Data center underlying data accumulation usually use three kinds of means,which are ETL technology,Data Federation technology,Middleware technology.But the three technology focuses on different,which can't satisfy the data integration and persistence of usability at the same time.Combining with technical advantage virtual data integration is put forward.In order to solve the data of heterogeneous data model of data virtual between the conversion of data,according to analyze the data virtual,a kind of data virtual architecture for data transforming is proposed which merges technique of metadata-driven.A series of supporting metadata models are built to describe and store plocies of mapping pattern in details,meanwhile the corresponding data routing strategies are built.For reducing the processing impedance,the equivalence primary key ideas is put forward.
