Client Orders
The system receives all incoming orders from the clients; each incoming order line specifies a product and the required quantity. Moreover, the incoming order contains information about the client, the expected delivery date and the delivery location. Finally, each order is identified by a unique ID in order to allow order tracking.
After an order is received it has to be priced: a priced order has the same structure of an incoming order but each order line also specifies the total price, which is obtained from the pricing subdomain. The priced order also specifies the total price which is obtained from the sum of the lines' prices.
After the order is priced it considered in progress, and it is the operator's job to palletize the products needed for each order. The order is considered incomplete until all the required products are palletized.
When an order is completed by the operator (i.e. all the products are taken from the stock and palletized) it is weighted; then, the operator prints the order's transport document and attach it to the pallet which is loaded onto a truck. A notification is sent to the client notifying them the order has been shipped.
