In DB2, what is the purpose of user roles?
- Define table structures
- Execute SQL queries
- Manage database backups
- Simplify permission management
User roles in DB2 serve the purpose of simplifying permission management. They allow database administrators to group users with similar responsibilities and assign permissions to these roles rather than to individual users. This simplifies the management of permissions, especially in large databases with many users, by reducing the need to assign permissions individually to each user. User roles enhance security and streamline the administration process in DB2.
