Answer: catalog_name.schema_name.table_name

The correct format to access or use tables in the Unity Catalog is `catalog_name.schema_name.table_name`. It's important to note that in the Unity Catalog, 'Database' and 'Schema' are terms that are used interchangeably. Additionally, a catalog is registered under a metastore. By default, every workspace comes with a default metastore named `hive_metastore`. Unity Catalog enhances this by allowing the creation of metastores that can be shared across multiple workspaces.
