What is the default behavior regarding direct access to the database node in the Autonomous Data Warehouse?

The default behavior regarding direct access to the database node in the Autonomous Data Warehouse is that it is restricted. This design choice enhances security by ensuring that users cannot directly log into the database server and perform operations that could compromise the data or the integrity of the database environment.

Restricting direct access helps maintain a controlled environment where all database interactions occur through secure, managed interfaces. This means users interact with the database primarily through tools such as SQL Developer, REST APIs, or other Oracle services without needing to access the database node directly.

By implementing these restrictions, Oracle Autonomous Database is able to automate many operational tasks, provide better data protection, and simplify management tasks, thus allowing users to focus more on data analysis rather than administrative overhead.
