1.1 GeneralThis is a Project work undertaken in context of partial fulfillment of BCA.I have tried my best to make thecomplicated process of Hotel Management System as simple as possible using Structured & Modular technique & Menu oriented interface. I have tried to design the software in such a way that user may nothave any difficulty in using this package & further expansion is possible without much effort. Even though Icannot claim

That this work to be entirely exhaustive, the main purpose of my exercise is perform each employeesactivity in computerized way rather than manually which is time consuming.

I am confident that this software package can be readily used by non-programming

Personal avoiding human handled chance of error. This project is used by only admin

User

i. Administrator

Administrator can maintain daily updates in the hotel records. Administrator is must be an authorized user.

The main aim of the entire activity is to automate the process of day to day activities of hotel like Roomactivities, Admission of a New Customer, Assign a room according to customers demand, checkout of acomputer and releasing the room and finally compute the bill etc.

The limited time and resources have restricted us to incorporate, in this project, only main activities that areperformed in a HOTEL Management System, but utmost care has been taken to make the system efficientand user friendly. HOTE Management System has been designed to computerize the following functionsthat are performed by the system:

Room Detail FunctionsOpening a New RoomModification to room assignedCheck-in and check-out Detail Functions

1.2 Project ObjectiveDuring the past several decades personnel function has been transformed from a relatively obscure recordkeeping staff too central and top level management function.There are many factors that have influenced this transformation like technological advances,professionalism, and general recognition of human beings as most importantResources. A computer based management system is designed to handle all the primary information required to

calculate monthly statements. Separate database is maintained to handle all the details required for thecorrect statement calculation and generation. This project intends to introduce more user friendliness in the various activities such as record updating,maintenance, and searching. The searching of record has been made quite simple as all the details of the customer can be obtained bysimply keying in the identification of that customer. Similarly, record maintenance and updating can also be accomplished by using the identification of thecustomer with all the details being automatically generated. These details are also being promptlyautomatically updated in the master file thus keeping the record absolutely up-to-date. The entire information has maintained in the database or Files and whoever wants to retrieve cantretrieve, only authorization user can retrieve the necessary information which can be easily be accessiblefrom the file. The main objective of the entire activity is to automate the process of day to day activities of Hotel like:

1.Room activities,2.Admission of a New Customer,3.Assign a room according to customers demand,4.Checkout of a computer and releasing the room5.Finally compute the bill etc.6.Packages available.7.List of Regular customers.

1.3 Problem Specification/Need of ProjectI have designed the given proposed system in the C#.NET to automate the process of Hotels.This project is useful for the authorities who keep track of all the users registered in a particular state .Theauthority can add hotel packages, room details, availability of rooms, booking etc.

The following steps that give the detailed information of the need of proposed system are:

Performance : During past several decades, the records are supposed to be manually handled for allactivities. The manual handling of the record is time consuming and highly prone to error. To improve theperformance of the Hotel Management System, the computerized system is to be undertaken. This projectis fully computerized and user friendly even that any of the members can see the report and status of thecompany.

Efficiency: The basic need of this software is efficiency. The software should be efficient so thatwhenever an Admin submits the details of the customer the Database is updated automatically.This record will be useful for other users instantly.

Control: The complete control of the project is under the hands of authorized person who has thepassword to access this project and illegal access is not supposed to deal with. All the control is under theadministrator and the other members have the rights to just see the records not to change any transactionor entry.

Security : Security is the main criteria for the proposed system. Since illegal access may corrupt thedatabase. So security has to be given in this project.

. Software Requirement Specifications3.1 Introduction

Software Requirement Specification (SRS) document usually contains a software vendorsunderstanding of a customers software requirements. This document ensures that the software vendor andthe customer are in agreement as to the features required in the software system being built. SRS is createdafter the initial requirement elicitation phase in which Software vendor interacts with the customer to


10/28

understand the software needs. Usually SRS documentation is prepared by a business analyst who has sometechnical background.

An SRS is written in precise, clear and plain language so that it can be reviewed by a business analystor customer representative with minimal technical expertise. However it also contains analytical models (usecase diagrams, entity relationship diagrams, data dictionary etc.) which can be used for the detailed designand the development of the software system. SRS is one of the most critical pieces of software development

since it acts as the bridge betweens the software developers and business analysts. An incomplete orincorrect SRS can have disastrous effects on a software project.

3.2 Description of methods in terms of development flowThe process of identifying, modeling and documenting how data moves around an

information system. Data Flow Modeling examines processes (activities that transform data fromone form to another), data stores (the holding areas for data), external entities (what sends data intoa system or receives data from a system, and data flows (routes by which data can flow).

3.3 Description of Project flow (layer wise)

3.4 Description of software models why this modelhas been opted for the purpose of development. The basic objective of HOTEL MANAGEMENT SYSTEM is to generalize and

simplify the monthly or day to day activities of Hotel like Room activities, Check in of New Customer, Check out of customer, assigning a room according to customerrequirement, and finally compute the bill etc. which has to be performed repeatedly onregular basis. To provide efficient, fast, reliable and user-friendly system is the basicmotto behind this exercise.Let us now discuss how different functions handle the structure and data files:1 Password

In this module, this website is for multiple users. If a User enters a passwordand the software checks its validity. If the password is valid then option is given tochange the password, otherwise Invalid User/Password message is displayed. Thereis an option for password recovery, log out, login, new users sign in. The Administratorcan also update changes in the site after login.2 Creating new Entity (Hotel, Room, Customers, Members etc.)

This is used to add a new employee details, delete entity details and view thedetails. In that screen, the automatic item is created.In this function, whenever a new entity is required to be added the correspondingforms are opened and the database is manipulated to check whether the data isalready existing or not. If it already exists, then it prompts that Entry already existingand if not than the data is entered with the various validation checks.3. Function NEW_ROOM ()

This is the function used to open a new room for a customer so that he/she canassign a separate room. In that screen, the automatic room number is created.


11/28

After opening a new room for the customer, finally a room is assigned to a customerand the room records are appended in the data file.4. Function CHECKIN_CUSTOMER ()

This function is used to admit a customer in our Hotel after entering his allpersonal details like Name, Address, Phone, Sex and then he/she is assigned a roomfrom NEW_ROOM() function.

5. Function CHECKOUT_CUSTOMER () This function is used to checkout the customer details from database. When theuser inputs his room number, the same room number will be checked in the database,if the room number is matched in the database, then the customer will be check-outfrom the database and transferred the record of the checkout to another table of database so that the Hotel Management has the record of customers who have check-out to fulfill his legal liabilities.6. Function GENERATE_BILL ()

When any customer check-out, his/her bill is generated automatically bycalculated check-out date minus check-in date and getting multiplied it by daily roomcharge plus other charges and the bill has to be saved in the table in the database.7. Function DISPLAY_RECORD ()

This function is used to display all the transaction including the customer name,address, phone, bed number, and doctor assigned to him/her in the screen. This is aglobal report to display all the transaction records in the screen.8 Validations of Data Entered by the User & Error Handling

In this function, the validity of data entered by the user during the variousbusiness processes is checked through various validation checks. For example, thereshould not be any characters entered in the numeric fields, likewise if there is any erroroccurs than it should handle that particular error and give the required messages.9 Searching

In this function, room, customer well as members can search details from thedatabase according to their authentications

4. Design4.1 Introduction

Entity

Relationship Diagram: This depicts relationship between data objects.The attribute of each data objects noted in the entity- relationship diagram can be described using adata object description. Data flow diagram serves two purposes:

1. To provide an indication of how data are transformed as they move through the system.

2. To depict the functions that transformation the data flow.

Data Objects :A data object is a representation of almost any composite information that must be

understood by the software. By composite information, we mean something that has a number of

different properties or attributes. A data object encapsulates data only there is no referencewithin a data object to operations that act on the data.

Attributes:Attributes define the properties of a data object and take on one of three different

characteristics. They can be used to:Name an instance of data object.Describe the instance.Make reference to another instance in other table.

Relationships : Data objects are connected to one another in a variety of different ways. We can define a

set of object relationship pairs that define the relevant relationships.

8 Validations of Data Entered by the User & Error Handling

In this function, the validity of data entered by the user during the various businessprocesses is checked through various validation checks. For example, there should not beany characters entered in the numeric fields, likewise if there is any error occurs than itshould handle that particular error and give the required messages.9 Searching

In this function, room, customer well as members can search details from the databaseaccording to their authentications.

DatabaseThe general theme behind a database is to handle information as an integrated whole.

A database is a collection of interrelated data stored with minimum redundancy to serve manyusers quickly and effectively. After designing input and output, the analyst must concentrate ondatabase design or how data should be organized around user requirements. The general objective isto make information access, easy quick inexpensive and flexible for other users. During database

design the following objectives are concerned:- Controlled Redundancy Data independence Accurate and integrating More information at low cost Recovery from failure Privacy and security Performance Ease of learning and use

5. Testing

5.1 Introduction

Software testing is an investigation conducted to provide stakeholders with informationabout the quality of the product or service under test. [1] Software testing can also provide anobjective, independent view of the software to allow the business to appreciate and understand therisks of software implementation. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs (errors or other defects).

Software testing can be stated as the process of validating and verifying that a softwareprogram/application/product:

1. meets the requirements that guided its design and development;2. works as expected; and3. can be implemented with the same characteristics

5.2 Functional testingFunctional testing is a type of black box testing that bases its test cases on the

specifications of the software component under test. Functions are tested by feeding them inputand examining the output, and internal program structure is rarely considered

Functional testing typically involves five steps

1. The identification of functions that the software is expected to perform

2. The creation of input data based on the function's specifications

3. The determination of output based on the function's specifications

4. The execution of the test case

5. The comparison of actual and expected outputs

5.3 Structural testingWhite-box testing (also known as clear box testing, glass box testing, transparent box

testing, and structural testing) is a method of testing software that tests internal structures or

workings of an application, as opposed to its functionality (i.e. black-box testing) . In white-boxtesting an internal perspective of the system, as well as programming skills, are used to design testcases. The tester chooses inputs to exercise paths through the code and determine the appropriateoutputs. This is analogous to testing nodes in a circuit, e.g. in-circuit testing (ICT).

While white-box testing can be applied at the unit, integration and system levels of the softwaretesting process, it is usually done at the unit level. It can test paths within a unit, paths betweenunits during integration, and between subsystems during a systemlevel test. Though this methodof test design can uncover many errors or problems, it might not detect unimplemented parts of thespecification or missing requirements.

White-box test design techniques include:

Control flow testing

Data flow testing

Branch testing

Path testing

6. Implementation

Implementation is the stage in the project where the theoretical design is turned into aworking system. The implementation phase constructs, installs and operates the newsystem. The most crucial stage in achieving a new successful system is that it will workefficiently and effectively.There are several activities involved while implementing a new project they are

End user trainingEnd user EducationTraining on the application softwareSystem Design

Parallel Run and To New SystemPost implementation ReviewEnd user Training:

The successful implementation of the new system will purely upon the involvement of the officers working in that department. The officers will be imparted the necessary trainingon the new technology.End User Education:

The education of the end user start after the implementation and testing is over.When the system is found to be more difficult to under stand and complex, more effort isput to educate the end used to make them aware of the system, giving them lecturesabout the new system and providing them necessary documents and materials about howthe system can do this.

Training of application software: After providing the necessary basic training on the computer awareness, the users will

have to be trained upon the new system such as the screen flows and screen design typeof help on the screen, type of errors while entering the data, the corresponding validationcheck at each entry and the way to correct the data entered. It should then cover information needed by the specific user or group to use the system.Post Implementation View:

The department is planning a method to know the states of t he past implementationprocess. For that regular meeting will be arranged by the concerned officers about theimplementation problem and success
