Abstract

Data lineage tracing (DLT) is to find derivations of integrated data in integrated database systems, where the data sources might be autonomous, distributed and heterogeneous. In previous work, we present a DLT approach using partial schema transformation pathways. In this paper, we extend our DLT approach to using full schema transformation pathways and discuss the problem of lineage data ambiguities. Our DLT approach is not limited in one specific data model and query language, and would be useful in general data warehousing environments.
