The UML class diagram for a cafe management system shows key elements. It includes customers, orders, menu items, employees, and payment processes.

The core of the system is the order class that defines an order made by a customer. The order class has these features: order ID, total price, status, and a set of menu item objects. Customers have the functionality to place orders, change order status, cancel orders, and prepare bills.

The customer class embodies people going to the cafe. It includes features like customer ID, name, and contact info. It also stores past orders in a list called order history. The menu item class represents cafe products. It includes the item ID, name, price, category, and a list of ingredients. Menu items are capable of being added, changed, or deleted in the system.

The payment class manages order-related financial transactions. It has properties such as payment ID, amount, method, and status. These link each payment to an order. Payments can be processed and refunded accordingly.
