1. INTRODUCTION.

Information systems are now an essential part of our day to day activities. It has increased theefficiency and decrease the time for processes. When we come to a manual system if there are a large

number of processes its efficiency is very low. Lets think about a manual hotel reservation system. If there are a large number of rooms, then we will have to think for a computerized system to gain a highefficiency. Following scenario represents such a hotel reservation system which is to be converted to acomputerized system.

In order to make a computerized system, system analyst was assigned to that project and he hasgathered some information about the current manual system.

There are 100 rooms available and they are categorized into different types and each room type hasdifferent rates. The number of rooms in different types and the corresponding rates are as follows:

Room Type Room No. from/to Rate/Night

Single 1 to 60 Rs.1000Double 61 to 89 Rs.1800Suite 90 to 100 Rs.5000

A Customer can reserve a room by calling the hotel receptionist. The receptionist will answerCustomers queries regarding the room types, room rates, modes of payments available and any discounts the customer is entitled to etc. The receptionist will then take the following particulars from

The customer, if customer wishes to proceed with the reservation. Customers name. Contact address. Country. Sex. Type of accommodation. The period of stay. Expected check in date.

Subsequently the receptionist will check the room availability. If a room is available, the customer isinformed about the room availability. If customer accepts the reservation, a room number is allocated atthe same time. The customer is also informed if a room is not available. A customer can cancel the

reservation at any time. It can be done by calling or by sending a fax. The receptionist is also responsiblefor handling the cancellations. When the customer checks-in at the hotel on the reserved date, thereceptionist will obtain the customers desired mode of payment. The customer may be entitled to adiscount based on the payment mode selected.

1. METHODOLOGY.

According to the scenario we have to model the processes. Following are the methodologies

which are used to model the processes in this report. All the modeling techniques used in this reportare based on the gane & sarson methodology

2.1 Document Flow DiagramUsed to identify the physical movement of document. And from this we can see where the documents

come from where it goes to and what it is called. From this we can examine the flow of documentswithin the system.

2.2 Context DiagramShows the top level function defined to cover the scope of the application .From this diagram we can

identify all the sources and recipient data to/from the system and the major data flows to and from thesystem.
