A Reverse-Based Method of Tracing Data Provenance in ETL
Data integration may have no meaning without data provenance, and ETL is an important step of data integration, so to trace the provenance of ETL process is significant for data integration. A method based on inverse functions is described in this paper. At first, the ETL process is divided into three layers, Then we analyzed each layer and designed the inverse mechanism, and described the algorithms of provenance tracing based on this. At last, we take an instance to show the result.
