1.Introduction
The last thirty years mankind has experienced a tremendous evolution in the technological field. On our way to the 21st century people have achieved innumerous things and all are based on the technological evolution which is applied in every aspect of the life; Telecommunications are improved, people can contact between them literally from every point on earth. Also medicine have progressed a lot, businesses now are making transactions through computers and telephone lines while they keep huge records in a small computer etc.
Of course needless to say what impact had technological advance on the Travel and Tourism industry. Technology made travel easy and safe by creating jets, new ships as well as the advanced systems for higher safety on board. Besides that in hotels an individual can name infinite applications of technology from energy saving systems, security to communications and rooms management. Also the hotel can get closer to its potential customer much easier while reducing the cost.
Such methods are the Computerized Reservation Systems, which are going to be analyzed further at this research project. Also this project will try to make a history flashback, identify these computerized systems, describe their use, and record the advantages and disadvantages of each one. In addition it will be examined from the hotelís point of view, what sort of benefits it may have the developing and implementation of such a system. Finally it will make a report of potential technologies that will be used in the future for such systems.

2.Central Reservation Systems
Nowadays almost every lodging property and every business in the tourism industry belong to several Central Reservations Systems. There are to basic types of CRS one is the affiliate reservations network and the other is the non-affiliate reservations network. In the affiliate reservation network is a hotel chainís reservation network and all the properties are connected. Almost every hotel chain run its own reservation network or they assign the task of creating and implementing one in reservation service companies. In the affiliate reservation network properties which do not belong to the hotel chain can be part of the network and they are referred as overflow facilities (Michael L. Kasavana & Richard M. Brooks 1998, p. 145). Such properties have the advantage to be member of a large reservation network although reservations for this establishment will be made after the hotel, which owns the network will have booked all the rooms for its hotels. The advantages of having a C.R.S installed are many. First of all cost is reduced since in really advanced systems everything is automated and you do not have a large number of staff take care of the system. Besides that a hotel who has a C.R.S can be connected through a G.D.S system and have access in innumerous travel agencies or other services that could really increase the sales.
3.Global Distribution Systems
Modern hotelís central reservation systems connect to one of the global distribution systems (GDS). The largest and best known include SABRE, Galileo International, Amadeus and Worldspan. These systems are owned by airlines so SABRE is owned by American Airlines, Galileo by British Airways, KLM and SR (Ken Lord 1998, p. 53). Global distribution systems are very effective and user friendly. Through a GDS you can arrange everything from a hotel room to airfare and car rental. Here are some things that an individual can arrange through a GDS; a variety of activities at the destination, bon voyage gifts, chauffeur driven limousine, Club Med vacations, Country, State, City information, Crewed yatch charters, foreign exchange information and services, helicopter sightseeing, transfers for events, dinner/cocktail shows, cruises, gold, sightseeing programs, passports and Visas, rail schedule fares and tickets, travel insurance and travel merchandise (Ken Lord 1998, p. 53).
Through the SABRE group more than thirty thousand travel agencies, three million registered individual consumers and numerous corporation access information and book reservations with more than four hundred airlines, more than fifty car rental companies and dozens of railways, tour companies, passenger ferries and cruise line located throughout the world. Also SABRE operates one of the worldís largest privately owned real time computer systems. It links over one hundred thirty thousand terminals located in travel agencies as well as many privately owned personal computers. SABRE in 1985 introduced
