C#计算机实验课在线答疑系统设计(答辩PPT)
摘要：网上答疑系统为基于ASP.NET与C#技术的WEB应用程序，并以互联网为传播媒介来实现远程教育的一个教学平台。系统主要论述了其设计开发的基本过程，设计开发中主要运用了ASP.NET技术与C#语言、 SQL等相关技术，根据面向对象开发原理，采用了基于B/W/S三层体系结构的开发模式系统。以IIS为服务器，SQL server 2005为数据库平台，提供一个师生之间相互交流、相互探讨的网络空间,使学生在获取知识时更具有主动性。本系统包括即时答疑的管理与控制，文件资源的共享管理，问题及疑问留言解答的管理，后台数据库信息的管理文护等这些基本模块。

Experimental computer courses o nline Q & A System Analysis and Design
Abstract: Online Q & A system based on ASP.NET and C # technologies WEB applications, and Internet media to achieve a long-distance education teaching platform. Focuses on system design and development of its basic processes, design and development of the main use of ASP.NET technology and C # language, SQL and related technologies, in accordance with the principle of object-oriented development, based on the use of B / W / S three-tier architecture system development model. To IIS server, SQL server 2005 database platform to provide a mutual exchange between teachers and students, to explore each other in cyberspace, so that when students acquire knowledge in a more proactive. The system includes real-time Q & A management and control, file-sharing management resources, problems and answer questions about the management of message, the background database information such as the management of the maintenance of the basic module.
