进入数字化、信息化时代的21世纪,随着科学技术的进步,信息呈指数增长,知识和技术更新日益加快,原有的知识传播方式已经远远无法满足人们终身学习的需求,这使得我们迫切需要一种高效的知识传播方式。网络视频教学是一种新型的教学模式,将最大限度利用现有的教育资源,它是实现教育的大众化、现代化、终身化和国际化的新型教育形式。
本系统实现的是基于WEB,它涉及后台数据库、基本表与前台绑定操作。本系统使用ASP 3.0和Dreamweaver 2004软件为开发工具进行系统前台开发,数据库及基本表的建立使用Access 2003;此外,该系统与普通的视频系统的不同在于利用局域网实现教师和学生的双向教学,弥补了以往教学形式单一的不足。
论文主要围绕三个方面论述:ASP以及相关数据库编程,包括ASP的对象和组件的介绍、使用方法,以及ASP同ACCESS结合,通过数据库连接文件实现对数据库的管理等。在概要设计中描述了系统模块的划分,各个模块的关系及相关流程图。详细设计部分着重描述了一些主要功能模块的代码实现、关键技术和界面设计。

Enters digitized, the becoming an information based society time 21st century, along with the science and technology progress, the information assumes the exponential growth, the knowledge and the technology renews speeds up day by day, the original knowledge dissemination way already by far was unable to satisfy the people lifelong study the demand, this caused our urgent need one highly effective knowledge dissemination way. The network video teaching is one kind of new educational model, maximum limit will use the existing education resources, it will be realizes the education popularity, the modernization, the lifelong and the internationalization new education form.
This system realization is based on WEB, it involves the backstage database, the fundamental catalogue and the onstage binding operation. This system uses ASP 3.0 and the Dreamweaver 2,004 softwares carries on the system onstage development for the development kit, the database and the fundamental catalogue establishment uses Access 2003; In addition, this systematic and the ordinary video system differently lies in using the local area network realizes the teacher and student's bidirectional teaching, has made up the former teaching form sole insufficiency.
The paper mainly revolves three aspects to elaborate:ASP as well as related database programming. including ASP object and module introduction, application method, as well as ASP with ACCESS union,Through database connection document realization to database management and so on.Described the system module division in the outline design, each module relations and related flow chart. The detailed design partial described some main function modules code realizations, the essential technology and the contact surface design emphatically
Keywords:;Database;ASP;ACCESS;WEB
