FedEx prides itself on having up-to-date information on the processing and current location of each shipped item. To do this, FedEx relies on a company-wide information system. Shipped items are the heart of the FedEx product tracking information system. Shipped items can be characterized by item number (unique), weight, dimensions, insurance amount, destination, and final delivery date. Shipped items are received into the FedEx system at a single retail center.

Retail centers are characterized by their type, uniqueID, and address. Shipped items make their way to their destination via one or more standard FedEx transportation events (i. e., flights, truck deliveries). These transportation events are characterized by a unique scheduleNumber, a type (e. g., flight, truck), and a deliveryRoute.
