Researches And Implementation Of The Intelligent Query In Heterogeneous Data Integration System

With the quick development of computer technology and network technology, the data on network grow in exploding way. These data have obvious heterogeneous property. Most search engine and some integrated software treat the query of these heterogeneous data often could not play biggest role. The resuit. also often has only "scope" but no "depth" and exists plenty of rubbishes. Query mechanism is inflexible and hasn't point. The intelligent query problem of heterogeneous data has become the bottleneck problem of network sharingBased on the heterogeneous data integration prototype system SORE, a kind of intelligent query platform IQP is researched and implemented. In order to improve the Intelligence, in the research course of this platform. Agent and mobile Agent technology are led into.This paper includes six parts mainly. In the first part, it is introduced that the background of project, application prospect and meaning, my major job in the research course and innovation. Second part introduces from three angle the current situation of heterogeneous data query both at horm: and abroad The part of 3rd elaborates the design scheme of intelligent query platform IQP in detail How to apply Agent technology and mobile Agent technology in IQP is introduced in the fourth part. The part of 5th introduces the realization and system testing of intelligent query platform IQP. The last part is conclusion.
