Alltheseandothertransactionsandfeatureshavebeendescribedindetailinthefollowingsection.

1.1 The Airline Reservation System (ARS) is a software application to assist an airline with transactions related to making ticket reservations, which includes blocking, reserving, canceling and rescheduling tickets.

1.2From the viewpoint of the airline -

1.2.1Minimize repetitive work done by the system administrator and reservation clerks.

1.2.2Maintain consistency among different access modes, e.g. by phone, , at the information desk and across different physical locations. The users should be basically taken through the same steps by the system as they go through in conventional desk-reservation systems.

1.2.3Maintain customer information in case of emergency, e.g. flight cancellation due to inclement weather. The profile can also be used by the airline company to track user preferences

1.2.4 Maximize the revenue of the airline company by various means:

1.2.4.1Increase awareness among frequent travelers about various special offers and discounts.

1.2.4.2Minimize the number of vacant seats on a flight and maximize flight capacity utilization.

1.2.4.3Maintain the capability to adopt a flexible pricing policy. The price of the tickets should be dynamically determined based on how early, before the date of departure, the customer buys the ticket.

1.3A survey conducted by airline companies shows that users of an existing reservation system would respond favorably to an ARS that satisfied or helped them satisfy the following objectives:

1.3.1Reduce effort and frustration for travelers in scheduling a trip, especially by reducing the search effort for the flight they need to take.

1.3.2Show all possible combinations and itineraries available for a pair of origin-destination cities.

1.3.3Reduce redundancy in the information required from the customers in order for them to buy tickets, create user accounts etc.

1.3.4Check the validity of input data and give a feedback to the user in case of errors or inconsistency.

1.3.5Provide flexible access modes to users internet, telephone, PDA.

1.3.6Protect customers privacy concerns.

1.3.7Make it easy for travelers to check the ticket status or make changes to their trip.

The definition of our problem lies in manual system and a fully automated system.

Manual system : The system is very time consuming and lazy. This system is more prone to errors and sometimes the approach to various problems is unstructured.

Technical system : With the advent of latest technology if we do not update our system then our business result in losses gradually with time. The technical systems contains the tools of latest trend i.e. computers printers, fax, Internet etc. The systems with this technology are very fast, accurate, user-friendly and reliable..

Need of Airlines system

A few factors that directs us to develop a new system are given below -:

1) Faster System

2) Accuracy

3) Reliability

4) Informative

5) Reservations and cancellations from any where to any place

FEASIBILITY STUDY :-Feasibility study before development or customization of software we think following of the major points, which includes following: -

a) Economical

b) Technical

c) Duration

Economical :-This study about the software basically give the suggestion like if we develop software for our organization than how much it will forfeitable, workable as well as economical. If we developing a software which very economical but not profitable there it is also wrong decision. So for we economical study about the system table following of the point.

How much costing of the software?

What is the output of the customization?

What are the advantages in c0ompression manual we check

whether it is time or not?

Whether it is use friendly or not?

It is mountable for long term.

Understanding about the software

Corrective of software.

Technical :-We also consider some technical points about development of software.

We see whether the software is reliable or not.

Whether it is work time for long time or not.

What are the languages as well as OS is used for development of software.

It provides security or not.

Software is reusable or not.

Software is updated or not.

Software is flexible or not whether software can maintain.

Duration :-It is also a major point when we develop software. We also consider about time, how much time software place to complete because for a big organization time factor is money for full successful of the software also Tax some times so we have consider from starting to last that means beginning to software.

Fare details

In developing cost estimates for a system, we need to consider servable cost elements. Among them hardware, personnel, facility, operating, & supply costs.

Hardware Cost :-Hardware cost relate to the actual purchase or lease of the computer & peripherals Ex. Printer, disk, floppy drive, the best way to control for this cost is to treat it as an operating cost.

Personnel Cost :-This includes staff salaries & benefits (health insurance, vocation time, sick pay etc.) as well as pay for those involved in developing system. Costs incurred during the development of a system are one time costs & are labeled developmental costs. Once the system is installed the costs of operating &maintaining the system become recurring costs.

Facility Costs :-Facility costs are expenses incurred in the preparation of the physical site where the application or the computer will be i operation. This includes wiring, flooring, acoustics, lighting & air conditioning. These costs are treated as one time costs.

Operating Cost :-Operating costs include all costs associated with the day to day operating system.The amount depends on the number of sifts the nature of the application & the caliber of the operating staff. There are various ways of covering operating costs to overhead. Another approach is to change each authorized user for the amount of processing they request from the system. The amount charged is based on the computer time, staff time & the volume of output produced.

Supply Cost :-These costs are variable costs that increase with increased use of paper, ribbon, disks & the like they should be estimated & include in the overall cost of the system.

Equipment Cost :-Equipment costs include rental & annual deprecation of any equipment such as typewriter, copies, computer terminals & microcomputers used in connection with the system. Other costs associated with the equipment, such as insurance & maintenance should also be included.

SYSTEM :-A system can be defined as A set of arrangement of elements that are organized to accomplish some method, procedure or control by processing information.

System Analysis stages down the broad frame work of strategy stage into its minute details. This is the stage where intensive user interaction assumes a lot of importance.

System Development :-Development Phase, translates a set of requirements into an operational system that we call Software. At early stages of hardware development a hardware engineer does not reach for a soldering iron, similarly the Software engineer

should not reach the compiler. Design is accomplished first.

The first phase of development concentrates on design. The design phase for software with a description of architecture and data design. That is a modular structure is developed first, interfaces are defined and data structure is established. Design criteria are used for the assessment of quality. This preliminary design step is reviewed for completeness and tractability to software requirements.

Procedural aspects of each modular component of the software design are considered next, and is following by the CODING the generation of program using an appropriate programming language or CASE tool occurs after the design is complete. Software engineering methodology views coding as a consequence of good design. Code is then reviewed for style and clarity, but should otherwise be directly traceable to a detailed design description.

DETAILED ENTITY RELATIONSHIP DIAGRAM :-

Identification of all the Entities of importance for which data need to be stored and defined their relationship with each other was a major task at this level. All the identified entities were mapped on a E-R-diagram. It is of utmost importance to cover all the necessary entities and defined their relationship with each other correctly because any errors at this stage would result in the reworking in the further stages.

Unique Identification, UID :-A unique identification is required to be identified and associated with each other at this stage.

Function Hierarchy :-Function hierarchy Is used for grouping related functions under a parent function. The hierarchy is balanced so that all elementary functions comes in the same level of hierarchy. A good hierarchy drawn at this stage helped in menu generation at a later stage.

The Basic Objective :-The basic objective of the system design was the system being developed should be able to fit into the existing system, that is it become a part of the system and it should not lead to any changes which can adversely affect the existing system. The airways having many activities which effect one another so the approach of airways reservation is generated for the simplification of data handling.

The approach would bring in the following benefits :- Standardization of the methods and procedures.

Availability of information centrally.

Minimizing future maintenance requirements.

Reduction in the learning process for new personal.

Packaged systems :-The systems would have the following features:- Completely menu drive interface with the provision of initiating even the batch jobs by the user himself.

On Line help

Strong documentation

Validation checks done by the system itself

Minimization of input to the system to produce maximum output.

Designing is the most important part of the software development. It requires a careful planning and logical thinking on the system designer. Designing a software means to plan how the various parts of the software are going to achieve the desired goal. It should done with the utmost care because if this phase contains any errors then that will be going to affect the performance of the system, as a result it may take more processing time, more coding, extra work load etc.

As the software is to be designed in MS-ACCESS RDBMS, the concept of the database is must for quality designing. It will be designing of the database, designing of forms, designing of reports.

Separate tables have been created for each entity of the system. In order to make the response time negligible, all the tables have been created in the Memory File System. Moreover indexes have been created on the tables in the number of records have been made random.

The design stages takes the final specification of the system from the analysis stages and finds the best way of fulfilling them, given the technical environment and previous decision on required level of automationThe system design is carried out in two phases :- Architectural Design Detailed Design

ARCHITECTURAL DESIGN :-The high level design maps the business system described in the program requirement specification to logical data structure, it involves:Identification of the entities that constitutes the system :-All the entities related to the module were identified, checked and consolidated

Identifying the Relationships :-The relationships between the entities, within and outside the system were identified.

Attribute definition:-The pertaining of the entities was identified and their field characteristics were specified.

Normalization :-

The entities were normalization, after first and the second normalization was achieved for all the entities.

Interface :-Interface with the other systems were done and attributes related to external entities identified.

DETAILED DESIGN :-The low level design maps the logical model of the system to a physical database design.

Table Mapping :-The Table was created for the system using the design view, which is the part of the MS_ACCESS. This has provision to create the entities and attributes into the Tables. The name of the entity is taken as the table name.

Default Database Design :-In Access we can create the tables very easily. The tables divide into two parts. These names are as follow: -

ROWS

COLUMNSThe steps involved here were :-1. Generation of table

2. Check Validation Rule

3. Check Validation Text

4. Primary Keys

5. Unique Keys

6. Foreign Keys

Relationship :-Ms-Access allows many types of relationship between the tables. These relationship names are as follow: -

One to One Relationship

Many to One Relationship

Many to Many Relationship

Program specifications :-The program specifications were written for the master, transactions, reports and queries. The logic for each field, block and form were written so that anyone who does not know the system will be able to code the logic. Field validations and user-friendly error messages were written as part of the program specification.

WINDOW 98 used as PLATFORM

Windows 98 is latest version of windows and also GUI. This is best then another Operating system and easy.

Windows 98 has come up with another bonanza, that is, Network Communication with other users. The users can connect with other users to share data files and peripheral devices, like Printers.

The Communication tools of Windows 98 include E-Mail and connection to Internet.

VISUAL BASIC used as FRONT ENDVisual Basic uses front-end programming because VB use Back end as like MS-ACCESS and any other Database.

In VB we can use easy database connectivity and design the Form, Report, and others MDI applications with the help of Database.

VB facility the database controls which helps the changing, modifying, deleting and adding facility in database with the help of command buttons and controls.

VB is used for see the Data in many modes such as with the help of MSFlexiGrid Controls, Textbox, Combo box, List box, Image, Picture control and other.Visual Basic gives the different types of accessing the Database (RDO, ADO and DAO)Visual Basic is complete programming language that supports programming constructs for looping, decision making and efficient processing. These constructs include

For.next

Do.loop

Selectcase

Withend with

If.then.else

Visual Basic helps of creation Menus, Master-Details Form.

MS-ACCESS 2007 used as BACK END

Ms-Access is a database and partially RDBMS. In Access we can easily create Database design and give the validations. Access allows the many types of relations between the tables.

Access used as Backend with the Visual Basic. Access allows creating the Primary Key, Foreign Key and Unique Key. In Access we can store the data in to the table for using the wizard options.

During system testing, the system is used experimentally to ensure that the software does not fall, i.e. it will run according to specification and in the way users expect. Special test data input for processing and the result examination. A limited number of users may be allowed to use the system so that analysis can seen whether they use it in unforeseen ways. It is preferable to discover any surprises the organization implements the system and encounters them later on. This type of testing which allows only a few, selected users to work on the system is known as BETA TESTING. On the other hand the testing done by the developer (s), themselves is known as ALPHA TESTING.

Testing is generally performed by persons other than those who the original programs to ensure complete and unbiased testing and more reliable software.

The norms followed during the testing phase were thoroughly tested by me, the developer, I was required to release the programs source code. The source code was copied into the area. If some changes were desired in the program, I was suitably informed and was required to made the necessary modifications.

Following testing procedures were used

UNIT TESTING

Unit testing is the testing of a single program module in an isolated environment. The testing of the processing procedure is the main focus. In this regard, all the modules were separately tested first as isolated and complete entities. This helped a lot in discovering problems related to a single module and rectifying them in the contest of the module itself, rather than considering module-related problem in a global context.

INTEGRATION TESTING

Integration testing is the process of testing the interfaces among system modules. Some testing ensures that data moves between system as intended. In the regard of a particular module was obtained in correct format, so that the next module could accept it appropriately. This could be done either after the entire system was developed, or in stages than one module was developed.

SYSTEM TESTING

System testing is the testing of the system against its initial objectives. Such testing is done either in a simulated environment or in a live environment.

In the case of the system which I developed, the testing was done in a pseudo-real environment. The organization has an area called the Development , where all development work is carried out, whereas the Client is the area where all on-line work is undertaken. Since the kind of work which I was involved dealt with insertion, updating and in tables, all the work was developed in the Development area. I call the environment pseudo-real since all data which is being used for on-line transaction can be copied into the tables of the Development and live data can be worked on. Thus whatever would be the output on the Client is reflected exactly on the Development also. Thus, discovery of error became simpler in that the errors which would occurs in the real-time environment were exactly duplicated in the Development environment.

All the above types of testing were carried out and various extreme cases were also introduced to check for whether the system responded as expected. The various Forms, database packages, procedures, function; visual basic programs and functions were tested to discover they behaved in the manner expected of them and gave accurate results. However, the factor, which helped most in the modification and rectification of the system, was the user response. The user after using the system would invariably come up with some idea to improve the system. Such ideas, if feasible, were incorporated into the system, thus leading to an improvement in the overall efficiency of the system.

Implementation, literally, means to put into effect or to carry out. The system implementation phase of software engineering deals with all activities that take place to convert from the old system to the new. Proper implementation is essential to provide system to meet organizations requirements.

During the implementation phase debugging, documentation of the system was created out, module in the project for

Accuracy of Results,

Minimization of response Time,

Clarity and Simplicity of the code,

Minimization of Hard Coding i.e. (a generic approach was followed )

Minimization of amount of memory used.

Various types of errors were discovered while debugging the modules. These ranged from errors to failure to account for various processing cases. Proper documentation of each module was done by embedding comments in the executable portion of the code. To enhance the readability, comments, indentation, parenthesis, black spaces, blank lines and borders were around the blocks of comments. Care was taken to use descriptive names for table, field, modules, forms etc., The proper use of indentation, parenthesis and blank lines was also ensured during coding.

Testing of the Report Generation module was carried out to find out the response time of the system for the generating reports. To make the response time negligible

Maintenance is a fact of life in the development of information systems. However the making of changes & adjustments dont necessarily signal correction of error or the occurrence of problems.
