A modern data dictionary
to evaluate data quality

With Atlan's auto-generated data dictionary, set up a single source of truth, build 360° data profiles and get a complete health check report on all your data.

The problem with a traditional data dictionary

A traditional data dictionary (aka metadata repository) only stores metadata. It doesn't tell you whether your data is complete, accurate or useful for further analysis. Nor does it help you understand what your data means, especially for business operations.

Enter the modern data dictionary—your go-to tool to verify data quality, detect anomalies and build transparency within data teams.

Studies show that knowledge workers waste up to 50% of time hunting for data, identifying and correcting errors, and seeking confirmatory sources for data they do not trust.
