【摘要】 随着信息技术的发展，数据仓库(Data Warehouse)技术己被广泛应用于现实生活的各个领域，这不仅大大提高了信息的使用效率，而且也为实际的生活带来了极大的便利。然而当前的数据仓库还存在着许多不足之处，它建立在传统的数据库管理系统(DBMS)平台之上、采用的是C／S(Client／Server)结构，这种结构的单一性暴露出许多问题，如建立和维护成本高、系统的协调性和兼容性差、可移植性不好、智能性不高等等。 而智能Agent正是当前国内外研究的热点，本文在分析了Agent的特性及众多优势之后，结合当前盛行的Web技术，提出了基于Agent的Web数据仓库思想。这种新型的数据仓库系统弥补了传统数据仓库的不足之处，它界面友好、使用方便，在实际应用中，可以大大减少数据传输过程中网络流量，合理实现异构数据源的数据集成，为数据仓库的开发起到一定的抛砖引玉的作用。论文研究的主要内容与成果包括三个方面： 第一，详尽分析了Web技术在数据仓库系统中的应用，在传统数据仓库系统基础上，引入XML技术，通过Internet对广泛分布的异构数据源进行整合，提出了一种新型的Web数据仓库模型。并研究了该结构的基本过程和功能。 第二，讨论了在Web数据仓库中引入Agent技术的重要性，详细探讨了将软件Agent引入到数据仓库及网络中各服务器端所实现的新型功能，以及在网络数据仓库中多Agent系统之间的协作机理。 第三，将系统应用到网上教学中加以实现，不仅提出了新型基于Agent技术的网上教学模式，而且对网上教学的协作机理和个性化评价进行了详细研究，最后提出了教学系统中智能选题的程序实现方法及多Agent之间协作的实现代码。更多还原

【Abstract】 With the developing of the information technology, Data Warehouse technology has been widely used in all kinds of aspects of lift, which not only improves the efficiency of the information using but also brings tremendous advantage to lift. Though there are some shortage in DW at present, which is based on traditional DBMS by adopting the C/S structure. In the simplex structure, much flaw, is exposed, such as the high cost, the bad harmony and compatibility , the ecumenical transplantation and the low intelligentizingoThough the intelligent Agent technology is the hotspot in the field of computer . After analyzing the character and the advantage of Agent, and combining with prevailing Web technology, this paper presents a thinking of web data warehouse System based on Agent. With its friendly interface and convenient usage, the new system can reduce the quantity of data transmission in web and realize the data integration of isomerous data source. All which has bring a new method for farther DW exploiture. This Paper probes into the above problems, the main contents and research productions include 3 aspects as follows:1. Detailedly analyze the application of Web technologies in DW. Based on traditional DW, By importing XML and correlative middle-ware and integrating isomerous source of widely distributing date by means of Internet, Pater presents a new model of Web DWo What’s more, we research basal procedure and function .2. Discuss the importance of intelligent Agent importing Web DW, at the same time, Detailedly discuss the new-style function brought by soft Agent importing DW and Web severs, furtherly explore the synergic mechanism among multi-Agent in Web DW.3. By applying the system to Web teaching and realizing, Pater presents a new-model of Web teaching based on Agent and researchs the synergic mechanism and the individuation evaluation in Web teaching detailedly. At last, presents the method and algorithm of intelligent choosing problem in teaching system and writes out some code of cooperation among multi-Agent.更多还原
