are investigated. Some methods of test online by the means of internet are discussed also. The pressure of the system is tested, and the reliability of the system is testified. The IES can be used under the high pressure. The IES can also be expanded to distributing application.
