The Y2K Issue Essay
Delta Nervous System From 2000 through 2005 Delta started working on Delta Nervous System (DNS) a new information technology infrastructure, which cost Delta over $1.5 billion to develop. DNS intervened in the efficiency of almost every area of Delta’s operations. Connects databases that track everything from reservations and ticketing, to check-in and baggage handling, flight crew and operations. The approach used in the DNS was “publish and subscribe” approach. Whenever a certain data items change all applications subscribed to the DNS will be notified, so that employees will always have current data and information and consequently they have the ability to respond to changes as needed (Turban, Rainer & Potter, 2005). Connected through DNS, individual systems report new ticket reservation changes, and delayed flights, gate changes in real time. Software sends messages of every change occur to any system that needs it including the customers. Also any reservation ticket, for example, will be recorded in the financial systems of Delta and its boarding and flight records, among other systems.
