Unity Catalog

Unity Catalog is the unified governance solution for the Databricks Lakehouse Platform, centralizing metadata, fine-grained access control (ANSI SQL), auditing, and lineage for all data and AI assets.

Unity Catalog is your command center for data and AI governance across the Databricks Lakehouse Platform. It centralizes metadata, access policies, and end-to-end lineage, allowing you to 'define once, secure everywhere' across workspaces in a region (Source 1, 7). The security model is standards-compliant, utilizing familiar ANSI SQL syntax for granting permissions, which eliminates the complexity of managing cloud IAM policies directly (Source 4, 7). You manage all assets—including tables, unstructured files (volumes), and ML models—using a clear, three-level namespace structure: `catalog.schema.table` (Source 5, 7). This provides unified control, supports open formats like Delta Lake and Apache Iceberg, and delivers automated audit logs for simplified compliance and enhanced data discovery (Source 4, 7).
