What Data Lineage Reveals
Data Lineage tells you which data sources, tables, and columns provided the data found in a specific resource. This information can help you understand:
• What will be affected by a proposed change to a column or resource.
• How a published resource is provided to a consuming application, so that you can trace dependencies back to their origins.
• What resources you might need to have privileges for, because of resource dependencies.
For further details on how TDV collects and displays data lineage information, see the TDV User Guide.
