Data lineage is the process of tracking data as it is moved and used by different software tools. Use Manta Data Lineage to increases data pipeline transparency so you can determine data accuracy throughout the models and systems.
- Required services
- IBM Knowledge Catalog with IBM Manta Data Lineage service enabled. For more information how to enable data lineage, see Enable data lineage.

- You can track your data and learn where it came from, how it was transformed, and where the data was moved.
- You can check your data in one view for quality scores or transformations.
Before you start using Manta Data Lineage, you need to perform additional tasks to prepare your data. See Preparing data for data lineage.
