- Design a class diagram for the following project description online retailer system The system will deal with a number of domain entities – including items, orders, and customers. The items that we sell fall into user-defined categories. Some categories, such as liquor, are flagged as being restricted – customers under the age of 18 are not allowed to buy restricted items, and the system should raise an exception if they attempt to. In addition, we have to maintain certain details on all items – such as the item name, description, price, and category The system also need to maintain customer information – including names, email addresses, and age. Each customer has to have an address, to be used for billing and delivery. Customers can change their details whenever they want When a customer places an order, the system will calculate a delivery fee by using delivery priority and distance from warehouse. Orders of more than $100 qualify for free delivery, at normal priority. Overnight…___ is the process of communicating with items using well-defined interfaces, but not being permitted to know how other objects are implemented.If you are a developer rather than a user, you should utilise deep access rather than shallow access. Shallow access is preferable for users.
