According to current computer application development, computer management system is changing from early C/S pattern to B/S pattern, and partly enters the trend direction of small client and big server. Therefore, developing of management system for medium and small hotels suits such situation. And this development wil l make a basis for the future s development of multi-clients and multi-data-swap.Developing B/S management system for medium and small hotels is realistic needs of those hotels.Early developed C/S system is widely used by medium and small hotels.
