Title of the project: Airline Reservations System (ARS)

1. Introduction :

This project deals with Airline Reservation System which is concerned with the reservation of tickets of airways. This project provides the basic requirement to cover all the module of reservation related to each planes available in list, to confirm the tickets, to modify the data related to passenger, to cancel the tickets if passenger wants.The history of airline reservations systems began in the late 1950s when American Airlines required a system that would allow real-time access to flight details in all of its offices, and the integration and automation of its booking and ticketing processes. As a result, Sabre (Semi-Automated Business Research Environment)was developed and launched in 1964. Saber’s breakthrough was its ability to keep inventory correct in real time, accessible to agents around the world. Prior to this, manual systems required centralized reservation centers, groups of people in a room with the physical cards that represented inventory, in this case, seats on airplanes.Airline Reservation System Provides an integrated and fully customized reservation system for complete management of an airlines inventory. The online reservation system combines with the airlines web site for a complete e-commerce solution. Call

centers will now have a complete and integrated solution for offering the airline product.

2. Requirement Analyses

It is very important and essential after requirement elicitation. We analyze, refine and synchronize the gathered requirement in order to make consistent and unambiguous requirement. This activates review all requirements and may provide a graphical view of the system.

Here we may also interact with the customer to clarify points of conclusion and to understand which requirement are most important than others.

entities outside the proposed system that interacts with the system. Example student result management system.

1.2 Develop Prototype –:One effective way to find out what customer really want is to construct a prototype something that looks a perfectly acts like the part of the system. We can use their feedback to continuously modify the prototype until the customer is satisfied. Hence, prototype helps the client to initialize the proposed system and increase the understanding to requirements. When developers and users are not curtained about some of requirements, a prototype may help both the parties to take a final decision.

1.3 Model the requirements -:This process usually consists of various graphical representations of functions, data entities, external entities and relationships between them. The graphical view may help to find incorrect, inconsistent requirements. Such model includes

2. Finalize the Requirements –:After modeling of requirements we will have better understanding of system behavior. The inconsistence and ambiguous have been identified and corrected. Flow of data among different modules has been analyzed. Elicitation and analyses activates have provided better inside to the system.

Future Scope of Airline Reservation SystemThe Airline Reservation System provided by the new-generation BPO service providers help airlines acquire a better efficiency with a cost control. With the rapid growth of outsourcing, the global management horizon has widened in the last few years. Outsourcing is gaining potential and you could refer to it as strategy management that sustains global growth. Along with it there is the competitive advantage to challenge the business complexities that arise. A small enterprise or a large international enterprise looks at outsourcing as a major growth engine with a scope for sophistication and specialization. The best part is that outsourcing saves a company and not just costs.

There are a number of upcoming BPO services catering to the Hospitality and the Airlines industry. The Airline Reservation System is generally a distribution system, web based, that helps airlines take the help of ecommerce to reduce the costs of distribution. It also provides customers and travel agencies with booking interfaces. The ADS or the Airline Distribution System provides all aspects of bookings, refunds and cancellations through various sources, websites/online presence, sales offices, corporate users, call centers, travel agencies, and MIS. In other words, they provide a strong, cost effective solution by which airlines can manage their sales, fares, flight schedules, and all related inventory of services. The ADS solution helps to serve all airlines globally with a cost effective advantage.

The Airline Reservation System brings in a multitude of user friendly features which are constantly undergoing a process of development. The multitude of tasks to keep the system streamlined and up to the mark involves the smooth running of a web-based reservation engine with a graphical interface that is user friendly. The system has great capabilities of inventory management. There is the authorization process that is taken care of by a reservation supervisor, e-ticketing system, departure control system that is integrated, communication system for the passengers along with an all inclusive capability of management reporting.

The Airline Distribution System operates on certain distinctive modules. It helps define all fares, routes, schedules for travel agents and other users. The

Reservation Module helps in modifying reservations for which the reservation agents could be present at any airline office. There is also the Travel Agent Module which can be set up for travel agents and help them with reservation capabilities on the internet. The travel agents in turn can display fares at a discount to the passengers. There is a user friendly passenger module with the help of which passengers can view their bookings online, make reservations and also make special requests on service and choose their options on the web. The complete automation of the passenger boarding system is managed by the Departure Control System.

Now airlines can know their customers better than ever before. The ARS has now made decisions regarding frequent flyer programs and other passenger reward programs easier to make than ever.

Airlines can use ARS tools to gain the competitive edge by analyzing market trends and determining yield trends.

System Development Life Cycle Model (SDLC)Waterfall Model

The most familiar model is the waterfall model. This model has five phases always occur in this order and do not overlap. The developer must complete each phase before next phase begins. This model is called because looks like waterfall that is step by step performing the steps.

Requirement Analyses and Specification Phase -:

The goal of this phase is to understand the exact requirement of the customer and to document them properly. This activity is usually executed together with the customer as the goal is to document all functions, performance and interfacing requirement of the software. This phase produces a large document written in natural language, contains a description of what a system will do without describing how it will be done. The resulting document is called Software Requirement

Specification (SRS). The SRS document may act as a contract between the developer and customer.

Design Phase -:

The SRS document is produced in the previous phase which contains the exact requirement of the customers. The goal of this phase is to transform the requirement specification into a structure that is suitable for implementation in some programming language. Here overall software architecture is defined. This work is documented and known as Software Designed Description (SDD).

Implementation and Unit Testing Phase -:

During this phase design is implemented if the SDD is complete the implementation or coding phase proceeds smoothly, because all information needed by the software developer is contained in the SDD.

Integration and System Testing Phase -:

This is a very important phase. Effective testing will contribute to the delivery of higher quality software products more satisfying users.

Operation and Maintenance Phase -:

Software maintenance is a task that every development group has to face when the software is delivered to the customer side, instead and is operational therefore released of software inaugurates the operation and maintenance. Software maintenance is very broad activity that including error correction, enhancement of capabilities, deletion of obsolete capabilities and optimization.

FEASIBILITY ANALYSES

Feasibility is the test of the system it helps in deciding whether it is viable to go through the project or not. Feasibility study studies the system & tells whether to develop the system or not. In lay mans terms it can be described as the test of the system & if the system passes in the test then it is viable to develop the project otherwise not or we can say feasibility study check’s whether project is feasible or not.

Feasibility has four solid dimensions:

1. Technology2. Finance

3. Time

4. Resources

The feasibility of the system “Airline Reservation System” is viewed with the help of these four dimensions.

Technology: This system uses one of the simplest technologies in use,

for the development purpose it uses simple to use & easily available technology. This system is based on windows like interface, which is very easy to use. The package is been developed for the department, which is not very familiar with software hence technology used, must be easily understandable, because of which windows like interface has been chosen. The technology used in this project is VB i.e. Visual Basics 6.0, M S Access & DAO controls. Visual Basic helps in providing windows like environment. This system uses menu-based approach in which everything is given with the help of menus.

Finance: This dimension measures the system in respect to money or we can say funds. This dimension checks whether its viable to spend the required amount on the system or it will be a waste. There is no problem of finance in this project because it uses simple technology, which is very easy to install. This system is been developed for a standalone computer hence for this system hardware requirement is very low. For this system to be developed &

installed properly we require very easily available technologies & very basic hardware and all these requirements doesn’t cost much.

Time: This particular dimension measures the systems worth in respect to time, which is one of the most important factors to be considered. In this project time factor is very important this system is scheduled to be installed in one month’s time. This system is not very big & hence can be completed within the time period it requires approx. 30 man-days of work. Time is a crucial factor to be considered & we can say this system can be developed within the required time period.

Resources: This dimension takes into count the recourses required to develop the system. For this particular system the resources required are quite nominal which can be fulfilled, the resources required for this system are basic hardware, an operating which is compatible with VB.

With the help of all these dimension we can measure the feasibility of the system & can decide whether to go forward with the project or not. By take in count the dimension & their role in this particular system we can say this system is feasible from all these dimension point of view & it is viable to go through the project.

Testing

Testing is the process of testing software products. Effective software testing will contribute to the delivery of higher quality software products, more satisfied users, lower maintenance cost, and more accurate and reliable results. However, ineffective testing will lead to opposite results, low quality products, unhappy users, and increased maintenance costs, unreliable and inaccurate results.

Acceptance Testing

This term is used when the software is devolved of a specific customer. A series of tests are conducted to enable the customer to validate the requirements. These tests are conducted by the end user or customer and may range from adhoc tests. Acceptance Test may be conducted for few weeks or months. The discovered errors will be fixed and better quality software will be delivered to the customer.

Alpha and Beta Testing

The Alpha tests are conducted at the developer site by a customer. These tests are in a controlled environment. Alpha testing may be started when formal testing process is near completion.

The Beta tests are conducted by the customers or end users at their sites. Unlike alpha test the developer is not present here. Beta testing is conducted in a real environment that cannot be controlled by the developer. Customers are expected to report failures, if any, to the company. After receiving such failures reports developers modify the code and fix the bug and prepare the product for final release.

Functional Testing

A strategy were testing is based on functionality of the program and is known as functional testing. Thus functional testing refers to testing, involves only observation of the output for certain input values. There is no attempt to analyze the code, which produces the output. We ignore the internal of the code therefore; functional testing is also referred to as Block Box Testing in which contents of the bock box are not known. Functionality of the block box is understood completely in terms of inputs and outputs.
