Research On Integration Technology Of Geophysical Professional Database

Data integration technology is to solve the key technology of data exchange and datasharing between the current heterogeneous data system,through the study of geophysicalprospecting professional database of data integration technology,this paper discusses theapplication of data integration technology and theoretical basis of data integration technologyfrom five aspects.1. theoretical basis of data integration technology. Mainly includes the explanation of theconcept of data integration, expound the functions and benefits of data integration technology,classify data integration technology, the architecture of data integration, the core of dataintegration technology is ETL,and the data integration process will face a variety of problems.2. Data integration technology application of geophysical prospecting professionaldatabase system. Through the research on the architecture of geophysical prospectingprofessional database,expound the specific application of data integration technology in thisdatabase.Research on the technology of actualizing process of data integration, includingmetadata technology、data mapping and data exchange technology.3. Research on the application of data mapping in the data integration process. The mainexpounds in what areas data mapping technology in data integration process are used,how touse,and How to realize the data mapping using XML Technology. In addition，application ofdata mapping dictionary in geophysical prospecting professional database，and mapping ofheterogeneous data based on XML.4. Research on the application of data exchange technology.Mainly research on the effectand the application of data exchange in geophysical prospecting professional database,and theconcept of data exchange technology, Steps of data exchange, data exchange system andframework.5.Research on the specific application of data integration technology in geophysicalprospecting professional database. Mainly expounds application of data integration technologyin the geophysical prospecting professional database system.
