This section describes the designs and API of this program. All API documents can be found on its GitHub Pages.

The database system has three types of users: user, securityOfficer, administrator.

• user: Users who are allowed to perform only DML operations.
• securityOfficer: Manges users and passwords. Also, they perform backup and recovery operations.
• administrator: Perform the tasks of all the above.

The AcmSubject class inherits all of the methods and fields of the AcmObject class. There are two fields that are added the AcmSubject class to differentiate it: id and role.

The AccessControlMatrix class is used to control and manage the AcmSubjects and AcmObjects.
