The objective of this experiment is to understand how database systems control and restrict access to data using different access control mechanisms.

Specifically, the experiment aims to:

• Role-Based Access Control (RBAC): To learn how to assign privileges based on user roles in order to simplify privilege management and enforce the principle of least privilege.

• Discretionary Access Control (DAC): To explore fine-grained access control using GRANT and REVOKE commands and understand how access rights can be flexibly granted and revoked in relational databases.

• Mandatory Access Control (MAC): To enforce data access restrictions based on classification levels and understand the concept of data classification and policy enforcement.
