Data Lineage Tracing in Data Warehousing Environments

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.
Lineage Tracing in Data Warehouses - Stanford University
http://ilpubs.stanford.edu:8090/522/
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 formally define the lineage problem, develop lineage tracing algorithms for relational views with aggregation, and propose mechanisms for performing …

Lineage Tracing in a Data Warehousing System (Demonstration Proposal) Yingwei Cui and Jennifer Widom Stanford University fcyw, [email protected] A data warehousing system collects data from multiple distributed sources and stores the integrated information as materialized views in a local data warehouse. Users then perform data analysis and mining on …

consistent lineage tracing in a multisource data warehousing environment. Our results can form the basis of a tool that allows analysts to browse warehouse data, select view tuples of interest, and then “drill-through” to examine the exact source …

Lineage Tracing for General Data Warehouse Transformations
https://www.vldb.org/conf/2001/P471.pdf
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.

Data lineage uncovers the life cycle of data—it aims to show the complete data flow, from start to finish. Data lineage is the process of understanding, recording, and visualizing data as it flows from data sources to consumption. This includes all transformations the data underwent along the way—how the data was transformed, what changed, and why.
