Data Provenance for Attributes: Attribute Lineage.

Abstract

In this paper we define a new kind of data provenance for database management systems, called attribute lineage for SPJRU queries, building on previous works on data provenance for tuples. We take inspiration from the classical lineage, metadata that enables users to discover which tuples in the input are used to produce a tuple in the output. Attribute lineage is instead defined as the set of all cells in the input database that are used by the query to produce one cell in the output. It is shown that attribute lineage is more informative than simple lineage and we discuss potential new applications for this new metadata.
