The drawing

What a data lineage diagram is.

A data lineage diagram traces a record from where it originates through the systems and transformations that change, store or distribute it. It makes the upstream source and downstream users of a data asset visible.

Use lineage when a team needs to understand why a value exists, where an error may have entered or which processes will be affected by a change. Label the record or dataset on each important connection.

FAQ

Common questions

What is a data lineage diagram?

It is a visual record of data's journey from source through transformations and stores to the reports, applications or people that consume it.

Why is data lineage important?

It helps teams investigate incorrect values, understand dependencies, plan changes and explain where a field or dataset came from.

What should a data lineage diagram include?

Include sources, the record or dataset that moves between steps, transformations, storage locations, destination systems and any important quality or approval checks.

How do I make a data lineage diagram?

Start with one record or dataset, identify where it is created, list each system that changes or stores it and finish with every important consumer or output.
