Abstract

Database transformations (queries, views, mappings) and the languages in which they are expressed are of obvious interest in information management. They take apart, filter and recombine source data in order to populate warehouses, views, and analysis tool inputs. As they do so, we need to track the relationship between parts and pieces of the sources and parts and pieces of the transformations’ output. This relationship is what we call database provenance.
