JAVA language provides highly efficient and stable operating environment toenable online examination system interms ofspeed, ease ofuse, orinthe data throughput capabilities are outstanding, especially inthe system concurrency, stability, far ahead ofthe other based onother similar test system environment. Online examination system back-end front-end applications and management systems are used B/S-Mode l, Front-end system using ASP, database, SQL language toreplace the traditional way ofXML parsing and effectively solve the bottleneck ofslow XML parsing, not only improves the security ofthe system, and also enhance the user experience can access and browser management, with ahigh degree ofscalability, stability and reliability. 【关键词】 ASP 技术数据库 SQL 语言 B/S 模式【 Key words 】ASP technol
