How can users and roles be created in Autonomous Database services?

Creating users and roles in Oracle Autonomous Database services can be accomplished effectively through SQL Developer. This tool provides a user-friendly graphical interface that simplifies the process of managing database objects, including user and role creation. By utilizing SQL Developer, database administrators can execute SQL commands, visually navigate schema structures, and manage permissions more intuitively compared to command-line interfaces.

While other methods may also exist for user and role creation in Autonomous Database, they might not offer the same level of ease and accessibility that SQL Developer provides. For example, the DBMS_CLOUD_ADMIN package is primarily used for managing cloud resources and is not specifically needed for creating users and roles. The Oracle Cloud Infrastructure service console focuses more on managing cloud services rather than direct database operations. SQLPlus is indeed a powerful command-line tool for database interactions but may not be as efficient for users who prefer a visual interface.

Thus, SQL Developer stands out as the preferred choice for creating users and roles due to its ability to streamline the process within an intuitive environment.
