The Study Of Web Data Warehouse System Based On Agent

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.
