基于ASP．NET学生选课系统的设计与实现

摘要

介绍ASP．NET、B／S三层架构模式等相关技术，并利用该技术开发了学生选课系统．该系统的开发工具选用微软Visual Studio．NET，开发前台界面采用CJHJ程序设计语言，数据库的设计采用SQL Server 2005开发工具，并通过ASP．NET和ADO相结合的方式访问后台数据库．使用该系统能够克服以往选课系统中学生无法提前全面了解选课信息的不足，引导学生结合自身特点制定选课计划，实现理想选课并最终实现学生网上选课的全过程．%The single sign on of system model and the design of ticket were discussed in detail. One implementation method of single sign on based on Session was introduced, achieving Session share through mechanism of serialization and deserialization under the ASP. NET environment. The message of Session and the user＇ s role were written into the XML file as a ticket. The Web services system downloads this ticket from Certification Center and desterilizes the ticket to implement the single sign - on. In the environment which prohibits the use of Cookie in the client the single sign - on system and cross - domain access can be achived.
