AIRLINE RESERVATION SYSTEM

ABSTRACT:

The aim of this software is to develop a systematic analysis of the procedure involved in the reservation of ticket for railway travel. This should be used in an effective way so that various advantages are obtained from the software. Software means establishment of sound and in-depth development of a task using high-level language that results in well-equipped, economical software, which is reliable. The introduction may be divided into various steps based on the developer and also depending upon the operation to be performed using the particular software. The “AIRLINE RESERVATION SYSTEM” undertakes as a project I based on relevant technologies. The main aim of this project is to develop the software for the process of reserving airway ticket should lead to increased efficiency and reduced drawbacks which were present in the previous procedure of airline reservation. The software should be, error controlled both logically as well as in syntactic manner. The features deal with the different operations involved in the process of AIRLINE RESERVATION. Business people don’t have any planned air travel. They just receive the invitation for some international exhibition at the last minute, which they should or can attend to improve their ability both in the skilled manpower and also in the machinery importing. Tickets can now be booked online. Some agents or the organization with the idea of eyeing increased profit through the extra taxes for the comfort they give to buy the ticket just by a single click of the mouse.

REQUIREMENT ANALYSIS

Requirements are prone to issues of the ambiguity, incompleteness and inconsistency techniques such as rigorous inspection have been shown to help deal with these issues.Ambiguity, incompleteness and inconsistencies that can be resolved in the requirement phase typically cost orders of the magnitude less to correct than when these same issues are found in later stages of product development.The purpose of developing the specified software is to describe the analysis involved in the reservation of air ticket.

FUNCTIONAL ANALYSIS

Input: Collecting the information of the person who is going to travel.Output: The issue of ticket on the particular date specified by the traveler.

PROCESS

Enter the details of the traveler. Check for availability of tickets. Inform the traveler the position of the available seat. Ask his/her decision whether to reserve the ticket or not. Positive reply-book ticket after receiving the amount for the cost of ticket. Issue the ticket.

Ask the traveler to check in time so that he/she doesn’t miss the plan because of delay. Update the database before the next booking is to be done.

EXISTING SYSTEMIn the existing system there is no provision for senior citizen concession and there is no facility for viewing single passenger record.

PROPOSED SYSTEM

The main implementation requirements for this project are

The client tier must not be changed, which means that the format of all the communication messages have to be preserved.

Some functionality, like check digit validation, time, stamps etc. Are supplied by already existing routines which we are obliged to use. The format of communication in modules are fixed and non changeable. All the technical documentation formats are also fixed and have to be followed. Some customer implementation techniques have to be followed. A facility for viewing the single passenger record is made available. We have made concession in ticket fair for senior citizens.

DESIGN CONCEPT

The algorithm is developed as flow chart and the data flow diagrams, to describe the step-wise procedure of the application. The basic requirements, which are got from the customer, should all be covered in this algorithm developed. Most components described in the system architecture section will require a more detailed discussion. Other lower-level components may need to be described as well. The kind of component, such as a subsystem like delete, insert, module like student detail, class like library, package, function, file etc.The specific purpose and semantic meaning of the component describe this. This may need to refer back to the requirement specification.

REPORT MODULE

The tickets issued should have the details such as plane number, ticket number, seat number, traveler’s name, time of departure. The traveler should be informed about the check-in time.The names of the fields involved in the airline reservation system are

FLIGHT DETAILS CHECK AVAILABILITY BOOK TICKET VIEW SINGLE PASSENGER RECORD(by taking the ticket number)

EXIT

MODULE 1:FLIGHT DETAILS

This module is used to view the flight details with ease and it tends the passenger to book tickets without much difficulty.

MODULE 2:CHECK AVAILABILITY

This module is used to check the availability of the flights and the information of the seats in that flight.

MODULE 3:SINGLE PASSENGER RECORD

This module is used to view the single passenger details with the help of the ticket number issued after booking with input support information.

MODULE 4:BOOK TICKET

This module is used to book the ticket after checking the availability of tickets I the flights. A ticket can be booked to a maximum of five just by entering the passenger name, age and their details.

MODULE 5:EXIT

This module is used to exit from the reservation form.

ERD (Entity Relationship Diagram)

The object relationship pair can be graphically represented by a diagram called Entity Relationship Diagram. It is mainly used in database applications but now it is more commonly used in data design. The primary purpose of ERD is to represent the relationship between data objects.

Various components of ERD are:

1. Entity 2. Relationship 3. Attribute.

DFD (DATA FLOW DIAGRAM)

Data Flow Diagram is one of the Functional Model which are used to represent the flow of information in any computer based system. Three Generic Functionalities:

1. Input 2. Process 3. OutputThe data flow diagram depicts the information flow and the transforms that are applied on the data as it

moves from input to output.

IMPLEMENTATION:

Implementation is the realization, application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy.

The design must be translated in to a machine-readable form. The code generation step performs this tasks .If design is performed in a detailed manner, code generation can be accomplished mechanistically.

TESTING ANALYSIS

BLACKBOX TESTING: The black box testing is used to demonstrate that the software functions are

operational. As the name suggests in black box testing it is tested whether the input is accepted properly and output is correctly produced. The major focus o block box testing is on functions, operations, external interfaces, external data and information.

WHITEBOX TESTING In white box testing the procedural details are closely examined. In this testing

the internals of software are tested to make sure that they operate according to specifications and designs. Thus major focus of white box testing is on internal structures, logic paths, control flows, data flows, internal data structures, conditions, loops, etc

MAINTENANCE

In software engineering the software maintenance is the process of enhancing and optimizing deployed software as well as remedying defects.

Software maintenance is one of the phases in the software development process and follows deployment of the software into the field. The software maintenance phase involves changes to the software in order to correct defects and deficiencies found during the field usage as well as the addition of new functionality to improve the software usability and applicability.

CONCLUSION:

When looking for solid AIRLINE RESERVATION SYSTEM software, you want to find a solution that gives you the easy way of booking ticket. Naturally, you first want to find the software that meets your needs, both now and in the future. Engineering is based on designing different projects. Nowadays,” most products and systems are becoming more complex in nature, and there is an increasing demand relative to new technology applications at a time when our natural resources are dwindling” now that’s where engineering jumps in. Business depending on natural resources is no longer in a safe position. Engineering and engineers are not only useful for the technologies and machineries in the business world, but it is also constructive in different components of business such as entertainment, telecommunication and etc
