Class diagram

Class diagram
Create a class diagram created from a sequence diagram to cancel an order.
Next, create an abstract Profile class that has the abstract methods to display, edit, and save and the AddDate attribute.
Next, create specific carrier profile, seller profile, manufacturer profile, and employee profile classes.
These particular classes will contain their own methods and attributes as well as the methods and attributes they have inherited. These inherited methods, as well as their own methods, are called specific methods (similarly to attributes). Specific classes are linked to an abstract class by generalization.
