Project Computerised Hotel Management System

CHAPTER ONE INTRODUCTION 1.1

BACKGROUND TO THE STUDY

Since the emergence of electronic computer, decision making and processing of information has been very easy. Data can now be stored on computer in a considerable low space and retrieved within a short period of time compared with the manual method which is tedious and time consuming as the size of the file increases (kennedy, k, 1999). Though, the ability of computer to store, retrieve and process data can also be done by human but the major difference is that computer can reliably execute millions of instructions within a nanosecond and store the result while it takes a longer period of time for human being to execute. Hotel Management System is a software system where the management of entire hotel is computerized (KuljitKaur, Pooja1982). The application stores customer record and daily activities performed in the hotel such as customer details, reservation details, creating a new room, vacating the rooms, etc. all are computerized and the management is done without any difficulty. It also generate report for authorized user on a daily basis and weekly report, thereby reducing the time and stress that will be undergone using the manual method. 1.2

SCOPE OF THE PROJECT

The mission of this project is to facilitate easy management and administration of a hotel with capabilities to do Booking or reservations of the rooms, Cancellation of the rooms, creating of new user, Room service, Total billing etc. using the computerized hotel management software. One can keep detailed records or info on an unlimited amount of customers. The system lets the user know which all rooms are available for occupancy at any point of time. This makes the booking considerably faster. And thus helps the hotel in better management and reduce a lot of paper work as well as manpower. 1.3

OBJECTIVE OF THE PROJECT

The main objective of the entire activity is to automate and to manage the process of day to dayactivities of Hotel like: 

Room activities 1



Admission of a New Customer



Creating an account for new staff



Delete existing account



Lodge in / Lodge Out



Check room if it is currently in use



Assign properties to room according to new update of the room



Assign a room according to customer‟s demand,



Checkout of a computer and releasing the room



Finally compute the bill etc.

1.4

STATEMENT OF PROBLEM

During peak time like December period people travel a lot and lodging in Hotel cannot be over emphasized. Currently,the system of most hotels used is manual method. It requires a lot of time spared in writing the details in the paper and manually validates and maintains the records. It can involve lots of search and time wastage. Preserving and maintaining large amount of data manually is a difficult task. The manual system being is too slow, erroneous in data collection, lack of security etc. Finding out the final payment amount completely relies on the hotel manager and if he is absent, it takes a long time to find out the details during check out and is prone to errors. Drawbacks of the Manual Method 

Manual entry consumes more time.



It is difficult to maintain bulk of record in manual.



Restrictions in the users.



Not easy to prepare the daily reports.



Lack of accuracy and error prone.



Overall efficiency is less.



Lot of paperwork.



Non-secure.



No perfect maintenance of report. 2

No method to trace details



Human errors



The manual system is too slow



Searching is more time consuming

1.5



SIGNIFICANCE OF THE STUDY

The proposed system is to facilitate easy management and administration of a hotel with capabilities to do Booking or reservations of the rooms, Cancellation of the rooms, Cash billing, ordering of food, Adding new staff, Generate bill, Review of report, etc. using the computerized hotel management software. 1.6.

CHAPTER TWO LITERATURE REVIEW 2.1

HISTORICAL BACKGROUND STUDY

The hotel proprietors Act, 1956, a hotel is an “Establishment held out by the proprietor as offering food, drink and if so required, sleeping accommodation, without special contract to any traveller presenting himself who appears able and willing to pay a reasonable sum for the services and facilities provided and who is in a fit state to be received” (KuljitKaur, Pooja, 1982). Hotel is a place where all who conduct themselves properly, and who being able to pay and ready to pay for their entertainment, are received, if there be accommodation for them, who without any stipulated engagement as to the duration of their stay or as to the compensation, are while there, supplied at reasonable cause with their meals, lodging and other services and attention as are necessarily incident to the use as a temporary home‟(KuljitKaur, Pooja, 1982). Hotel keeping can be traced back to many centuries and its evolution through the ages has been brought about by Britain‟s economy and industrial changes and developments. During the seventh and eight centuries, it was the monasteries that supplied hospitality to strangers and, as no charge was made for the accommodation; all travelers were expected to contribute according to their means to the abbey funds(KuljitKaur, Pooja, 1982). As more people began to travel there group themselves together, not only for the company, but for mutual protection from highway men and robbers. Consequently, travelers arrived in groups at a monastery and it was often difficult to accommodate them all. In the early nineteenth century the concept of a hotel room in the bedroom, and this period is known as “Golden age of hotel of the great Britain and the world”. Hotel proprietors were legally referred to as „Common Innkeepers‟ (George Koch, 1998). The turn of the century saw an era that was called „Belle Epoch‟ when grand and luxurious hotel flourished. A few hotels are still operating today. In London and some other cities attempts have

4

been made to recapture some of the grandeur of the past Vera in the making of the modern hotels, and bring back the memories the grand hotels and old days (George Koch, 1998). According to my research on this project it was discovered that the term „Hotel‟ was used in England in about 1760. Hotel or inn is defined by British law as a place where travelers can receive food and shelter, provided he is in a position to pay for and is in a fit condition to be received‟(George Koch, 1998). 2.2 MANAGEMENT INFORMATION SYSTEM A management information system (MIS) is a system that provides information needed to manage organizations effectively. Management information systems are regarded to be a subset of the overall internal controls procedures in a business, which cover the application of people, documents, technologies, and procedures used by management accountants to solve business problems such as costing a product, service or a business-wide strategy. Management information systems are distinct from regular information systems in that they are used to analyze other information systems applied in operational activities in the organization. Academically, the term is commonly used to refer to the group of information management methods tied to the automation or support of human decision making, e.g. Decision Support Systems, Expert systems, and Executive information systems 2.3

RELATED WORKS

A student information system (SIS) is a software application for educational establishments to manage student data. Student information systems provide capabilities for entering student test and other assessment scores through an electronic grade book, building student schedules, tracking student attendance, and managing many other student-related data needs in a school, college or university. The Student Information System also known as student information management system (SIMS,SIM), student records system (SRS), student management system (SMS), and campus management system (CMS) or school management system (SMS). The SIS is equivalent to an Enterprise Resource Planning or ERP system for acorporate customer. As such, many of the issues with ERP System Selection Methodology, implementation, and operation of an ERP system apply to schools and their SIS systems. These 5

systems vary in size, scope and capability, from packages that are implemented in relatively small organizations to cover student records alone, to enterprise-wide solutions that aim to cover most aspects of running large multi-campus organizations with significant local responsibility. Many systems can be scaled to different levels of functionality by purchasing add-on "modules" and can typically be configured by their home institutions to meet local needs. Until recently, the common functions of a student records system are to support the maintenance of personal and study information relating to:  Handling inquiries from prospective students  Handling the admissions process  Enrolling new students and storing teaching option choices  Automatically creating class & teacher schedules  Handling records of examinations, assessments, marks and grades and academic progression  Maintaining records of absences and attendance  Recording communications with students  Maintaining discipline records  Providing statistical reports  Maintenance boarding house details  Communicating student details to parents through a parent portal  Special Education / Individual Education Plan (IEP) services  Human resources services  Accounting and budgeting services  Student health records In larger enterprise solutions that have student data at their core, further functions include Student financial aid management and more may be customized by the developer. Where national or government systems exist for student finance or statistical return purposes, student records system often provide functionality that caters for this, by way of modules or coreelements that handle the production of required files, or deal with the formatted transfer of information. Examples are the FAFSA (Free Application for Federal Student Aid) process in the United States, the United Kingdom's Student Loans Company processes (SSAR, 6

SSAC and ATFEE file processing), the UCAS (Universities and Colleges Admissions Service) in the United Kingdom, or the HESA and HESES student statistical returns in the United Kingdom. In the past, universities and large school districts in particular have created their own bespoke student record systems. One such example is the ROSI system at University of Toronto. With growing complexity in the business of educational establishments, most organizations now choose to buy customizable software, and increasing numbers are buying software as a service (SAAS) such as QuickSchools.com, Orbund, EMPOWER, WeBSIS, Spiral Universe, and Renweb. Most student information systems in use today are server-based, with the application residing on a central computer server, and being accessed by client applications at various places within and even outside the school. But student information systems have been moving to the web since the late 1990s and that trend is accelerating as institutions replace older systems. 2.4

INTEGRATED SYSTEMS / HOSTED SERVICE

In recent years, several forces have been driving an evolution of student information systems and as a result, leading many institutions to replace theirs. Those forces are:  Demand for 24x7 web-based access to information by students, instructors, and (in primary and secondary education, or K-12) parents  Increasing demands in the amount and frequency of data reporting for accountability and other purposes (so-called "vertical reporting" up to state, provincial, and national agencies)  Importance of integrating student information systems with other tools, especially relating to instruction (IMS systems like Orbund, Maestro, School Net and School City in the US), courses (CMS systems like Blackboard, RM Learning Platform, Chamilo, Claroline, eFront, elearnapp, Dokeos, Sakai, Moodle, Spiral Universe) and learning (LMS systems and on-line course ware like APEX).

2.5

UPGRADE PITFALLS

Unlike an upgrade to a web browser or a word processor, changes and upgrades to these systems tend to have significant impact on the day-to-day operations of every school employee. These systems typically touch every aspect of school operations even when only the base modules are used. For these reasons, care should be taken to consider the impact on:  Workflow: Since these programs are tightly tied to a school's business workflow and processes, a change to a SIS system can force changes to workflow. This can have a significant impact on daily operations if not considered carefully prior to implementation.  Data Conversion: Data conversion of historic data (transcripts, attendance, health records, etc.) for both current and past students can also be a significant issue to transitioning to a new SIS. Since most schools are required to keep historical data on past students, considerations should be given to what information will be converted and what will be archived.  Customized Reports: Since there is little standardization in what and how student information is stored, most schools have their own processes and procedures (e.g. formatting and layout of data reports) for student grade printouts or attendance records. As most SISs are not perfectly compatible with the previous SIS, upgrading can be a long and tedious process.  Training: Some new SIS programs have a tendency to include some unnecessary features, primary for the use of power users, so training employees to use the new SIS program will most likely be a costly and time-consuming process. Like with an ERP system, schools should consider processes similar to the ERP System Selection Methodology when selecting a SIS system. 2.6

CHAPTER THREE DESIGN METHODOLOGY 3.1

ADOPTED METHODOLOGY

The methodology used for this project is Rapid Application Development (RAD). Rapid Application Development (RAD) refers to a type of software development methodology that uses minimal planning in favor of rapid prototyping. The "planning" of software developed using RAD is interleaved with writing the software itself. The lack of extensive pre-planning generally allows software to be written much faster, and makes it easier to change requirements. 3.2

SYSTEM DEVELOPMENT MODEL

The Model to be employed in the development of this system is the Rapid Application Development model. This is an adaptation of the traditional Waterfall model and is better suited for this project because the development steps can be carried out concurrently i.e. While more data is been gathered to make the system robust and fully effective, design and coding can start and additions made as the project moves on. This will also make room for early testing to ensure that the system meets its requirement. The steps involved in Rapid Application Development are:  Planning and Document Requirements  System Analysis and Design  System Development  Testing  User Review 3.3

THE PLANNING PHASE

The goal of the planning phase is to map broad capabilities of the system from the student perspective. The phase is further divided into the following sub-phase:  Project Definition  Session 10

 Final Document 3.3.1 Project definition This has to do with identifying what the management wants from the project. These include the Purpose, Scope, Objectives, Business Process, Constraints, Resources Requirements, Assumptions and Open issues. The purpose of this particular project is to provide a platform that allows customer and staffs to automate their work in the hotel by keeping information about customer and staffs in the database and generate daily or weekly report for management decision making. 3.3.2 Session This stage defines how information is entered into the system via computer screen. The two type of defining screens are screen flow and screen design. The session also includes the definition of all outputs from the system and any other printouts. 3.3.3 Final document The final document contains the entire documentation of the project meetings, procedures and other relevant documents needed for the successful execution of the project. 3.4

DESIGN PHASE

The design phase is divided into two tiers; the front-end and the back-end. The front-end is a graphical interface developed using VB.NET and the back-end which is the database was developed with Microsoft SQL Server. 3.5

DATABASE DESIGN

As earlier stated, the database was built using Microsoft SQL Server 2005 and it consists of various tables storing varying information. The description of each table is stated below. 1.

BILL TABLE:It contain information about charges of customer such as food variety charges, room bill, service tax, and extra charges.

11

2.

CHECK TABLE: This contain information about check-in time of customer and checkout time of customer, this table also keep record of number of days spent in the hotel.

3.

CUSTOMERS TABLE:This contains record of customers such as customer id, customer name, customer address, and phone number.

4.

LOGIN TABLE:It contains the login information and the information about authenticated user of the system, such as user name, password, first name, last name, phone number.

5.

RESERVATION TABLE:It contains information about customers who reserved for later use. Information stored in this table include reservation id, reservation name, address, phone number, reservation date, and no of days used to reserve the room.

6.

ROOM_MASTER TABLE: Data stored in this table includes room number, room type, status of the room, and tariff charge of the room.

7.

VARIETY TABLE:This table keeps the record of different variety bought in the hotel such as food variety and the full details of the variety such as variety id, variety name, customer id of the customer that bought the variety, costs of the variety.

3.6

APPLICATION ACTIVITY

The application activity illustrates the flow of activities that needed for the operation of the proposed system. In other words, application activity shows how the program is started till when the program is terminated. i.

The process begins; the splash screen is displayed that contain the picture and logo of the hotel welcoming the user “welcome to Daktad Hotel& Suite Hotel Management System” then the system automatically proceed to login page. The user logs in either as an administrator or staff.

ii.

If the user is an administrator, he can add a new staff according to their designation, review daily transaction, daily report, weekly report and monthly report, mobilized report for printing, edit or delete staff account.

12

iii.

If user is a staff he/she can make use of interface like the input customer information, view room status, order for food according to customer request, assign room for customer, generate receipt for customer after lodge-out and

iv.

The administrator can access any page in the Admin modules

v.

The user signs out.

vi.

The process ends

3.7

INPUT DESIGN

The input requirement of the design phase includes the following: Admin username: This is the required username for administrator to enter in the application Admin password: This is the password of an administrator Staff username: This is the users‟ username Staff password: This is the users‟ password 3.8

PROCESS DESIGN

1.

Room Enquiry and Reservation Module

This module deals with reservation enquiry and reservation. During reservation, the details of the customers, type of room required and number of room required are fed in to the system. Once these in formations are entered, the system searches for the unoccupied rooms and displays the result. In reservation enquiry, customer can get the information such as rent of rooms and details of rooms available. 2.

Check In/Check-out Module

This module deals with the reservation checkin (i.e., allocating room for the customer who has already reserved) Direct checkin (i.e., checking in without reservation), handling checkout of guest and Bill payment. 3.

Bills and Payments Module

13

This module deals with the generation and tracking of bills and payments made by the guest. The bills are classified into lodging bills and Restaurant Bill. The lodging bill is calculated using the check in and checkout details of the person. The Restaurant bill is generated based on the food items consumed by the guest during his stay in the hotel. 4.

Reports

This module deals with the generation of the reports for the various modules. The customer list can be generated. Room status list can be retrieved for reference. The check in and check out registers can also be retrieved for any future queries. 3.9

OUTPUT DESIGN

The requirement of the output design phase is: Report of Hotel Management System

3.10

SYSTEM DEVELOPMENT

Software development like any other field requires a prompt and proper planning in order to have stable and reliable foundation for further development. 3.11

TESTING

This phase test the system before proper deployment to check for errors in its design, where the code modules produced are tested to unravel bugs and ensure that they conform to the stated Users‟ Requirements. The type of system test used during the development of this application is “UNIT TEST”. This test ensures that each unique path of this project performs accurately to the documented specifications contains clearly defined inputs and expected results. 3.12

DATA FLOW DIAGRAM

The data flow diagram (DFD) is one of the most important tools used by system analysts. Data flow diagrams are made up of a number symbols, which represent system components. Most data

14

flow modeling methods use four kinds of symbols. These symbols are used to represent four kinds of system components such as Processes, data stores, data flows and external entities. Circles in DFD represent processes. Data Flow is represented by a thin line in the DFD and each data store has a unique name and rectangle represents external entities. Unlike detailed flow chart, Data Flow Diagrams do not supply detailed description of the modules but graphically describes a system‟s data and how the data interact with the system. An arrow identifies the data flow in motion. It is a pipeline through which information is flown like the rectangle in the flowchart. A circle stands for process that converts data into information. An open-ended box represents a data store, data at rest or a temporary repository of data. A square defines a source or destination of system data.

CHAPTER FOUR SYSTEM IMPLEMENTATION AND EVALUATION 4.0

SYSTEM IMPLEMENTATION

This chapter deals with the implementation and evaluation of the designed system for verification and validation of the various program/function modules embedded in the design. It introduces the software and hardware requirements for the system to work properly. 4.1

CHOICE OF PROGRAMMING LANGUAGE AND TOOLS

The programming language used for this application is Microsoft Visual Basic.Net. Visual Basic (VB) is a programming language based on the original DOS language called BASIC (Beginners' All-purpose Symbolic Instruction Code). VB.NET 2010, an offshoot of Visual Basic, is an object-oriented programming language based on VB that is implemented using the Microsoft .NET framework. Visual Basic .NET can be used to create win forms or web applications and create programming based in any object-oriented programming language (OOP), ADO.NET, Multithreading or Windows Services. VB.NET programming utilizes concepts connected to string encryption, forms inheritance, regular expressions and deployment. During the course of using this approach, the following techniques were adopted: The Top-down design approach the development process begins with the most general view of the application and progressively moves towards a more detailed view. The top-down philosophy ensures that testing of each of the modules begins as soon as they are developed without necessarily completing the project. 4.2

SOFTWARE REQUIREMENTS

The software requirements for this application include:  Windows XP, Windows Vista and Windows 7  Microsoft SQL server  Microsoft.Net Framework  Anti-virus software to prevent unwanted attack to the system  Firewall software to prevent malicious user attack to the system

18

4.3

HARDWARE REQUIREMENTS

The hardware requirements for this software to run are:  Processor Intel Pentium class 833MHz or higher  RAM 256Mb or higher  60Gb Hard-Disk or higher(recommended)  VGA 800X600, 256 colour  Laser Jet Printer  Uninterrupted Power Supply (UPS) 4.4
