Unity Catalog provides a centralized metadata layer to enable sharing data objects such as catalogs/ schema/ tables across multiple workspaces. It introduces two new built-in admin roles (Account Admins and Metastore Admins) to manage key features.

Data discovery: Unity Catalog lets you tag and document data assets, and provides a search interface to help data consumers find data. System tables (Public Preview): Unity Catalog lets you easily access and query your account's operational data, including audit logs, billable usage, and lineage.

A catalog contains schemas (databases), and a schema contains tables and views. Note. To learn how to create a foreign catalog, a Unity Catalog object that mirrors a database in an external data system, see Create a foreign catalog. See also Manage and work with foreign catalogs.
