Study on the system architecture and applications of database gateway of VOD in CATV

针对基于XML的数据库网关(中间件)技术的设计和实现作了详细的介绍,分为数据接收、数据分析处理和数据回送3个模块进行论述,并结合其在有线电视节目点播VOD中的应用,在接收点播请求、分析处理请求和请求响应3个方面给出实现方案。

This paper gives a detailed account of design and implementation of the database gateway as a middleware, it integrates the XML and .NET technique into the design. We give the implementation solution from data reception request, request processing and request response, and an actual application is given to show the use of the database gateway.
