Lineage discovery

Due to technological limitations or security constraints, you might not always see complete lineage after metadata extraction. To build complete lineage, you can perform connection assignment from a reference catalog source connection to the endpoint objects in the reference source system. You can assign and unassign connections on the Assign Connections tab on the Lineage tab of the Configure page.

Manual connection assignment can be a time-consuming and error prone task. To simplify the task, you can use CLAIRE to build the complete lineage of a catalog source by recommending related catalog sources to assign to reference catalog source connections.

To view related catalog sources and CLAIRE recommendations, enable the lineage discovery capability when you configure a catalog source. When you run the catalog source job, Metadata Command Center assigns the reference catalog source connections to CLAIRE recommended endpoint catalog source objects. You can then view the list of CLAIRE recommendations and accept or reject them.

You can't view CLAIRE recommendations for catalog sources that don't have the lineage discovery capability. You can manually assign connections for such catalog sources on the Assign Connections tab.

For information about catalog sources that have the lineage discovery capability, see Source systems.

For more information about how to enable lineage discovery for a catalog source, see Creating a catalog source.

For relational database source systems, you can also link catalog sources and construct data lineage using the Link Catalog Sources tab on the Lineage tab of the Configure page. You can choose source and target catalog sources to link and create lineage.
