## FAQ

**What is the best data catalog software?**

The best data catalog software for large enterprises is Alation, because it combines strong search, behavioral usage signals, and governance so analysts find trusted data while stewards keep it controlled. Collibra is the best choice for heavily regulated organizations that need deep policy, glossary, and lineage at scale, and Atlan is the strongest option for modern data teams that want active metadata woven into a cloud data stack.

**Are there free or open-source data catalogs?**

Yes. OpenMetadata and DataHub are open-source catalogs you can self-host, giving discovery, lineage, and metadata management without a license fee, though you carry hosting and maintenance. The major cloud providers also include catalogs, such as AWS Glue Data Catalog, that are low cost inside their platforms. Commercial tools like Alation, Collibra, and Atlan add governance depth, connectors, and support that self-hosted options ask you to build and run yourself.

**How much does data catalog software cost?**

Enterprise pricing is quoted rather than published and scales with data sources, users, and modules. Governance-heavy platforms like Collibra, Alation, and Informatica commonly run into six figures per year for large deployments, while modern tools like Atlan, Secoda, and Select Star can start lower for focused teams. Open-source options like OpenMetadata have no license fee but carry hosting and engineering cost, so total cost depends as much on run effort as on subscription.

**What is data lineage and why does it matter?**

Data lineage maps where each dataset came from and where it flows, tracing a dashboard number back through transformations to the source table, ideally down to the column. It matters because it lets teams trust a metric, debug a broken pipeline, and see the downstream impact before changing a table. Strong lineage is a core reason organizations adopt a catalog, since without it a change to one source can silently break reports no one connected to it.
