毕业论文--基于Web的毕业设计管理系统的设计与实现.doc

摘 要 本系统是针对现代高校计算机技术的发展，为了应对以往毕业生毕业设计中遇到的工作效率低，交互性差等问题而采用软件工程的设计思想设计的。本文的基础就是利用ASP.net技术与Web数据库的结合，开发出的一个基于Web技术的B/S结构的毕业设计管理系统。 首先，本文探讨了数据库运行的体系结构，介绍了浏览器/服务器模式的工作方式及特点；比较了主机/终端、客户机/服务器和浏览器/服务器等三种模式各自的优缺点。比较结果表明，浏览器/服务器模式继承了客户机/服务器模式的优点并克服了它的缺点，不受操作系统和硬件的制约，而且能防止“胖客户机”现象的发生，比较容易实现不同网络间的连接。浏览器/服务器模式是目前广泛使用的主体结构。因此，我们开发的本系统也将采用了浏览器/服务器模式。在此基础上，本文还探讨了实现Web数据库的不同方法。本文重点还讨论了如何利用ASP.net技术和ADO.net对象来实现对数据库的访问方法，给出了设计细节和具体步骤及其方法。 本次设计是应用ASP.NET技术实现网络环境下的毕业生毕业设计管理。利用Microsoft Visual Studio.NET工具结合使用SQL Server数据库，ASP.NET、C#、ADO.NET等技术的工作原理及特点，并以此为理论技术依据阐述了基于Web的毕业设计管理系统的结构设计和具体的实现过程。 关键词:B/S结构，C/S结构，Web数据库，三层式结构，毕业设计管理系统，A The Design and Realization of Graduation Project Management System Based on Web Abstract :This system is designed in allusion to the development of modern computer technology in universities and colleges. It adopts the design ideology of software engineering, in order to answer the problems that had been faced by the graduates in their graduation projects, such as low work efficiency, and poor interaction. The foundation of this text was combining the skill of ASP.net with Web Database, and exploiting a management system based on the skill of Web and the structure of B/S. Firstly, this text discusses the system and structure run by database, introduces the working and characteristic of the B/S pattern, and also compares with three kind of patterns respective advantage and disadvantage among Mainframe/Terminal，Client/Server and Browser/Server. The result indicates that the mode of B/S inherits the merit of C/S, and conquers its shortcoming. This mode is not conditioned by OS and hardware, and also can prevent the fat client happening, even it can easily connect different networks. The mode of B/S is the main structure used widely at present. Therefore this system adopts the mode of browser/server. On this foundation, this text discusses the different ways to actualize Web Database. The discussion centre on how to use the ASP.net technology and the object of
