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.
