Develop an Entity-relationship diagram for a TCS parcel delivery company which uses system-wide information for all the parcels it delivers. All parcels are identified by their tracking number and is associated with different parameters including weight, dimension, destination, delivery date, sender and receiver addresses. All items are received at various distribution centers across the country and are identified by their unique id, type and their addresses. All parcels make their way to the destination via one or more standard transportation methods (i.e. flights, delivery trucks, motorcycles, these transportation methods are characterized by their unique type, id and transportation identification number.
