•Role-based access control (RBAC) is a securely best practice that designates specific persons who are authorized to view and edit particular parts of a database system.

•In RBAC, access permissions are assigned based on predefined roles or job functions within an organization.

•Here’s how RBAC works:

1.Roles: Define roles based on job responsibilities (e.g., administrator, manager, user).

2.Permissions: Assign specific permissions (read, write, execute) to each role.

3.Users: Associate users with roles.

4.Access Control: Users inherit permissions from their assigned roles.

•Benefits of RBAC:

oGranularity: Allows fine-grained control over access rights.

oScalability: Easily manage access for large user bases.

oSecurity: Reduces the risk of unauthorized access.

•Example: An employee in the HR department might have read-only access to employee records, while an administrator has full editing rights.

•RBAC ensures that only authorized individuals can access specific data or perform certain actions within the database system.
