The goal of this research is to create a modern computer system, which allows to trace a parcel location at any time and inform the consignor by sending an email or SMS. The client can by himself on the Internet, set the period for receiving messages to his email or telephone. The software will send information about attempted delivery times for the parcel to the consignee and his name and adreess. The system comprises the from following subsystems – order management system, transport management system, exception reporting, track and trace, warehouse management system, data warehouse and connectivity – information backbone. The office of exchange manager needs to know if a registered bag was not received on time, without looking through information on all bags arriving. Client needs to be informed that important parcels arrived when they arrived, without having to constantly look for it via the Internet. The answer is the modern paradigm of "Alert" and wireless communication. At the basis of the system is a set of definitions of events, targets, physical units and messages – alert definition, display and messages.
