The Research And Realizing Of The Virtual Database For Enterprise Information Integration

With the development at full speed of the information technology, the application of information integration technology in the enterprises is more and more extensive. However, the data-collect and the face-to-application integrated methods of traditional information integration can not satisfy the requirement of the increasable day by day data and flexibility aspect. All these make virtual database (VDB) emerging, as the times require. But the internal research of VDB still in primary stage. SO we carry on the VDB correlation study, design and realize a basic virtual database system.Through the study and inquisition for the virtual database technology and its application in the enterprise information integration system, this subject puts forward the architectural structure of the virtual database for enterprise information integration. Except supporting the integration between relation mould databases—SQL SERVER, this system also supports the integration between SQL SERVER and LOTUS NOTES, which is often used in the office automation. All these satisfy the needs of the general enterprise information integration. At the same time, this system provides the nimble disposition method. When developing enterprise information integration system, user can expediently configure the needed data sources and the authorized roles of the data sources through the configure window. This can simplify the development work greatly and reduces the period of the system development. The virtual database system is realized by WEB SERVICES technology so that the application system can use the virtual database system by transferring the system's WEB SERVICES service end.This paper basing on the analysis of virtual database and the data integration research's present situation, and the foundation of each synthetically correlation technique character, detailed expounds the architectural structure, settlement scheme and implementation tactfully of the virtual database system for enterprise information integration. The structure and organization of this paper is as follows: the first three chapters introduce virtual database technology and the architectural structure, this kind...
