Explanation:

Purpose of the Query :

The goal is to demonstrate how to create a database role and assign permissions to simplify access management.

Key Components :

CREATE ROLE: Defines a new role for grouping users.
GRANT SELECT: Assigns permissions to the role.
ALTER ROLE: Adds a user to the role.

Why Use Roles? :

Roles simplify permission management by grouping users with similar access needs.
They reduce administrative overhead and improve consistency.

Real-World Application :

Use roles to enforce security policies and streamline audits.
Regularly review role memberships and permissions.
