A trucking company is responsible for picking up shipments for warehouses of a retail chain and delivering the shipments to individual retail store locations. A truck may carry several shipments during a single trip, which is identified by a Trip#, and delivers those shipments to multiple stores. Each shipment is identified by a Shipment# and include data on shipment volume, weight, destination, etc. Trucks have different capacities for both the volumes they can hold and the weights they can carry.
