随着IT技术的发展，人们的日常生活、工作都已经离不开计算机。未来的社会中人们的生活和工作将越来越多的依赖于数字技术的发展，越来越数字化、网络化、虚拟化。从计算机的发展历程以及目前的应用状况和发展趋势来看，可以充分地相信计算机技术将很大程度上的改变我们的生活方式和工作方式，甚至对社会的价值观也将产生影响。

毕业设计信息管理系统是在Visual Studio.Net 平台上运用ASP.NET技术来实现的。其主要功能有：系统管理，学生信息管理，教师信息管理，教务员信息管理，教师网上出题，学生网上选题，教务员查看选题情况等。论文在撰写过程中，力求将理论与实践应用相结合，对各种理论进行阐述的同时配合系统从实际应用和操作技巧上加以说明，希望能够更充分地体现到这些知识与技术在本系统中的应用与实现。

Abstract

 

With the development of IT technology, people's daily lives and work have been inseparable from the computer. People live and work in the future society will be more and more dependent on the development of digital technology, more and more digital, network, and virtualization. From the course of development of the computer and the current application status and development trend, we can fully believe that computer technology will largely change the way we live and work, and even the values of society will have an impact.

    The graduation project information management system using ASP.NET technology to achieve in Visual Studio.Net platform. Its main functions are: system management, information management students, teachers, information management, information management of the Senate members, teachers' questions online, student online topics, the Senate member to view topics and so on. In the process of writing, the paper sought to theory and practical application of the combination of the various theories described in conjunction with the system to illustrate practical applications and skills, want to be able to more fully reflect the knowledge and technology in this system application and Implementation.
