ASP+SQL Server 2000点播系统分析与设计

随着科学技术的不断发展，网络在我们的日常生活中正发挥着它重要的作用。现在，网络上传递的信息种类越来越多，从最初的文字信息发展到目前的文字、图象、声音、视频、动画等几乎所有种类的信息。因为需要传递的信息种类的增多，尤其是需要同时传递多种信息的时候，对计算机网络的数据传输技术也提出了新的要求。在不断提升网络带宽的同时，网络多媒体技术也在不断地发展，包括数据的压缩编码和用于发布媒体的网络技术。在线点播系统就是近年来出现的比较新颖的运用流媒体技术的网络多媒体形式。比如百度MP3，QQ163music，如何有效地提高在线点播系统对音频，视频资源的利用效率，使其能够优质、高效、灵活地为我们的娱乐和悠闲生活提供服务，这就是我研究这个课题的意义所在。
本论文根据网络音乐的实际情况，通过对网站有关音乐媒体发布事项的一番调查与分析，在用户对音乐需求的解析基础上，明确了在线点播系统要实现的具体功能，并阐述系统的结构设计和功能设计，从而实现一个小型音乐网站的设计与应用。还介绍在线点播系统的应用和功能需求,设计了一个基于B/S模式的界面和以SQL Server 2000作为后台数据库的在线点播系统。并根据系统的具体要求和需要实现各模块功能。
该系统主要实现前台点歌模块和后台管理模块。前台点歌模块有以下功能：用户注册、分类查找、点播、试听；后台管理模块主要功能是添加、删除、修改歌曲库中的歌曲信息。本系统的主要技术要点有两个——在线点播歌曲技术和发送邮件技术。掌握了这两个技术就可以轻松实现在线点播系统了。在本系统中使用的内嵌播放器是RealPlayer，并通过JMail组件发送邮件，系统中创建过程SendMail，调用过程发送邮件。

Abstract
With the development of science and technology, the network in our daily lives it is playing an important role. Now, the type of the message on the network is raising, from the initial text messages to the current text, images, audio, video, animation, almost all types of information. Need to pass the kind of information because of the increase, in particular, need to also pass on a variety of information when the computer network's data transmission technology is also put forward new demands. Continuously improve network bandwidth, the network is continually developing multimedia technology, including data compression and network technology for the distribution medium. Online on-demand system is relatively new in recent years the use of streaming media technology multi-media format. For example 163music, QQmusic, how to effectively improve the online on-demand system for audio, video, resource use efficiency to enable high-quality, efficient and flexible for our entertainment and leisure is to provide services, that is why I study the significance of this issue.
The thesis actual situation according to the network through the site's media release relating to matters of some research and analysis, the analytical needs of users of music based on the clear online on-demand system to achieve specific functions, and described the system Design and functional design in order to achieve a small music website design and application. Also introduced online on-demand system, application and functional requirements, designed based on B / S mode interface and to SQL Server 2000 database as the back-line on-demand system. And according to the system to achieve the specific requirements and needs of functionality of each module.
The system module to achieve foreground and background song management module. Reception song module has the following functions: user registration, classification to find, on demand, listen; background management module main function is to add, delete, modify the song in the song information database. The main technical points of this system, there are two sides—— on-line demand technology and online technology to send messages. Master of the two technologies can be easily had online on-demand system. In this system, using the embedded player is RealPlayer, and through the JMail component to send mail, the system created in the process of SendMail, call the procedure to send mail.

Key words: Online on-demand system, ASP,Dreamweaver,SQLServer2000
