| Information is very important in current society. How to extract information of the data efficiently and how to integrate numerous and complicated network heterogeneous information are puzzles that face developers of system integration at present.At first, this paper analyzed the internal and external situation of the research methods of heterogeneous data in computer domain. XML-based RDF(Recourse Describe Framework) is introduced as well. Then heterogeneous data integration mechanism based on XML is lucubrated. Thirdly, integrated heterogeneous data integration method with RDF technology, a method of information semantic heterogeneous data integration based on XML&RDF is designed. And the system designed method which the system mainly employed and the main object semantic description are narrated in detail. Finally, cooperated with anexample----fire-fighting archive management system, this paper introduced theapplication of information semantic heterogeneous data integration method.The heterogeneous data integration method led the former XML heterogeneous data integration to high-level. In monomer enterprise system, the whole system is divided into five separate layers: resource layer, XML demonstration layer, XML&RDF layer, reasoning & broker layer, application layer. The system uniformed heterogeneous data in XML format via packer, and converted into RDF description format, then stored in RDF information semantic description bank, at last using XSL technology , the variety of heterogeneous data is displayed to users. Employing object-oriented and semantic method, the system is designed. And utilizing .NET frame structure, the design of system is realized. |
