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.
