多源异构数据接入技术及其在垂直领域应用框架的探索OA

[Objective]The breakthrough of multi-source heterogeneous data access technology is particu-larly important for effectively solving the severe problem of"data island"in the vertical field,achieving global,authenticity,real-time guarantee of data acquisition,and data fusion applica-tions.[Methods]Through literature analysis,current researches on multi-source heterogeneous data access technologies of ETL based,semantic ontology based,robot process automation based and cloud side integration resource reflection mechanism based are summarized.The characteristics of various technologies are analyzed.[Results]Typical frameworks for the appli-cation of four multi-source heterogeneous data access technologies in the vertical field are ex-plored and designed,and four technical features are summarized and compared,in order to pro-vide valuable demonstration and reference for relevant practical applications.[Conclusions]A theoretical basis for the integration and interoperability practices of big data in the vertical field is provided,and how to fully utilize key technical methods to better solve the technical limitations of real-time da-ta access will be the focus of future research.
