An engineer says 'the pipeline broke here — lineage shows the ___ source.' What word fits?
In lineage, 'upstream' refers to earlier stages in the data flow — the sources that feed a broken stage. Lineage tools let engineers quickly identify which upstream source caused a failure.

What is 'lineage-based impact analysis'?
Lineage-based impact analysis uses the lineage graph to trace all downstream dependencies. Before changing a table or field, engineers can see which reports, models, or consumers would be affected.

The phrase 'tracing data from source to report' describes which lineage concept?
End-to-end lineage means being able to follow data from its original source (e.g., a transactional database) all the way through transformations to its final destination (e.g., a business report).

A colleague says 'the transformation changed the ___ of this field.' What word means the intended meaning of the data?
'Semantics' refers to the meaning of data. Transformations can change semantics without changing the field name — e.g., a 'revenue' field might change from gross to net revenue. Lineage helps detect these semantic shifts.

Which sentence correctly uses operational lineage vocabulary?
Operational lineage is used to investigate data issues — finding where NULLs, incorrect values, or unexpected changes were introduced by tracing data flow through the pipeline graph.
