Governance and Security – DE Associate Study Guide
This domain accounts for 15% of the exam and covers governing and securing data with Unity Catalog: the object model, privileges, and fine-grained access control.
Unity Catalog Object Model
Three-level namespace, broadest to most specific:
Metastore → Catalog → Schema (database) → Table/View
Objects are referenced as catalog.schema.table.
Privileges
Grant and revoke access on securable objects with SQL:
GRANT SELECT ON TABLE sales.public.orders TO `analysts`;Use GRANT/REVOKE on catalogs, schemas, and tables rather than sharing files directly.
