Abstract
在线考试系统采用多层结构,基于 Web平台开发适用于多种操作系统及主流数据库。JAVA语言为在线考试系统提供了高效稳定的运行环境,使在线考试系统无论在运行速度、易用性还是在数据吞吐能力方面都表现卓越,尤其是在系统并发性、稳定性方面,遥遥领先于基于其它环境的其它同类考试系统。在线考试系统的前端应用系统和后端管理系统均采用 B/S 模式,系统前端使用了ASP技术、数据库技术、SQL语言等来代替传统的XML解析方式,有效解决XML解析速度慢的瓶颈,既提高了系统的安全性,又提高了用户体验可以通过浏览器进行访问和管理,具有高度的可扩展性,稳定性与可靠性。
Online examination system using multi-layer structure, based on Web platform suitable for a variety of operating systems and mainstream database. JAVA language provides highly efficient and stable operating environment to enable online examination system in terms of speed, ease of use, or in the data throughput capabilities are outstanding, especially in the system concurrency, stability, far ahead of the other based on other similar test system environment. Online examination system back-end front-end applications and management systems are used B / S-Model,
Front-end system using ASP, database, SQL language to replace the traditional way of XML parsing and effectively solve the bottleneck of slow XML parsing, not only improves the security of the system, and also enhance the user experience can access and browser management, with a high degree of scalability, stability and reliability.
