Unity Catalog

Unified governance for data and AI

Databricks Unity Catalog offers a unified governance layer for data and AI within the Databricks Data Intelligence Platform. With Unity Catalog, organizations can seamlessly govern their structured and unstructured data, machine learning models, notebooks, dashboards and files on any cloud or platform. Data scientists, analysts and engineers can use Unity Catalog to securely discover, access and collaborate on trusted data and AI assets, leveraging AI to boost productivity and unlock the full potential of the lakehouse architecture. This unified approach to governance accelerates data and AI initiatives while simplifying regulatory compliance.

“Unity Catalog distills permissioning into its important pieces by removing the complexity introduced by IAM policies and other data control platforms, allowing us to focus on what is important to our business use case.”

— Joseph Kesting, Software Engineer



Unified visibility into data and AI

Discover and classify structured and unstructured data, ML models, notebooks, dashboards and arbitrary files on any cloud. Consolidate, map and query data from various platforms, including MySQL, PostgreSQL, Amazon Redshift, Snowflake, Azure SQL, Azure Synapse, Google’s BigQuery in one place. Accelerate your data and AI initiatives with a single point of access for data exploration. Boost productivity by securely searching, understanding and extracting insights from your data and AI using natural language.

Single permission model for data and AI

Simplify access management with a unified interface to define access policies on data and AI assets and consistently apply and audit these policies on any cloud or data platform. Securely access data from other computing platforms using open interfaces, with consistent permissions managed in one place. Enhance security with fine-grained control on rows and columns, while efficiently managing access through low-code attribute-based access policies that scale seamlessly.

Open data sharing

Easily share data and AI assets across clouds, regions and platforms with open source Delta Sharing, natively integrated within Unity Catalog. Securely collaborate with anyone, anywhere to unlock new revenue streams and drive business value, without relying on proprietary formats, complex ETL processes or costly data replication.


“Unity Catalog allowed us to create a unified view of our data estate, simplifying collaboration across teams within BlackBerry. We now have a standard approach to manage access permissions and audit files or tables in our lake, with the ability to define fine-grained access controls on rows and columns. Automated data lineage helped us see where the data is coming from to pinpoint the source of a potential threat and to understand which research projects or teams are leveraging the data for threat detection.”

“Unity Catalog enables us to manage all users across multiple workspaces in one central place, so it makes user management significantly easier. Also, the data lineage feature is out of the box, which helps us identify the downstream dependencies without any manual overheads. In the case of BI data, we can figure out how the BI data is flowing and where the users are putting it using data lineage.”
