A SYSTEM FOR ROOM BOOKING IN LAX HOTEL:
The project addresses the information required by LAX hotel to book rooms and clears the bills of
customers. The hotel has decided to computerize room booking and customer checkout formalities.
The hotel has various types of rooms. It wants to allow booking online through the internet besides
normal booking by phone, letter and also spot booking on arrival of the customer. The hotel
management is willing to invest in a PC with internet connection. It is also willing to train the staff
at the reception desk to handle computerized booking. It is unwilling to invest in a local network
in the hotel, which would allow on-line updating of customer charges. Customer bills are sent from
restaurant, laundry etc to the reception desk accountant for manual updating of accounts. Since the
hotel is small with only 177 rooms, this is feasible.
