PREFACE
Computer Programming is an art. It is a way of explaining how a specific task is to be
performed by a given computer driven by speedy development in the underlying hardware, compile programs have become considerably complex and bigger.
Contrary to popular belief computer programming can be both fun and an excellent opportunity
to exercise your mind, creativity and imagination. It gives us the power to instruct computers according to our will. With highly powerful work horses at disposal, there is no limit to what we can do with the help of programming languages. The only limit being our own imagination.
Computer programming is that art which creates an artist in you and increase the capability of
imagination…
We again convey our thanks to Ms. Anjali Singh for their great guidance and precious time
without this it is impossible for us to complete the project.

HOTEL MANAGEMENT SYSTEM
INTRODUCTION This project is aimed at developing a system that is an easy to operate user friendly,economically priced software that commited to meet the all requirements to manage small,medium and big scale hotels..I have tried my best to make the complicated 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 not have any difficulty in using this package & further expansion is possible without much effort. Even though I cannot claim that this work to be entirely exhaustive, the main purpose of my exercise is perform each Employee’s activity 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 two types of users i. Online Users. ii. Administrator (management of the Hotel). Online users can see the required articles or news Administrator can maintain daily updates in the hotel records. Administrator is must be an authorized user. He can further change the password. There is the facility for password
recovery, logout etc. The main aim of the entire activity is to automate the process of day to day activities of Hotel like Room activities, Admission of a New Customer, Assign a room according to customer’s demand, checkout of a computer and releasing the room and finally compute the bill etc. The limited time and resources have restricted us to incorporate, in this project, only a main activities that are performed in a HOTEL Management System, but utmost care has been taken to make the system efficient and user friendly. “HOTEL Management System” has been designed to computerized the following functions that are performed by the system: Room Detail Functions Opening a New Room Modification to room assigned Check-in and check-out Detail Functions Admission of New customer Check-out of customer Room assigning related to customer’s need. Statement of Customer Details Check-in customer Check-out customer Room Details Total number of Customers in the Hotel Individual customer Report OBJECTIVE During the past several decades personnel function has been transformed from a relatively obscure record keeping staff to 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 important resources. 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 the correct statement calculation and generation. T his project intends to introduce more user friendliness in the various activities such as record updation, maintenance, and searching. T he searching of record has been made quite simple as all the details of the customer can be obtained by simply keying in the identification of that customer. S imilarly, record maintenance and updation can also be accomplished by using the identification of the customer with all the details being automatically
generated. These details are also being promptly automatically updated in the master file thus keeping the record absolutely up-to-date. T he entire information has maintained in the database or Files and whoever wants to retrieve can’t retrieve, only authorization user can retrieve the necessary information which can be easily be accessible from the file. T he 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 customer’s demand, 4. Checkout of a computer and releasing the room 5. Finally compute the bill etc. 6. Packages available. 7. Advance online bookings. 8. Online Cancellation. 9. List of Regular customers. 10. Email facility. 11. Feedbacks This project have some more features: S ystem Connectivity N o data duplication N o Paper Work Required T ime Efficient Cost Efficient Automatic data validation U ser friendly environment Data security and reliability F ast data insertion & retrieval E asy performance check SCOPE I have designed the given proposed system in the JSP to automate the process of Hotels. This project is useful for the authorities which keep track of all the users registered in a particular state .The authority can add hotel packages, room details, availability of rooms, online 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 all activities. The manual handling of the record is time consuming and highly prone to error. To improve the performance of the Hotel Management System, the
computerized system is to be undertaken. This project is fully computerized and user friendly even that any of the members can see the report and status of the company. Efficiency: The basic need of this website is efficiency. The website should be efficient so that whenever a new user submits his/her details the website 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 the password to access this project and illegal access is not supposed to deal with. All the control is under the administrator and the other members have the rights to just see the records not to change any transaction or entry. Security: Security is the main criteria for the proposed system. Since illegal access may corrupt the database. So security has to be given in this project. Scope of Future Application This project can be used in the hotel after adding some more useful modules in the project for which hotel are providing services. Utmost care and back-up procedures must be established to ensure 100% successful implementation of the computerized hotel system. In case of system failure, the organization should be in a position to process the transaction with another organization or if the worst comes to the worst, it should be in a position to complete it manually. Scope of Improvement Now a days hotel are providing many other facilities, this project can also be improved with the improvement in the Hotels. Utmost care and back-up procedures must be established to ensure 100% successful implementation of the computerized banking system. In case of system failure, the organization should be in a position to process the transaction with another organization or if the worst comes to the worst, it should be in a position to complete it manually.
SOFTWARE & HARDWARE REQIREMENT: I used TURBO C and Windows XP with using Microsoft World to develop this software. So I have tested this on the above configuration. But it can be run on any system which contains following requirements.
Minimum Software Requirements: 1. Windows 98 or Higher (Windows XP or 2000). 2.turbo c. 3. MicroSoft Office Picture Editor.
Minimum Hardware Requirements:
1. 3MB free Space on Harddisk (for Software) 2. Mouse & Keyboard (For Software Instruction) 3. CD-Rom or Any Installation Media 4. VGA or SVGA for Graphics SYSTEM DEVELOPMENT LIFE CYCLE The systems development life cycle is a project management technique that divides complex projects into smaller, more easily managed segments or phases. Segmenting projects allows managers to verify the successful completion of project phases before allocating resource to subsequent phases. Software development projects typically include initiation, planning, design, development, testing, implementation, and maintenance phases. However, the phases may be divided differently depending on the organization involved. For example, initial project activities might be designated as request, requirements-definition, and planning phases, or initiation, concept-development, and planning phases. End users of the system under development should be involved in reviewing the output of each phase to ensure the system is being built phase to ensure the system is being built to deliver the needed functionality.
.
Phases Of System Development Life Cycle Initiation Phase The Initiation Phase begins when a business sponsor identifies a need or an opportunity. The purpose of the Initiation Phase is to: 1>Identify and validate an opportunity to improve business accomplishments of the organization or a deficiency related to a business need. 2>Identify
significant assumptions
and constraints on solutions to that need.
3>Recommend the exploration of alternative
concepts and methods to satisfy the need including
questioning the need for technology, i.e., will a change in the business process offer a solution? 4>Assure executive business and executive
technical sponsorship.
The Sponsor designates a Project Manager and the business need is documented in a Concept Proposal. The Concept Proposal includes information about the business process and the relationship to the Agency/Organization Infrastructure and the Strategic Plan. A successful Concept Proposal results in a Project Management Charter which outlines the authority of the project manager to begin the project. Careful oversight is required to ensure projects support strategic business objectives and resources are effectively implemented into an organization's enterprise architecture. The initiation phase begins when an opportunity to add, improve, or correct a system is identified and formally requested through the presentation of a business case. The business case should, at a minimum, describe a proposal’s purpose, identify expected benefits, and explain how the proposed system supports one of the organization’s business strategies. The business case should also identify alternative solutions and detail as many informational, functional, and network requirements as possible. System Concept Development Phase The System Concept Development Phase begins after a business need or opportunity is validated by the Agency/Organization Program Leadership and the Agency/Organization CIO. The purpose of the System Concept Development Phase is to: 1>Determine
the feasibility and appropriateness of the alternatives.
2>Identify system interfaces. 3>Identify identify 4>Evaluate
basic functional and data requirements to satisfy the business need. Establish system boundaries, goals, objectives, critical success factors, and performance measures. costs and benefits of alternative
5>Assess project risks.
approaches to satisfy the basic functional requirements .
6>Identify and initiate risk mitigation actions, 7>Develop high-level technical architecture,
and process models, data models, and a concept of operations.
This phase explores potential ,technical solutions within the context of the business need. It may include several trade-off decisions such as the decision to use COTS software products as opposed to developing custom software or reusing software components, or the decision to use an incremental delivery versus a complete, one- time deployment. Construction of executable prototypes is encouraged to evaluate technology to support the business process. The System Boundary Document serves as an important reference document to support the Information Technology Project Request (ITPR) process. The ITPR must be approved by the
State CIO before the project can move forward.
Planning Phase The planning phase is the most critical step in completing development, acquisition, and maintenance projects. Careful planning, particularly in the early stages of a project, is necessary to coordinate activities and manage project risks effectively. The depth and formality of project plans should be commensurate with the characteristics and risks of a given project. Project plans refine the information gathered during the initiation phase by further identifying the specific activities and resources required to complete a project. A critical part of a project manager’s job is to
coordinate discussions between user, audit, security, design, development, and network personnel to identify and document as many functional, security, and network requirements as possible. During this phase, a plan is developed that documents the approach to be used and includes a discussion of methods, tools, tasks, resources, project schedules, and user input. Personnel assignments, costs, project schedule, and target dates are established. A Project Management Plan is created with components related to acquisition planning, configuration management planning, quality assurance planning, concept of operations, system security, verification and validation and systems engineering management planning.
Requirements Analysis Phase This phase formally defines the detailed functional user requirements using high-level requirements identified in the Initiation, System Concept, and Planning phases. It also delineates the requirements in terms of data, system performance, security, and maintainability requirements for the system. The requirements are defined in this phase to a level of detail sufficient for systems design to proceed. They need to be measurable, testable, and relate to the business need or opportunity identified in the Initiation Phase. The requirements that will be used to determine acceptance of the system are captured in the Test and Evaluation Master Plan. The purposes of this phase are to: 1>Further define and refine the functional and data requirements and document them in the Requirements Document, 2>Complete business process reengineering
of the functions to be supported (i.e., verify what information
drives the business process, what information is generated, who generates it, where does the information go, and who processes it), 3>Develop detailed data and process models
(system inputs, outputs, and the process.
4>Develop
the test and evaluation requirements that will be used to determine acceptable system
performance. Design Phase The design phase involves converting the informational, functional, and network requirements identified during the initiation and planning phases into unified design specifications that developers use to script programs during the development phase. Program designs are c onstructed in various ways. Using a top-down approach, designers first identify and link major program components and interfaces, then expand design layouts as they identify and link smaller subsystems and connections. Using a bottom-up approach, designers first identify and link minor program components and interfaces, then expand design layouts as they identify and link larger systems and connections. Contemporary design techniques often use prototyping tools that build mock-up designs of items such as application screens, database layouts, and system architectures. End users, designers, developers, database managers, and network administrators should review and refine the prototyped designs in an iterative process until they agree on an acceptable design. Audit, security, and quality assurance personnel should be involved in the review and approval process. During this phase, the system is designed to satisfy the functional requirements identified in the previous phase. Since problems in the design phase could be very expensive to solve in the later stage of the software development, a variety of elements are considered in the design to mitigate risk. These include: 1>
Identifying potential risks and defining design features.
2>
Performing a security risk assessment.
3>
Developing a conversion plan to migrate
4>
Determining the operating environment.
5>
Defining major subsystems and their
6>
Allocating processes to resources.
7>
Preparing detailed logic specifications for
current data to the new system.
inputs and outputs.
each software module.
The result is a draft System Design Document which captures the preliminary design for the system. Everything requiring user input or approval is documented and reviewed by the user. Once these documents have been approved by the Agency CIO and Business Sponsor, the final System Design Document is created to serve as the Critical/Detailed Design for the system. This document receives a rigorous review by Agency technical and functional representatives to ensure that it satisfies the business requirements. Concurrent with the development of the system design, the Agency Project Manager begins development of the Implementation Plan, Operations and Maintenance Manual, and the Training Plan.
Development Phase
The development phase involves converting design specifications into executable programs. Effective development standards include requirements that programmers and other project participants discuss design specifications before programming begins. The procedures help ensure programmers clearly understand program designs and functional requirements. Programmers use various techniques to develop computer programs. The large transaction-oriented programs associated with financial institutions have traditionally been developed using procedural programming techniques. Procedural programming involves the line-by-line scripting of logical instructions that are combined to form a program. Effective completion of the previous stages is a key factor in the success of the Development phase. The Development phase consists of: 1>Translating the detailed requirements and design into system components. 2>Testing individual elements (units) for usability. 3>Preparing for integration and testing of the IT system. PROJECT CATEGORY This Project is coupled with material on how to use the various tool, subsets available in JSP, SERVLETS AND MY SQL. The need of today’s software development is competence in a GUI based front-end tool, which can connect to Relational Database engines. This gives the programmer the opportunity to develop client server based commercial applications. These applications give users the power and ease of a GUI with the multi user capabilities of Novell, UNIX or WinNT based RDBMS engines such as MY SQL . All the important coding techniques used by programmers, in OOPS based coding is brought out in full and in great detail.
System Study & Analysis PRINCIPLES OF SYSTEM ANALYSIS 1. Understand the problem before you begin to create the analysis model. 2. Develop prototypes that enable a user to understand how human machine interaction will occur. 3. Record the origin of and the reason for every requirement. 4. Use multiple views of requirements like building data, function and behavioral models. 5. Work to eliminate ambiguity. ENTITY RELATIONSHIP DIAGRAM (ERD) 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 a data 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 reference within 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. 13 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.

Integration and Test Phase :Subsystem integration, system, security, and user acceptance testing is conducted during the integration and test phase. The user, with those responsible for quality assurance, validates that the functional requirements, as defined in the functional requirements document, are satisfied by the developed or modified system. OIT Security staff assess the system security and issue a security certification and accreditation prior to installation/implementation. Multiple levels of testing are performed, including:
1>Testing at the development facility by the 2> Testing as a deployed system with end
contractor and possibly supported by end users. users working together with contract personnel.
3> Operational testing by the end user alone
performing all functions.
Requirements are traced throughout testing, a final Independent Verification & Validation evaluation is performed and all documentation is reviewed and accepted prior to acceptance of the system. • Implementation Phase:This phase is initiated after the system has been tested and accepted by the user. In this phase, the system is installed to support the intended business functions. System performance is compared to performance objectives established during the planning phase. Implementation includes user notification, user training, installation of hardware, installation of software onto production computers, and integration of the system into daily work processes. This phase continues until the system is operating in production in accordance with the defined user requirements. • Operations and Maintenance Phase :The system operation is ongoing. The system is monitored for continued performance in accordance with user requirements and needed system modifications are incorporated. Operations continue as long as the system can be effectively adapted to respond to the organization’s needs. When modifications or changes are identified, the system may reenter the planning phase. The purpose of this phase is to: 1>Operate, maintain, and enhance the system . 2>Certify that the system can process sensitive information. 3>Conduct periodic assessments of the system to ensure the functional requirements continue to be satisfied. 4>Determine when the system needs to be modernized, replaced, or retired.
OUTPUT UNIT Function Details 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 customer requirement, and finally compute the bill etc. which has to be performed repeatedly on regular basis. To provide efficient, fast, reliable and user-friendly system is the basic
motto 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 password and the software checks its validity. If the password is valid then option is given to change the password, otherwise “Invalid User/Password” message is displayed. There is an option for password recovery, log out, login, new users sign in. The Administrator can 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 the details.
