So I am very new to creating design diagrams. I have a scenario where a user who is an admin of pizza hut selects registration option and the system prompts them to enter customer details.
Upon entering the customer details, the system creates a username and password for the customer and notifies the admin that the customer has been created and also emails the customer to let them know they are fully registered.
Now based on this, here is the UML use case diagram (on the left) and UML class diagram (on the right) I created.
Is it correct at all? If not please give some feedbacks!
