GRANT and REVOKE

GRANT and REVOKE are SQL commands used to manage user permissions in a database. GRANT is used to give specific privileges (such as SELECT, INSERT, UPDATE, DELETE) on database objects to users or roles, while REVOKE is used to remove these privileges. These commands are essential for implementing database security, controlling access to sensitive data, and ensuring that users have appropriate permissions for their roles. By using GRANT and REVOKE, database administrators can fine-tune access control, adhering to the principle of least privilege in database management.
