Backward data Lineage, refers to the procedure of tracking data elements from the destination (like a report or dashboard) back to the original source. It stands in contrast to conventional data lineage, which monitors how data moves from its source to its eventual endpoint.

 

There are various use cases for employing backward data lineage:

 

1.   Understanding data point calculation: It aids in debugging errors or comprehending the rationale behind a specific report.

2.   Evaluating the alterations in data flow: If adjustments to data collection or processing are contemplated, reverse data lineage helps pinpoint all affected reports and dashboards.

3.   Regulatory compliance: Certain regulations, such as GDPR, necessitate organizations to trace the origin of personal data. Reverse data lineage facilitates meeting these obligations.
