摘要
随着网络技术的发展,在线训练与考试已成为各行业、各机构人才培养与评价的重要途径。通过分析在线训练与考试任务的功能需求,设计在线训练与考试系统采用B/S架构,结合.NET开发技术和SQL Server数据库。系统功能涵盖用户授权与登录管理、试题库管理、组卷管理、考生管理、考场管理、阅卷管理、成绩管理等。作为系统设计的重点,组卷管理采用遗传算法实现作为组卷策略之一;数据库安全设计采用动态密钥分配方式确保题库认证安全,采用XML文档对称加密方式防止试题失控。
With the development of network technology, most industries and organizations have selected online training and examination as an important way of talent training and estimate. By analyzing the function requirements of online training and examination tasks, the on-line training and examination system is designed, which uses B/S structure and combines with the technology of. NET and SQL Server database. The system＇s function includes user authorization and access management, question warehouse management, Test paper management, test management, examination room management, marking management, performance management, etc. As the focus of system design, test paper management uses genetic algorithm as a test paper organization strategy. Database security design adopts dynamic key allocation method to ensure that the database authentication, using XML document encryption methods to prevent item out of control.
