What they do differently
Lineage explains dependencies and impact. A catalog helps people discover, understand, and trust assets. In practice many products combine both, but the buying lens should start from the operational problem that is most painful right now.
When each matters more
If incidents, broken dependencies, and change impact dominate, lineage matters more. If the main problem is findability, ownership, and documentation, a catalog often becomes the better first investment.
Comparison snapshot
| Dimension | Data Lineage | Data Catalog |
|---|---|---|
| Primary job | Impact and dependency visibility | Discovery and trust context |
| Best fit | Teams solving incident and change risk | Teams solving findability and understanding |
| Tradeoff | May not solve documentation alone | May not solve dependency analysis deeply enough |
