Data Transformation Debugging

All applications mentioned above, e.g., business intelligence, data integration, or data enrichment in social data management or data journalism take as input some data to be further manipulated and transformed. In many applications, including again business intelligence and data journalism, the correctness of the produced output data is crucial. It is thus important to verify the semantic correctness of a data transformation and to be able to trace back what has happened to the data within the transformation. We support this data transformation debugging based on provenance [31] , [26] .
