Lineage¶

Lineage shows how data flows from its origins to its various destinations. This includes details of the processing along the way. It is used to understand:

• whether the data used in reports and analytics models has come from the correct sources and has passed through the correct processing (known as traceability of data).

• what would be the impact on downstream processing and consumers if something was changed (known as impact analysis).

• whether the operational processes that implement the data flows are executing correctly (known as governance by expectation).

Lineage Management describes how lineage is collected, managed and used in Egeria.
