Data Lineage
Also written as Data Provenance, Column-Level Lineage
A traceable map of where each number in a report came from — which source, through which transformations.
Think of it like
The paper trail on an ingredient, from the farm to the plate.
Junior or senior?
Comes up the day an executive dashboard shows a wrong figure and nobody can say why.
Senior sounds like
Has been the person who traced it back.
Ask them
“A number in a dashboard looked wrong. Walk me through how you found where it came from.”
