Question

Draw a UML class diagram for an employee salary management system. Define all classes, attributes and operations of each class. Employees work progress will be recorded and compared to projected progress and promotions will be determined through this.

I HAVE THE FOLLOWING CLASSES: (add or subtract as needed)-

user class, role class, department class, salary class, employee class, payment or payroll class, performance class and permission class.

Any addition or subtraction to this list of classes ?

Please help me. Thanks
