Data lineage is a visual representation of the flow of data across the systems in your organization. Lineage depicts how the data flows from the system of its origin to the system of its destination.
Data lineage views are available for technical assets in the catalog source. You can view
lineage at the catalog source, data set, or data element level.
The lineage at the catalog source level shows how data flows from one catalog source to
another. The lineage at the data set and the data element levels show how other technical
assets such as files or tables contribute to the selected asset.
File system assets can be source and
target endpoint objects for other catalog sources, for example Business Intelligence or ETL
sources.
File system sources don't create any references to external assets. If you
didn't assign them to any reference assets created by other catalog sources, the
Lineage
tab doesn't display the data flow.
If linking catalog sources is available for your catalog source, you can use
Metadata Command Center
to generate data lineage based on rules or by generating automated
lineage with CLAIRE. You can choose source and target catalog sources and objects to link and
generate lineage.
To determine whether linking catalog sources is available for your catalog source, navigate
to the
Configuration
tab of the
Link Catalog
Sources
page. The catalog source must appear in the list of source and target
catalog sources.
