Agent技术在Web数据仓库结构中的应用研究

针对基于Web的数据仓库体系结构存在的问题,在该体系结构中引入软件Agent技术,运用移动Agent技术来解决传统方法难以解决的一些主要问题,提出了一种基于Agent的Web数据仓库系统体系结构。文中发挥数据仓库技术和Web技术结合的优势,重点研究了Agent技术在Web服务器端的应用,在把有用的Web数据集成并入到数据仓库中这一目前的研究热点问题中,提出了基于Agent技术将HTML页面转化为XML数据源的解决方案。此外,文章分别研究了应用服务器端和数据仓库系统中的Agent技术的应用,并提出了将Agent技术引入后实现基于Web的数据仓库体系的关键技术。

Study on Application of Agent Technology in the Web-Based Data Warehouse System

In order to resolve the shortages and problems of the Web-based data warehouse system that traditional method can't solve, by introducing the software Agent technology to every part in the configuration, the author pro- poses a Web data warehouse system configuration based on the Agent. Firstly, by taking the advantage of the combi- nation of Web technology and data warehouse technology, the application of Agent technology in the Web server ter- minal is deeply researched in this paper. To the important issue that how to integrate the useful Web data to data warehouse, the method is proposed to transfer the HTML page into XML data source combined with Agent technolo- gy. In addition to, the application of Agent in the application server terminal and in the data warehouse system are an- alyzed respectively, and the key technologies to realize the Web-based data warehouse system based on Agent are pro- posed.
