OBJECTIVES
Airways has a number of reservation offices in each city where the flights operate. Each
reservation office has a number of reservation counters to handle reservations and
cancellations. Each counter has a counter assistant who is responsible for making
reservations or cancellations. The main objective of this project to performed
reservation, cancellation and report.
In concerned to reservations, the following activities are done.
Accepts the date, sector, and class of travel from the person and checks for the
availability of a seat in the Reservation file.
Confirms the details with the prospective passenger and accepts the remaining
details.
Update the seat availability status in the reservation file and adds the passenger
details to the file. The passenger is assigned a unique Passenger Name Request
(PNR) number,
Collects the fare amount.
Update the Daily Collection file with the fare amount.
In concerned to cancellation, the following activities is done
Retrieves the details from the file using the PNR number.
Verifies the details of the ticket and computes the refund amount.
Updates the seat availability status in the reservations file and marks the
corresponding details of the file.
Makes the refund and prints the refund receipt.
Files the receipt along with the signature of the passenger .
Updates the Daily Collection file.

SYSTEM ANALYSIS
Analysis is a detailed study of the various operations performed by a system and
their relation within and outside the system. A key question is what must be done to
solve the problem. One aspect of the analysis defining the boundaries of the system and
determining whether or not a candidate system should consider other related system.
During analysis data are collected on the available files decision points and transaction
handled by the parent system. Some logical system models and tools are used in the
analysis. Data flow diagrams, interviews, onsite observation and questionnaires are
examples, the interview is commonly used in analysis. It requires special skill and
sensitivity to the subject being interview bias in data collection and interpretation can be
problem.
Training experience and common sense are required for Collections of the information
are needed to do analysis. Once analysis is completed, the analyst has firm
understanding of what is to be done. The next step is to decide how the problem might be
solved. Thus in system design, we be move from the logical to the physical aspects of
the life cycle.
The Initial Investigation and Identification of need :
The most critical phase of managing system projects is planning to launch a system
investigation, we need plan detailing the steps to be taken, the people to be questioned
and they out come expected. The initial investigation has the objective of determining
whether the users request has potential merit. The major steps are defining user
requirements. When the initial investigation is completed. The user receives a proposal
summarizing the finding the recommendation of the analyst.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 11
A key part of feasibility analysis is gathering information about the present system. The analyst knows what information to gather, where to find it, how to collect it and what to make of it. The proper use of tools for gathering information is the key to successful analysis. The tools are the traditional interview, questionnaire, and on-site observation. We need to know, for example how to structure an interview, what makes up a questionnaire, and what to look for on-site observations. These tools when learned help analysis assess the effectiveness of the present system and provide the groundwork for recommending a candidate system.
Identification of need
The system need accomplish the following functions:
The system should allow the counter assistants to handle ticketing and refunds.
While accepting reservation data, all necessary validations should be performed.
For example, the system should check whether a flight operates on the date of
travel specified by the passenger. It should also check the seat availability status.
After all data has accepted, the system should print the ticket. It should also store
the passenger details, update the daily collections, and update the seat plan.
In case of cancellation, the system should accept the PNR number from the user,
validate the PNR number and update the cancellation flag for the passenger. The
system should then print the refund receipt. It should also update the daily
collections to reflect the refund amount. The status of overbooked and wait-listed
tickets should be changed whenever a confirmed ticket is cancelled.
The system should generate the following reports:
1. Confirmed passenger list
2. Waiting list
3. Daily collection report
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 12
In addition, the new system should provide facilitate passengers to perform the following
tasks:
Check the waiting list status.
View rates for different sectors.
View flight schedules for a specific period. This module should be developed as
an affiliate program that can be easily integrated with various Web sites.

FEASIBILITY STUDY
The main objective of the preliminary analysis is to identify the problem, evaluate the system concept of feasibility, and perform the economic and technical analyses perform the cost benefit analysis. After the clarification analysis the solution proposed it is checked that it is practical to implement that solution. This is done through the feasibility study. It is checked for various aspects whether the proposed solution is technically or economically feasible or not. On the basis if which it has been categorized into four classes viz
1.) Technical
2.) Economic
3.) Operational
The outcome of the preliminary analysis should be clear so that an alternate way to do the job can be found out?
1.Technical Feasibility :
During the technical feasibility studies following issues are taken into consideration
1. Whether the required technology is available or not?
2. Required resources are available or not? (Manpower, programmer, software and
hardware etc)
Once the technical feasibility is established, it is important to consider the monetary factors also. Since it might happen that developing a particular system may be technically possible but it may be require huge investments and benefits may be less. For evaluating this, economic feasibility of the proposed system is carried out.
As in our proposed system our team has technically trained manpower with knowledge of developing the system. We are going to use web technology in our system, which is readily available. Software to be used is also available easily.
So technically the project is feasible.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 14
2. Economic Feasibility:
For any system if the expected benefits equal or exceed the expected costs, the system can be judged to be economically feasible. In economic feasibility, cost benefit analysis is done in which expected costs and benefits are evaluated.
Economic analysis is used for evaluating the effectiveness of the proposed system. In economic feasibility, the most important is cost benefit analysis. As the name suggests, it is an analysis of the cost to be incurred in the system and benefits derivable out of the system.
As in our institute the hardware and software required for this type of system is already available so economically our project is feasible.
3. Operational Feasibility
The staff of the company (client) is used to the computer. They will only be given
training about the proposed system to make efficient use of it.
This feasibility study is carried out by a small group of people who are familiar with
information system techniques, who understand the part of the system that are
relevant to the project and are skilled in system analysis and design process.
Considering the above three feasibility we can say that the system is feasible and
ahead for analysis of the system.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 15
In the software principle we are using the incremental model (evolutionary software
process model). The incremental model combines elements of the linear sequential
model with the iterative philosophy of prototyping.
The linear sequential model suggests a systemic, sequential approach to software
development that begins at the system level and progress through analysis, design,
coding and module testing, delivery and maintenance.
ANALYSIS:
In this phase we will gathered all the information about the organization queries and
analysis requirement for both the system and software documented and reviewed
with the users.
DESIGN:
After analysis we documented all the Interface representations, and algorithm details.
CODING AND MODULE TESTING:
After designing, coding plays major role in software development process. We are
using JAVA(JSP) in front end, ORACLE in the back end for coding
Individual modules developed in this phase is also tested before being delivered to the
program testing phase.
PROGRAM TESTING:
Once the module has been developed. Program testing begins We will provide some
other users for testing for few days, and all problems and errors, which overcome
during testing, will be pointed out. The user requirement will be also kept in mind and
then delivery process begins.
DELIVERY: “AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM”

Page 16
SOFTWARE ENGINEERING PARADISM
Once the system passes all the tests, it is delivered to the customer and enters the
maintenance phase.
MAINTENANCE:
Software will undoubtedly undergo changes because errors have been encountered. So
keeping requirement and testing in mind, we will make some necessary changes.

PROJECT ANALYSIS
(OOPS – Object Oriented Programming System)
Object Oriented Programming is a method of programming that seeks to mimic the way
we form models of the world. To cope with the complexities of life, we have evolved a
wonderful capacity to generalize, classify and generate abstractions. Almost every noun
in our vocabulary represents a class of objects sharing some set of attributes or
behavioral traits.
The entire basis of Object Oriented Programming, infect is defining the Object in Object
Oriented Programming. Object is a unit that combines both code and data together. And
an object is an instance of a class. Class is a type of data structure defined to hold both
data and the code functions.
Object Oriented Programming also allows you to design and implement your application
more quickly than traditional approaches. Object Oriented Programming also makes
code easier to maintain so that you can refine the implementation without causing major
problems.
Since object-oriented programming was fundamental to the development of C++, it
is important to define precisely what object-oriented programming is. Object-oriented
programming has taken the best ideas of structured programming and has combined
them with several powerful concepts that allow you to organize your programs more
effectively. In general, when programming in an object-oriented fashion, you decompose
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 20
a problem into its constituent parts. Each component becomes a self-contained object
that contains its own instructions and data related to that object. Through this process,
complexity is reduced and you can manage larger programs.
Encapsulation
As you probably know, all programs are composed of two fundamental elements:
program statements (code) and data. Code is that part of a program that performs
actions, and data is the information affected by those actions. Encapsulation is a
programming mechanism that binds together code and the data it manipulates,
and that keeps both safe from outside interference and misuse.
In an object-oriented language, code and data may be bound together in such a way
that a self-contained black box is created. Within the box are all necessary data and
code. When code and data are linked together in this fashion, an object is created.
In other words, an object is the device that supports encapsulation.
Within an object, the code, data, or both may be private to that object or public.
Private code or data is known to, and accessible only by, another part of the object.
That is, private code or data may not be accessed by a piece of the program that exists
outside the object. When code or data is public, other parts of your program may access
it, even though it is defined within an object. Typically, the public parts of an object
are used to provide a controlled interface to the private elements of the object.
Polymorphism
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 21
Polymorphism (from the Greek, meaning “many forms”) is the quality that allows one
interface to be used for a general class of actions. The specific action is determined by
the exact nature of the situation. A simple example of polymorphism is found in the
Steering wheel of an automobile. The steering wheel (i.e., the interface) is the same no
matter what type of actual steering mechanism is used. That is, the steering wheel works
the same whether your car has manual steering, power steering, or rack-and-pinion
steering. Therefore, once you know how to operate the steering wheel, you can drive
any type of car. The same principle can also apply to programming. For example,
consider
a stack (which is a first-in, last-out list). You might have a program that requires three
different types of stacks. One stack is used for integer values, one for floating-point
values, and one for characters. In this case, the algorithm that implements each stack
is the same, even though the data being stored differs. In a non-object-oriented language,
you would be required to create three different sets of stack routines, calling each set
by a different name, with each set having its own interface. However, because of
polymorphism, in C++ you can create one general set of stack routines (one interface)
that works for all three specific situations. This way, once you know how to use one
stack, you can use them all.
More generally, the concept of polymorphism is often expressed by the phrase
“one interface, multiple methods.” This means that it is possible to design a generic
interface to a group of related activities. Polymorphism helps reduce complexity by
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 22
allowing the same interface to be used to specify a general class of action. It is the
compiler’s job to select the specific action (i.e., method) as it applies to each situation.
You, the programmer, don’t need to do this selection manually. You need only
remember and utilize the general interface.
The first object-oriented programming languages were interpreters, so polymorphism
was, of course, supported at run time. However, C++ is a compiled language. Therefore,
in C++, both run-time and compile-time polymorphism are supported.
Inheritance
Inheritance is the process by which one object can acquire the properties of another
object. The reason this is important is that it supports the concept of hierarchical
classification. If you think about it, most knowledge is made manageable by
hierarchical (i.e., top-down) classifications. For example, a Red Delicious apple is part
of the classification apple, which in turn is part of the fruit class, which is under the
larger class food. That is, the food class possesses certain qualities (edible, nutritious,
etc.) that also apply, logically, to its fruit subclass. In addition to these qualities, the
fruit class has specific characteristics (juicy, sweet, etc.) that distinguish it from other
food. The apple class defines those qualities specific to an apple (grows on trees, not
tropical, etc.). A Red Delicious apple would, in turn, inherit all the qualities of all
preceding classes, and would define only those qualities that make it unique.
Without the use of hierarchies, each object would have to explicitly define all of
its characteristics. However, using inheritance, an object needs to define only those
qualities that make it unique within its class. It can inherit its general attributes from “AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM”
Enrollment No.
Page 23
its parent. Thus, it is the inheritance mechanism that makes it possible for one object
to be a specific instance of a more general case.
C++ Implements OOP
As you will see as you progress through this book, many of the features of C++ exist
to provide support for encapsulation, polymorphism, and inheritance. Remember,
however, that you can use C++ to write any type of program, using any type of
approach. The fact that C++ supports object-oriented programming does not mean
that you can only write object-oriented programs. As with its predecessor, C, one of
C++’s strongest advantages is its flexibility.

RISK ANALYSIS
Project Risk: It identify potential budgetary, schedule, personnel, resource,
customer, and requirements problems and their impact on software. All the
above factors are analyzed, customer requirements are analyzed properly.
Technical Risk: It identifies potential design, implementation, interface,
verification, and maintenance problems. All the above factors have been
analyzed.
Business Risk: (1) Software is developed keeping in mind that there is demand in
custom, so that to avoid the market risk. (2) Software is designed to fit into the
overall business strategy for the custom department, to avoid the strategic risk.
(3) The software is easily understandable by the sales person’s team, so that
they could know much about the product working and sell in the market. (4) It
has the strong management support, and not likely to change in the management
people to avoid the management risk. (5) Software fits the budget and there is no
budget risk.

OJBECT ORIENTED DEVELOPMENT
An object-oriented system draws upon class definitions that are derived from the
analysis model. Some of these definitions will have to be built from scratch, but
many others may be reused it appropriate design patterns are recognized. Object
Oriented Design establishes a design blueprint that enables a software engineer to
define the Object Oriented architecture in a manner that maximized reuse, thereby
improving development speed and end-product quality.
The four layers of the Object Oriented design are:
The subsystem layer: It represents each of the subsystems that enable the software
to achieve its customer-defined requirements and to implement the technical
infrastructure that supports customer requirements, in the custom department.
The class and object layer: It contains the class hierarchies that enable the system
to be created using generalizations and increasingly more targeted specializations.
The message layer: It contains the design details that enable each object to
communicate with its collaborators. This layer establishes the external and inters
interfaces for the software.
The responsibilities layer: It contains the data structure and algorithmic design for
all attributes and operations for each object.

FEASIBILITY STUDY
Steps in feasibility analysis
Eight steps are involved in the feasibility analysis. They are :
1. Form a project team and appoint a project leader.
2. Prepare system flowcharts.
3. Enumerate potential proposed systems.
4. Define and identify characteristics of proposed system.
5. Determine and evaluate performance and cost effectiveness of each
proposed system.
6. Weight system performance and cost data.
7. Select the best proposed system.
8. Prepare and report final project directive to management
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 28
TYPE OF FEASIBILITIES
1. Economic Feasibility
Economic analysis is the most frequently used technique for evaluating the
effectiveness of a proposed system. More commonly known as cost / benefit
analysis; in this procedure we determine the benefits and savings that are
expected from a proposed system and compare them with costs. We found the
benefits outweigh the costs; we take a decision to design and implement the
new proposed system.
2. Technical Feasibility
This is concerned with specifying equipment and software that will
successfully satisfy the user requirement. The technical needs of the system
may vary considerably, but might include:
· The facility to produce outputs in a given time.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 29
· Response time under certain conditions.
· Ability to process a certain volume of transaction at a particular speed.
· Facility to communicate data to distant location.
After examining technical feasibility, we give more importance to the
configuration of the system than the actual make of hardware. The
configuration gives the complete picture about the system's requirements:
Ten to twelve workstations are required, these units should be interconnected
through LAN so that they could operate and communicate smoothly. They
should have enough speeds of input and output to achieve a particular quality
of printing.
3. Operational Feasibility
It is mainly related to human organizational and political aspects. The points
to be considered are:
· what changes will be brought with the system?
· what organizational structures are disturbed?
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 30
· what new skills will be required? Do the existing staff members have these
skills?
· If not, can they be trained in due course of time?
Generally project will not be rejected simply because of operational
infeasibility but such considerations are likely to critically affect the nature
and scope of the eventual recommendations.
For operational feasibility study we appointed a small group of people who
are familiar with information system techniques, who understand the parts of
the business that are relevant to the project and are skilled in system analysis
and design process.
4. Social feasibility
Social feasibility is a determination of whether a proposed project will be
acceptable to the people or not. This determination typically examines the
probability of the project being accepted by the group directly affected by the
proposed system change.
5. Management feasibility
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 31
It is a determination of whether a proposed project will be acceptable to
management. If management does not accept a project or gives a negligible
support to it, the analyst will tend to view the project as a non-feasible one.
6. Legal feasibility
Legal feasibility is a determination of whether a proposed project infringes on
known Acts, Statutes, as well as any pending legislation. Although in some
instances the project might appear sound, on closer investigation it may be
found to infringe on several legal areas.
7. Time feasibility
Time feasibility is a determination of whether a proposed project can be
implemented fully within a stipulated time frame. If a project takes too much
time it is likely to be rejected.

SYSTEM DESIGN
Introduction
System design provides the understandings and procedural details necessary for
implementing the system recommended in the system study. Emphasis is on the
translating the performance requirements into design specifications. The design has is a
transition from a user-oriented document (System proposal) to a document oriented to
the programmers or database personnel.
System design goes through two phases of development:
1) Logical Design
2) Physical Design
A data flow diagram shows the logical flow of the system. For a system it
describes the input (source), output (destination), FILE (data stores) and procedures (data
flows) all in a format that meets the user’s requirement. When analysis prepare the
logical system design, they specify the user needs at a level of detail that virtually
determines the information flow into an out of the system and the required data
resources. The logical design also specifies input forms and screen layouts.
The activities following logical design are the procedure followed in the physical
design e.g., producing programs, software, file and a working system. Design
specifications instruct the user about what the system should do.
Logical and Output Design:
The logical design of an information system is analogous to an engineering blue
print of an automobile. It shows the major features and how they are related to one “AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM”
Enrollment No.
Page 33
another. The detailed specification for the new system was drawn on the bases of user’s
requirement data. The outputs inputs and databases are designed in this phase.
Output design is one of the most important features of the information system.
When the output is not of good quality the users will be averse to use the newly designed
system and may not use the system. There are many types of output, all of which can be
either highly useful or can be critical to the users, depending on the manner and degree
to which they are used.
Outputs from computer system are required primarily to communicate the results
of processing to users; they are also used to provide a permanent hard copy of these
results for later consultation. Various types of outputs required can be listed as below:
External Outputs, whose destination is outside the organization
Internal outputs, whose destination is with the organization
Operational outputs, whose use is purely with in the computer department
e.g., program-listing etc.
Interactive outputs, which involve the user is communicating directly with
the computer, It is particularly important to consider human factor when
designing computer outputs. End user must find outputs easy to use and
useful to their jobs, without quality output, user may find the entire system
unnecessary and avoid using it. The term “Output” in any information system
may apply to either printer or displayed information. During the designing
the output for this system, it was taken into consideration, whether the
information to be presented in the form of query of report or to create
documents etc.
Other important factors that were taken into consideration are:
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 34
The End user, who will use the output.
The actual usage of the planned information
The information that is necessary for presentation
When and how often output and their format is needed. While designing
output for project based Attendance Compilation System, the following
aspects of outputs designing were taken into consideration.
The outputs (i.e., well formatted table outputs in the screen itself) designed
are simple to read and interpret.
Format of each output was another important point taken into consideration.
Output media, for each output appropriate media is decided whether it will be
displayed on screen or will be taken to printer or both.
Other output design related specifications, i.e., how frequently the outputs
will be generated, how many pages or sheets approximately it will keep up,
what is its planned use and output distribution to users are also taken into
account.
These were a few major designing issues, which were taken into consideration,
while deciding the output specifications for the system. As direct beneficiary of reports is
the user community, they were consulted constantly at every level. Formats and screen
design for various reports were identified, taking into account the user requirements.
Before finalising these were given to users for any improvement and suggestions. End
users issues taken into consideration were Readability, Relevance and Acceptability.
Once all the output reports to be generated by HARS system were identified, they
were given to users for their acceptance. For prototyping various outputs, final outputs
models were created with dummy data, before they were finalized.

Output Sources:
Output contents originate from these sources:
Retrieval from a data source.
Transmission from a process or system activity.
Directly from an input source.
The information produced in an output can be presented as
Tabular contents
Graphic format

Data items
The name given to each data item should be recorded and its characteristics described
clearly in a standard form:
Whether alphanumeric or numeric
Legitimate and specific range of characteristics
Number of characters
Positions of decimal point, arithmetic design, etc.,
Input Design:
The input design is the link that ties the information system into the user’s world.
Input specifications describe the manner in which data enters the system for processing.
Input design features can ensure the reliability of the system and produce results from
accurate data, or they can result in the production of erroneous information.
Input Design consists of
developing specifications and procedures for data preparation
Steps necessary to put data into a usable form for processing.
Data entry, the activity of putting data into the computer processing.
Objectives of Input design
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 37
Five objectives of design input focus on
Controlling the amount of input required
Avoid delay
Avoiding errors in data
Avoiding extra steps.
Keeping the process simple.
Input stages several activities have to be carried out as part of the overall input
process. They include some or all of the following.
Data recording (i.e., collection of data)
Data encapsulation (i.e., transfer of data)
Data conversion (i., e.controlling the flow of data)
Data transmission (i.e., transporting the data)
Data validation (i.e., checking the input data)
Data correction (i.e., correcting the errors)
Input Performa were designed, after a careful discussion with users. It was
attempted to cover all user requirements. Designed Performa were given to user for any
suggestion and final approval.
Various data items were identified and wherever necessary were recorded. As the
data concerning of HARS is voluminous in nature and number of case will grow
dynamically in future, proper care was taken for accuracy and consistency of data.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 38
Input designs are aimed at reducing the chances of mistakes of errors. As the
human beings are prone to errors there is always a possibility of occurrence of chance of
errors. Adequate validation checks are incorporated to ensure error free data storage.
Some of the data validation checks applied are as following:
Redundancy of data is checked. It means the records of primary key do not
occur twice.
Primary key field of any table must not be left blank.
Wherever items are coded, input code is checked for it’s validly with respect
to several checks.
Utmost care has been taken to incorporate the validation at each stage of the
system. E.g. when entering records into employee information table for
employee, it is checked that whether the corresponding employee exists in
the employee information table etc.,
Enough messages and dialogue boxes are provided while design screen, which does guide user at the time of any errors, or at time of entry. This feature provides a user-friendly interface to native users. It can be emphasized that input deigns of HARS system is so designed that it ensures easy and error free data entry mechanism. Once one is sure of input data the output formatting becomes a routine work.

Airways has a number of reservation offices in each city where the flights operate. Each
reservation office has a number of reservation counters to handle reservations and
cancellations. Each counter has a counter assistant who is responsible for making
reservations or cancellations. The procedure followed for performing reservations and
cancellations is given bellow.
Reservation
Reservations for a flight commence 30 days before the date of the flight. The procedure
for making reservations is given below. The procedure described below deals with the
provisional reservations the can be made through telephone conversation.
On receiving request for reservation from a person, the counter assistant performs the
following activities:
Accepts the date, sector, and class of travel from the person and checks for the
availability of a seat on the requested date. The details about the availability seats
and the seat plan are kept in the Reservation file.
Confirms the details with the prospective passenger and accepts the remaining
details. These details include the preferences such as a window or an aisle seat, a
smoking or a non-smoking zone, meal preferences such as vegetarian or non-
vegetarian, and special service requests (SSR), such as dietary and medical
considerations.
Update the seat availability status in the reservation file and adds the passenger
details to the file. The passenger is assigned a unique Passenger Name Request
(PNR) number, which is used to access ticket details for queries and cancellation.
Collects the fare amount.
Prints the ticket and gives it to the passenger.
Update the Daily Collection file with the fare amount.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 40
Horizon Airways also provides for overbooked and wait-listed tickets for the economy
class. Overbooking is allowed for 10 seats per flight. For example, if the capacity of an
aircraft is 340 seats, booking are made for 350 seats, that is, 340 seats + 10 overbooked
tickets. If the number of bookings exceeds the capacity and overbooking, a wait-listed
ticket is issued to the passenger with his or her consent. An overbooked or wait-listed
passenger is accommodated on the flight depending on the availability of a seat when the
passenger checks in. A passenger who cannot be accommodated on a flight is given full
refund.
Cancellation
On receiving a cancellation request from a passenger the counter assistant performs the
following tasks:
Retrieves the details from the file using the PNR number.
Verifies the details of the ticket and computes the refund amount.
Updates the seat availability status in the reservations file and marks the
corresponding details of the file.
Makes the refund and prints the refund receipt.
Files the receipt along with the signature of the passenger.
Updates the Daily Collection file.
The amount of refund is calculated based on the ticket status and the date cancellation. If the ticket is wait-listed or overbooked, full amount is refunded.

SOFTWARE TESTING & IMPLIMENTATION:
SOFTWARE TESTING:
The purpose of this document is to cover testing of Horizon Airways project from all
aspects i.e. from module wide testing to system integration testing.
Software testing is a process of executing a program with objective of finding an
error. Software quality should be a primary concern in software development efforts.
Software testing and evaluation are traditional method of checking software quality. It
consists of putting together various coded pieces of a design, testing them and correcting
the parts of the code or the design that is not correct. At this stage some errors are
introduced purposely to test whether the program will spot them.
Test summary document with test results (Quality Record) for each test case with
problems found during the test execution. After review of test summary document, it will
be decided if any test case is to be repeated or if the identified problem should be
converted into “a defect” to be fixed in subsequent release of product.
Data entry:
Is alphanumeric data entry properly echoed and input to the system?
Do graphical modes of data entry work properly?
Is invalid data properly recognized?
Are data input messages intelligible?
TESTING STRATEGIES:
A strategy for software testing may also be viewed in the context of spiral. Unit testing
begins at the vertex of the spiral and concentrates on each unit of the software as
implemented in source code. Testing progresses the moving outward along the spiral to
integrations testing. Where the focus is on design and the and the construction of the
software architecture. Taking another turn outward on the spiral, we encounter validation
testing, where requirements established as part of software requirements analysis are
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 100
validated against the software that has been constructed. Finally, arrive at system testing,
where the software and other system elements are tested as a whole. Here I will specify
each testing but the outcome of the testing and reports is not included because they are
very large and I have to give Project- Report in limited page.
Unit testing: In Unit testing module interface, local data structures. Boundary
conditions, independent paths, error handling paths are tested.
Module interface is tested to ensure that information properly flows into and our of the
program unit under test. The local data is structure is examined to ensure that data stored
temporarily maintained its integrity during all steps in an algorithm’s execution.
Boundary conditions are tested to ensure that the module operates properly at boundaries
established to limit or restrict processing. All independent paths through the control
structure are exercised to ensure that all statements in a module have been executed at
lest once. And finally, all error handling paths are tested.
Thus the unit testing is done after code development, reviewed, and verified for correct
syntax and in unit testing we execute each module one by one and prepare a report of
result.
Integration technique:
Integration testing is a systematic technique for constructing the program structure while
conducting tests to uncover errors associated with interfacing. The objective is to take
unit tested modules and build a program structure that has been dictated by design. Their
are three type of integration testing, each are discussed below.
TOP DOWN INTEGERATION:
This technique is an approach to construction of program structure. Modules are
integrated by moving downward through the control hierarchy, beginning with the main “AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM”
Enrollment No.
Page 101
control module. Modules subordinate to the main control module are incorporated into
the structure either into a depth-first or breadth first manner. I used depth-search for
testing which integrate all modules on a major control path of structure.
BOTTOM OF INTEGERATION:
This technique begins construction and testing with atomic modules. Because modules
are integrated from the bottom up, processing required for module subordinate to a given
level’s always available and the need for stubs are eliminated.
REGRESSION TESTING:
This technique is the activity that help to ensure that changes during the testing do not
introduce unintended behavior or additional errors.
Validation testing:
Validation succeeds when software functions in a manner that can be reasonably expected by the customer. There are two types of validation testing these are discussed below.
ALPHA TESTING:
The alpha tests are conducted at the developer’s site by a customer. The software is used in a natural setting with the developer. Alpha tests are conducted in a controlled environment.
BETA TESTING:
The beta tests are conducted at one or more customer sites by the end use of the
software. Unlike, the alpha testing, the developer is generally not present. Therefore, the
beta test is a “live” application of the software in an environment that cannot be
controlled by the developer. The customer records all problems that are encountered
during beta testing and reports these to the developer at regular intervals. As a results of
problems reported during beta test. The software developer makes modifications and
then prepares for release of the software product to the entire customer base.

Page 102
System testing:
It is a series of different test whose primary purpose is to fully exercise the computer-
based system. These are discussed below:
RECOVERY TESTING:
It the system tests that forces the software to fail in a variety of ways and verifies that
recovery is properly performed.
SECURITY TESTING:
It attempts to verify that protection mechanisms built into a system will in fact protect, it
from improper penetration.
STRESS TESTING:
It executes a system in a manner that demands resources in abnormal quantity,
Frequency, or volume.
PERFORMANCE TESTING:
It is designed to test run-time performance of software within the context of an integrated
system. It occurs throughout all steps in the testing process.

IMPLEMENTATION
IMPLEMENTATION PLAN:
Implementation follows the forms to the detailed design stage. This effect of the
user department and system designer in getting the new steps in operation.
The following steps are performed during implementation:
1) System Testing: It is tested and ensured that the different modules are working
correctly individually and as a whole.
2) Review and Maintenance: Once the system becomes operational, it would be
examined to see if it has met its objective.
The system is reviewed and maintained periodically for the following reasons:
To deal with unforeseen problems arising in the operation i.e. programs may need
to be dealt with unforeseen circumstances.
To confirm that the planning objects have been met and if not work to achieve so.
To ensure that the system is able to cope with changing requirements.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 105
IMPLEMNTATION PROCEDURE:
The users in the organization are familiar with the basics of computers but will not be aware
with working of the new system. A training program will be conducted for three days to guide
the user about the new system. After the completion of the training program actual
implementation will start as follows:-
A. Pilot run of system.
B. Parallel run of system.
C. Change over of the system.
Pilot Run of System:
In this phase historical data will be entered into the system as test data and the output of the
system will be checked against the historical reports.
Parallel Run of System:
In this phase both the systems will be run in parallel form for about two to three months and the
results of both will be checked manually. After the completion of the time period, system will be
handed over to the management.
Change Over of the System:
This is the last phase of the implementation procedure. In this phase all the data will be
entered into the system by the user and the management will discontinue the manual
system.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 106
SYSTEM SECURITY MEASURES
To do an adequate job on security, a systems analyst must analyze the risk, exposure, and costs
and specify measures such as passwords and encryption to provide protection. The backup
copies of software and recovery restart procedures must be available when needed.
This system will provide the facilities for both customer & operators on the same portal. So
security constraints must be applied carefully. A customer wouldn’t require to login into the
reservation system for reservation. He will simply view all the information on web. While a
counter assistant will require to have user ID & Password. After proper validation checking of
that operator he can make transactions. His total transaction details will also be recorded along
with his ID in a log Table, so that any misusage of the system can be prohibited.
System security refers to various validations on data in form of checks and controls to avoid the
system from failing. It is always important to ensure that only valid data is entered and only
valid operations are performed on the system. The system employs two types of checks and
controls:
Client Side Security
Various client side validations are used to ensure on the client side that only valid data is
entered. Client side validation saves server time and load to handle invalid data. Some
checks imposed are:
A JavaScript program is used to fill up date in the date fields only.
JavaScript is used to ensure that numeric field is filled with numeric data only.
Maximum lengths of the fields of the forms are appropriately defined.
Forms can not be submitted without filling up the mandatory data so that manual
mistakes of submitting empty fields that are mandatory can be sorted out at the client
side to save the server time and load.
“AIR LINES RESERVATION SYSTEM”“AIR LINES RESERVATION SYSTEM” Enrollment No.
Page 107
Tab-Indexes are set according to the need and taking into account the ease of user
while working with the system.
Server Side Security
Some checks can’t be applied at client side. Server side checks are necessary to save the
system from failing and intimating the user that some invalid operation has been
performed or the performed operation is restricted. Some of the server side checks
imposed are:
Server side constraint has been imposed to check for the validity of Primary key and
foreign key. A primary key value cannot be duplicated. Any attempt to duplicate the
primary key value results into a message intimating the user about that. Values
through the forms using foreign key can be updated only for the existing foreign key
values.
Exceptions are caught in the programs and are used constructively to avoid system
failure. User is intimated through appropriate messages about the successful
operations or exceptions occurring at server side.
Access permissions to various types of users are controlled according to the
organizational structure. Only permitted users can log on to the system and can have
access according to their category. User-name, passwords and permissions are
controlled on the server side.
PERT chart and GANTT chart

A PERT Chart is a network of boxes and arrows. To create PERT chart, first we
need to list all the activities required for completion of the project and estimate how long
each will take. Then we must determine the dependence of activities on each other. The
PERT chart gives a graphical representation of this information. PERT chart is always
used by the project manager to answer the questions like which all activities are
necessary or there in the project and how long each will take.
Here we are using boxes to represent the activities. The arrows are used to show the dependencies of activities on one another. The activity at the head of an arrow cannot start until the activity at the tail of the arrow is finished. The boxes in a PERT chart can be decorated with starting and ending dates for activities.
GANTT Chart:
GANTT charts are a project control technique that can be used for several
purposes, including scheduling, budgeting, and resource planning. A Gantt chart is a bar

chart, with each bar representing an activity. The bars are drawn against a time line.
The length of each bar is proportional to the length of time planned for the activity.
