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.
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.
The catalog source level shows how data flows from one catalog source to another with the lineage aggregating data from the data set and data element levels.
To view data lineage at the catalog source level, open a technical asset, click the Lineage tab, and then verify that the level is set to Catalog Source Level.
View classified data
When you add data classification rules to a catalog source in Metadata Command Center, the system identifies the columns and tables that match the rules and displays one or more matched data classifications on the column or table asset pages in Data Governance and Catalog.
The following image shows a column asset page with the inferred data element classifications that match the column data and metadata:
For more information about data classification assets, see Asset Details in the Data Governance and Catalog help.
View glossary associations
When you enable the glossary association capability for a catalog source in Metadata Command Center, you can view the accepted glossary assets in Data Governance and Catalog.
The Overview tab for a technical asset in the catalog source displays glossary assets in the Accepted and CLAIRE Recommendations sections.
The Glossaries panel shows the automatically accepted and CLAIRE® recommended terms.
