SYNOPSIS

ANALYSIS:

System analysis is the term used to describe the process of collecting analyzing

facts in respect of existing operation of the situation, prevailing so that an effective

computerized system may be designed and implemented if proved feasible .

DESIGN:

System analysis also embraces system design, which is an activity concerned with

the design of a computerized application based on the facts disclosed during the

analysis stage. Both activities are carried out by the same person who is known as

System Analyst.

System design: up to the time of the systems proposal, analysts have concerned

themselves with the local design of the system.

TESTING:

There are two basic approaches to testing functional and structural. Functional

testing is also called Black Box Testing. In Black Box Testing the structure of the

program is not considered structural testing it is called white Bon testing.

INTRODUCTION

The Airline Reservation System (ARS) was one of the earliest changes to improve

efficiency. ARS eventually evolved into Computer Reservation System (CRS). A CRS

is used for the reservations of a particular airline and interfaces with a Global

Distributed System (GDS) which supports travel agencies and other distribution

channels in making reservations for most major airlines in a single system.

Airline Reservations Systems contain airline schedules, fare tariffs, passenger

reservations and ticket records. An airline's direct distribution works within their

own reservation system, as well as pushing out information to the GDS. A second

type of direct distribution channels are consumers who use the internet or mobile

applications to make their own reservations. Travel agencies and other indirect

distribution channels access the same GDS as those accessed by the airlines'

reservation systems, and all messaging is transmitted by a standardized messaging

system that functions primarily on TTY messaging called SITA. Since airline

reservation systems are business critical applications, and their functionally quite

complex, the operation of an in-house airline reservation system is relatively

expensive.



PROBLEM DEFINITIONS

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.

Technichal System

Need of Airlines system:

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

1) Faster System

2) Accuracy

3) Reliability

4) Informative

5) Reservations and cancellations from anywhere to any place

TOOLS

FRONT END: VISUAL BASIC 6.0

Visual Basic is an ideal window programming language for developing sophisticated

applications that has been developed at Microsoft Corporation. It makes use of

Graphical User Interface (GUI) for creating Robust and powerful applications and it

includes all the necessary extensions required to produce Windows program.

It is an object oriented event driven programming language.

It means all activities are dependent upon the objectives like Command button,Text box, Label and also dependent upon the events like Click, Change, Key pres,

Key down etc.

There are two types of events:

User events

The action or event which is taken or performed by the user

System events

The action or event which is taken or performed by the system

Visual basic applications are very popular as front end to many client server

database systems like SQL server, Oracle etc. the basic idea behind using visual

basic as front end it is easy to understand, easy to learn. The application we built in

visual basic is not limited to tools provided in the development environment

There are few external tools that can enrich the application. Microsoft visual basic

for windows comes in working model, a learning edition, a professional edition and

an enterprise edition.

The basic version learning edition is built primarily to creation to standalone

application and basic programming.

The professional edition provides developer with fullest of tools for developing

solution including ActiveX controls, the internet information, server application,

designer, integrated visual database tools and data environment.



Page12

BACK END: SQL

SQL is both an easy to understand language and a comprehensive tool for

managing data. Here are some of the major features of SQL and the market forcesthat have made it successful.

Vendor independence

Portability across computer systems

SQL standards

IBM endorsement and commitment (DB2)

Microsoft commitment (SQL server, ODBC, and ADO)

Relational foundation

High – level English – like structures Interactive, and adhoc queries

Programmatic database access

Multiple views of data

Complete database language

Dynamic data definition

Client/Server architecture

Enterprise application support

Extensibility and object technology

Internet database access

Java integration (JDBC)

Industry infrastructure

These are the reasons why SQL has emerged as the standard tool for managing

data on personal computers, minicomputers, and main frames.

SYSTEM ANALYSIS:

“System analysis is the term used to describe the process of collecting analyzing facts in

respect of existing operation of the situation, prevailing so that an effective computerized

system may be designed and implemented if proved feasible” .

“ System analysis can be viewed as the most recent and perhaps the most comprehensive

technique for solving computer problems” .

“ System analysis may be considered as an inter phase between the actual problem and the

computer: a kind of midwife to all computer applications. Before a computer can perform,

it is necessary to investigate and analyses the system. The individuals who perform the

systems investigation, as distinct from those involved in the detailed, computer

programming are called System Analyst.”



Page15

This was the most important phase of my project life cycle. It had connected my

maximum time. The block diagram given bellow depicts various facts which were

understood by one during the analysis phase.

In that phase initially I had observed the system by visiting the local airport

(domestic terminal) and a few airline reservation agencies.

The above block diagram is an implementation of this observation.

In the next phase I had various queries in my mind, which I tried to ask from

appropriate authorities. A sample of my quires is enclosed as Annex 1.

Q.1 Tick mark the features that have to be included in the new system?

Enquiry

Reservation

Cancellation

Other specify

Q2. Tick mark that the system should be?

Multi-user

Single user

Q3. Tick marks the total time required for the implementation of the project?

3 months

6 months

9 months

Others specify

Q4. Tick mark the reports to be incorporated?

List of all passenger

List of all flights

List of passenger(date wise)

List of passenger(flight wise)

After getting solutions for my queries I started studying database structure used in

the existing system. In this connection I came to know about various master files

known as:

Various categories of flight code are displayed here CD455, IC548, IC7896, IC567,

CD445. Flight schedule - GAU to DEL 12.33 pm to 2.33 pm.

In this process I had further visited the airport again in order to INTERVIEW people

to know more about the system. The main purpose was to analyses the method of

calculating daily the income in reservation cost, generation methods, and few

other concerns like: Duty schedule.



Page19

SYSTEM DESIGN:

“System analysis also embraces system design, which is an activity concerned with the design of a

computerized application based on the facts disclosed during the analysis stage. Both activities are

carried out by the same person who is known as System Analyst.

System design: up to the time of the systems proposal, analysts have concerned themselves with the

local design of the system.”



Page20

In this phase initially I had designed E-R diagrams of the processes, in order to

identify various entities and relationship set, entity set, attributers, link attributes.

After this step we tried to design the database for the new system and normalized

it. The tables motivated in data dictionaries enclosed as Annex II is an outcome of

this step.

The symbols of entities are shown below:

INPUT SCREENS

As a last step in design phase I had designed various Input and Output inter phase

screens. The sample format of this screens is enclosed in Annex III.

This is a picture of the Main Menu

In this picture there are three parts called; Master file, Ticket, Report.

When we click on Master File, it shows six forms called: Custodial, Concession,

Flight info, Fleet info, Fare and Payment.

When we click on one of these then the other form open.Now we open each file one by one.



Page29

This is a form of Customer Detail

In this form we enter customer detail. When we enter a new name and click the add button

and then update, the files get automatically updated. This comes under Master File.

If we click on the button called ‘First’ it takes us back to the first record and similarly thebutton called ‘Last’ takes us to the last record.

If we click on the ‘Previous’ button it takes us to the previous record and if we click on the

‘Next’ button it takes us to the next record



Page30

This is a form of Concession

In this form there are several concession types which are give beow: -

1. Student 2. Senior citizen3. Cancer patient4. Blind passenger

5. Armed force6. Youth fare 7. Locomotor

When we click on any one of them, the relevant conditions are open

In this form when we click on the locomotor category it shows its conditions: -

code …………………...7

class …………………...ecnomic

discount ………….........50%

v_o_t ………………...…1 year

baggage allowance …..20kg fare basis ………………service concerned



Page31

This is a form of Flight Information

In this form we watch the flight information. It has several fields some of them are: -

Flight name

Flight code

Class code Class name

Total seat number

In this form we enter the flight detail. If we want to enter a new flight, we click the ‘add’

button and then update it. This comes under master file.

Here the button ‘First’ works to show the first record, the ‘Next’ button works to show the

next record and the ‘Previous’ button works to show the previous record.



Page32

This is a form of Fleet Information

Fleet Information is a special type of form. In this form there are some fields included.

In fleet information there are basic types of flights:

737 – 400

737 – 500 Club pre capacity ………………………….00 737 – 700 Economic capacity ……………………….62

737 – 800 Engine type ………………………………….PW127F

737.900 Cruise speed …………………………………511km/hr

Air length …………………………………………………………….27.17N

Wing spam …………………………………………………………..27.0N



Page33

This is a form of Route Basis Fare

In this fare form there are various fields which are mentioned below:

Route

S_place

D_place Via

D_time

A_time

Stoppage

Flight_code

Class_code

Fare

When we enter a new fare and click the ‘Add’ button and then update, it gets

automatically updated. This comes under the Master File. In this form the ‘First’

button works to show the first record, the ‘Next’ button works to show the nextrecord and the ‘Previous’ button shows the previous record.



Page34

This is a form of Reservation

This is a reservation form or ticket. The PNR numbers are generated automatically.

When we click at passenger ‘Age’ then fare is coming by the route based. When we

click the ‘Total’ button then the total fare is shown. When we click on the ‘Print’

command button then the ticket is printed. And when we click on the ‘Exit’ buttonthe form is closed.



Page35

This is an Enquiry form

If anyone wants to confirm his seat reservation, then an enquiry form is opened. In the form

we need to fill the value of ticket and click on the ‘Confirm’ button. If it is confirmed then it

shows the value of all the concerning data. And if not confirmed then it shows ‘Not

confirmed’.



Page36

This is a Cancellation form

When a person comes to cancel his ticket then, in the form we fill the passenger

code and click the ‘Show’ button. The system will show the value of data and the

amount to refund. Then by clicking on the ‘Cancel’ command the record is

automatically deleted.

TESTING



Page65

WHITE BOX TESTING

White box testing, sometimes called glass – box testing, is a test case design

method that uses the control structure of the procedural design to derive test

cases.

This testing technique takes into account the internal structure of the system or

component. The entire source code of the system must be available. This

technique is known as white box testing because the complete internal structure

and working of the code is available.

Using white – box testing methods, the software engineer can derive test cases

that:

1) Guarantee that all independent paths within a module have been exercised

at least once,

2) Exercise all logical decision on their true and false sides,

3) Executes all loops at their boundaries and within their operational bounds,

and

4) Exercise internal data structures to ensure their validity.

White box testing helps to:

Traverse complicated loop structures

Cover common data areas

Cover control structures and sub – routines

Evaluate different execution paths

Test the module and integration of many modules

Discover logical errors, if any

Helps to understand the code

Why the white box testing is used to test conformance to requirements?

Logical errors and incorrect assumptions most likely to be made when

coding for “special cases”. Need to ensure these execution paths are tested.

May find assumptions about execution paths incorrect, and so make design

errors. White box testing can find these errors.

Typographical errors are random. Just as likely to be on an obscure logical

path as on a main stream path.



Page67

TESTING, VALIDATION AND DEBBUGING

In this phase I tried to check all the modules separately for their proper formatting.

After this step I had performed a unit test to check the functionality of the whole

system.

Further I had come to know to add certain validation in project as given bellow:

1) Table name- Customer information

Field name –Customer nameData type -Text.

When we enter a number in the form it shows an error message. Because it

is not a number, it is a character. So it shows a wrong value.

2) Table name _Customer information

Field name - Departure time, Arrival time, Data type - Date/Time.

When we enter 12.33 then it automatically shows 12.33pm.

When we enter 11.33 then it automatically shows 11.33am.

3) Table name –Flight information

Field name - Flight-code

Data type - number

If we put any other value or character, then it asks for validity check.



Page68

IMPLEMENTATION

For the implementation of my project the hardware and software requirements are given below:

HARDWARE:

1 GHz Processor

25 MB RAM

100 MB Disk Space

SOFTWARE:

XP/VISTA/7

MS – ACCESS

MS – EXCEL

MS – WORD



Page69

CONCLUSION

Though this system still contains a lot of scope for improvement, still its overall

look and feel gives us a rough picture of on existing automation system.

I have used MS-Access as a backend but it has a limitation of 1 GB size. If the data

size exceeds the size limit, then some other databases such as SQL server or Oracle

can be used with ODBC to break this barrier.
