Introduction :
This is the final report document for developed hotel
management system for Dayal hotel. It consists of the
milestones in development of finalized hotel management
system. As previously mentioned current manual system used
by hotel, caused for decrement in growth of success and
efficiency of the hotel. Iterative waterfall method was used
as the software development life cycle. Coding was handled
through an Object-oriented approach. Above mentioned
methodologies made project work load light and provided the
ease of developing. The system was evaluated by several
people regarding user levels of the developed system. Results
of the evaluation helped for further maintenance of the
product. Fully functional Dayal Hotel Management System
will fulfil the main objectives and all the events of the hotel.
Purpose :
The Software Requirements Specification (SRS) will
provide a detailed description of the requirements for
the Hotel Management System (HMS). This SRS will
allow for a complete understanding of what is to be
expected from the newly introduced system which is to
be constructed. The clear understanding of the system
and its’ functionality will allow for the correct software
to be developed for the end user and will be used for the
development of the future stages of the project. This SRS
will provide the foundation for the project. From this
SRS, the Hotel Management System can be designed,
constructed, and finally tested. This SRS will be used by
the system development team which is constructing the
HMS and the hotel end users. The Project team will use
the SRS to fully understand the expectations of this HMS
to construct the appropriate software. The hotel end

users will be able to use this SRS as a “test” to see if the
constructing team will be constructing the system to
their expectations. If it is not to their expectations the
end users can specify how it is not to their liking and the
team will change the SRS to fit the end users’ needs
Scope of the Project :
The introducing software, Hotel Management System which is
going to be implemented for Hotel Dayal will automate the
major operations of the hotel. The Reservation System is to keep
track in room and hall reservation and check availability. The
RoomManagement System is for manage all room types room
services. The Inventory Control System will keep track in all
inventories of the hotel and guest details will handled by guest
management. Administration department will monitor the all.
There is three End Users for HMS. The End Users Are Owner,
Manager and Receptionist. Owner can access to all system
functionalities without any restrictions. Manager can access to
all system functionalities with limited restrictions. Receptionist
can only access to the Reservation management section. To keep
restrictions for each End User levels HMS can create different
Login functions. The objectives of the automated Hotel
Management System is to simplify the day to day processes of
the hotel. The system will be able to handle many services to
take care of all customers in a quick manner. As a solution to
the large amount of file handling happening at the hotel, this
software will be used to overcome those drawbacks. Safety,
easiness of using and most importantly the efficiency of
information retrieval are some benefits the development team
going to present with this system. The system should be user
appropriate, easy to use, provide easy recovery of errors and
have an overall end user high subjective satisfaction.

Overall Description :
The Hotel Management System is a new self-contained software
product which will be produced by the project team in order to
overcome the problems that have occurred due to the current
manual system. The newly introduced system will provide an
easy access to the system and it will contain user friendly
functions with attractive interfaces. The system will give better
options for the problem of handling large scale of physical file
system, for the errors occurring in calculations and all the other
required tasks that has been specified by the client. The final
outcome of this project will increase the efficiency of almost all
the tasks done at the Hotel in a much convenient manner.
Product Functions :
 Make Reservations
 Search Rooms
 Add Payment
 Issue Bills
 Manage Guest (Add, Update Guest)
 Manage Room Details (Add, Update, Delete)
 Manage Staff (Add, Update, Delete, View)
 Manage Inventory (Add, Edit, Delete)

 Set Rates
 Retrieve Reports (Staff payment, Income)
 Manage Users (Add, Update, Delete)

Taking Backups
 E-mail notifications
Login interface is used to login to the system using username
and password for three different user

Adding new guest to the system
Hardware Interfaces :
Reservation alerts will be sent to the one of the member of hotel
staff as an e-mail notification. So there is a need of broadband
internet connection. Client should able to keep a stable internet
connection. A laser printer will be needed when printing bills
and several reports.

Software Interfaces :
The computer this software going to be install need to have
Windows Operating System equal or above, Windows 7. On that
Windows platform .Net 4.0 will be installed and that will be the
platform the particular software will be run. There will be an
ADO.NET data transmission with the Microsoft SQL Server
Management Studio Express 2010 R2 edition that will be
installed in the same computer.
Database Interface :
Guest
Room

Communications Interfaces :
When a specific reservation reserved at the same time an e-mail
notification will be sent to both relevant staff member’s e-mail
account and guest’s account. Guest will be notified in the check-
out date. To achieve that functionality, it requires having a
stable internet connection. Mostly a broadband connection with
the client’s computer will provide the efficient service.
Performance Requirement :
Performance requirements define acceptable response times for
system functionali ty. Although the system is developed suiting
for the least system performances, the performance of the
system will highly depend on the performance of the hardware
and software components of the installing computer. When
consider about the timing relationships of the system the load
time for user interface screens shall take no longerthan two
seconds. It makes fast access to system functions. The log in
information shall be verified within five seconds causes’
efficiency of the system. Returning query results within five
seconds makes search function more accurate.
Assumption and Dependencies :
Some software used in implementing the system is with high
cost and the client has agreed to afford the amount of money
needed to purchase them. It’s assumed that client won’t change
that decision on the next phases of the software development.
Although we assume that client is using windows 7 or windows
8. Otherwise if client use an open source operating system,
there is a need of changing the SRS accordingly.

Logical Database Requirements :
The logical database requirements include the retention of the
following data elements.
 Customer first name
 Customer last name
 Customer Code
 Customer address
 Customer phone number
 Number of occupants
 Room no
 Floor no
 Building no
 Room status
 Employee id
 Bill no
 Default room rate
 Rate description
 Guaranteed room (yes/no)
 Expected check-in date
 Actual check-in time
 Expected check-out time
 Actual check-out date

 Customer feedback
 Payment type
 Total Bill
Attributes
Reliability :
Specify the factors required to establish the required reliability
of the software system at time of delivery. Mean time between
failures and mean time to recovery.
Availability :
The system shall be available during normal hotel operating
hours.
Security :
The extent to which the Hotel Management System is safe from
outside non-allowed user or attacks.
Maintainability :
What design, coding standards must be adhered to exclusions
created

Portability :
The Hotel Management System shall run in any Microsoft
Windows environment

CONCLUSION :
Hotel management system now-a-day have the
advantage of modernization. Computer have done the
work more easy. Computer is playing a important role

in management. Reports are made on daily basis for
every customer check in or check out which can easily
be seen by the management.Hotel management
system has also primary purpose is to provide facilities
to customers. A software for computers makes the
things many times easy, these are made as user friendly
and to keep an check and balance in hotel management
and accounts as well. So ,these things are important.
