Computer Reservation Systems (CRS) are backend booking systems originally designed by airlines to store and retrieve travel information. Global Distribution Systems (GDS) are worldwide networks that allow travel agents, websites, and large companies to access CRS and make reservations for flights, hotels, rental cars, and other travel items through a single point. The major GDS are Amadeus, Sabre, Galileo, and Worldspan, which are joint ventures between airlines, hotels, and rental car companies. While CRS only provide airline information, GDS allow reservations across multiple travel products.
