net高校教材征订xns程序--论文.doc

摘 要 随着近几年来微机技术、网络技术及相应软件技术的迅猛发展，学校的教材、管理等工作已越来越离不开计算机了。本系统—征订教材是针对现今教材模式复杂，管理繁琐这一问题开发、研制出来的。 本系统基本遵循软件工程方法论进行系统分析、总体设计、详细设计和软件测试。采用ASP.NET 技术作为创建应用程序的方式，以C#作为编程语言，采用SQL Server 数据库作为后台数据库。它是基于Browser/Server结构下形成的数据驱动的Web应用程序。 实现了管理员对系统用户管理、个人资料管理、教材征订管理、数据备份的维护；系主任角色对修改个人资料、教材征订管理；教师角色可以查看教材征订、修改个人资料。 关键字： C#.NET； SQL Server 征订教材 ABSTRACT With the computer technology in recent years, network technology and corresponding software technology, the rapid development of the teaching, management work has become increasingly inseparable from the computer. The system - data structure courses online teaching is the teaching model for todays complex and complicated issue management development, research and out. The system basically follows the software engineering methodology for system analysis, design, detailed design and software testing. Using ASP.NET technology as a way to create applications to C # as the programming language, using SQL Server database as the backend database. It is based on Browser / Server structure, formed under the data-driven Web applications. Administrators realized the class information, teacher information, student information, message boards, maintenance; role of teachers teaching courseware, educational software, teacher comments to students assignments, online exercises and online Q As management; student role can view the courseware , educational software, teacher comments to students assignments, online exercises and online Q As view and made the message board, back and view it.
