Unity Catalog securables are objects defined in the Unity Catalog metastore on which privileges can be granted to a principal (user, service principal, or group). These securable objects are hierarchical and include:
Metastore: The top-level container for metadata.
Catalog: The first layer of the object hierarchy, used to organize data assets.
Schema: Also known as databases, schemas contain tables and views.
Table: The lowest level in the object hierarchy, tables can be external or managed.
View: A read-only object created from a query on one or more tables.
Materialized View: An object created from a query on one or more tables, reflecting the state of data when last refreshed.
Volume: Can be external or managed, used for storing data.
Function: A user-defined function or an MLflow registered model.
Model: An MLflow registered model, listed separately from other functions in Catalog Explorer.
These securable objects allow for granular control over data access and management within the Unity Catalog
