Abstract  

ETL needs to distinguish each kind of data, so the paper designs one kind of new data model to describe and support all data source, and analyzes the mapping relation between the data source and the goal database.Also the paper introduces the realization method about ETL core content——data source access and the data extract.

Key wordsETL      Digital library      Universal Data Model of ETL(UDME)      Mapping relation
