Distributed ordering scheme in order management system

摘要

An order management system includes an ordering terminal, a checkout terminal, a server, and a kitchen terminal. The ordering terminal generates and transmits order data, a seat leaving command and a seat ID, in response to user inputs. The checkout terminal is configured to process payment for the order. The server is configured to: generate an order file including an order ID based on the order data, transmit checkout data including data in the order file to the checkout terminal, in response to the order ID from the checkout terminal, transmit seat data for seat selection, in response to payment completion data associated with the order ID, transmit a cook start command in response to assignment of one or more vacant seats associated with the order ID, and update the seat data based on the seat leaving command and the seat ID received from the ordering terminal.
