In a warehousing environment, the data lineage problem is that of tracing warehouse data items back to the original source items from which they were derived. We formally define the lineage tracing problem in the presence of general data warehouse trans- formations, and we present algorithms for lineage tracing in this environment.

tracing problem in the presence of general data warehouse trans-formations, and we present algorithms for lineage tracing in this environment. Our tracing procedures take advantage of known structure or properties of transformations when present, but also work in the absence of such information. Our results can be used as the basis for a lineage tracing tool in a general …

This thesis presents our research results on tracing data lineage in a warehousing environment: 1. Formal definitions of data lineage for data warehouses defined as relational materialized views over relational sources, and for warehouses defined using graphs of general data transformations. 2. Algorithms for lineage tracing, again considering both relational and …

Abstract. We consider the view data lineage problem in a warehousing environment: For a given data item in a materialized warehouse view, we want to identify the set of source data items that produced the view item. We formalize the problem, and we present a lineage tracing algorithm for relational views with aggregation.
