An online ordering system is a system that is put in place to allow restaurants and cafes to take orders and accept payments from a distance - both online and in-person. With this system, customers simply access an online menu. As represented below, an online product ordering system will have multiple entities, like Customer (Name, Username, ID), Customer's Information (Address, Contact Number, Email Address, Postal Code), Order (ID Number), Employee (Name, Age, Address, ID Number, Field of Work), Product (Availability of Products, Price Per Item, Quantity, Name, ID, Description), Product Category (Name, Description, Photos), and Manufacturer (Company Name, Contact Information). Use EdrawMax Online to create a similar-looking ordering system for your project.
