INTRODUCTION

Proposed “Railway Reservation System” is developed for to automate the railway

reservation system. It includes modules required to successfully operate railway reversion

process smoothly. It has train master to add modify train information, Train schedule to enter

train journey details include all the station name, arrival time and departure time. It includes

automatic fare calculation as per the distance between two stations.

Reservation module consist of automatic seat no and coach no allocation system. Daily

schedule for updation of not confirm seat and coach no. All master like train master, train

schedule, reservation fees, cancellation fees charges can be modified individually from front

end and changes reflect in all modules immediately.

Therefore proposed “Railway Reservation System” has been designed to automate the

process of railway for ticket reservation and back office activities. System can make the daily

activities efficient and providing the fast response.

Railway Reservation System – Modules

Security module - Security modules include security features like user management and application level password management.

Maintain user master- Each user identified by the user name and user type. Only

admin user can create, edit user information.

Password must be 6 characters long.

Password must be alpha numeric.

While creating user system assign default password for the user, user must change

default password for first time login.

All login time stamp stored in the system for security audit.

7

Access level and roles and privileges are set for different type of users.

Master Management module - Master management module includes following sub modules.

Station Master – Every station is uniquely identified by system generated Station ID.

It also includes station code, station name and railway division name.

Train Master – Every train uniquely identified by train no, it includes train name,

train schedule which days of the week train will run. No of coaches available for 3 tier

AC, First Class, Slipper Class etc.

Train Schedule – It includes train journey details from start station to end station, all

in between station, distances between 2 station, arrival and departure time.

Fare Rule – It help to calculate fare by distance, support different type of fare

calculation for different class like AC1, AC3 etc.

Cancellation Fees Rule - It provide the master data for all ticket cancellation fees

calculation.

Reservation and Super Fast Fees – It provide the master data for all ticket

cancellation fees calculation.

Transaction Module - Transaction module includes following sub modules.

Reservation – This module used to make reservation, it asks for input data like train

no, journey date, from station code, end station code. System has powerful validation

rule to check validation like journey date must be greeter than system date, journey

date must be within 90 days. Train should run for the selected day. Check for from

station and to station. Seat availability, While saving the record system generate PRN

no, seat no and coach no. Before save the system ask for final confirmation. System

automatically calculates the fare and save the details.

Cancellation – For cancellation of ticket it ask for PRN no, after entering the correct

PRN no system check for validity of the PRN no, whether it already cancelled,

journey date already expired. I it validate system display all the details of the

reservation. System automatically calculates the cancellation fees from the

cancellation rule master. Before save the record system ask for the confirmation.

8

Update Seat no for unconfirmed passenger – It is schedule activity, system query

for all cancelled ticket for particular journey date and allocates all vacant seat to

unconfirmed passenger.

Daily Cash Transaction – It shows daily transaction, like how much money received

and how much money refund. All data can be exported to MS Excel for review and

save in file system.

Query Module - A powerful query module give on screen information for particular PRN NO, it shows all the reservation details and cancellation details, include current status for the seat no, coach no.

SYSTEM ANALYSIS

Introduction to System Analysis

System analysis is a process of gathering and interpreting

facts, diagnosing problems and the information to recommend improvements on the

system. It is a problem solving activity that requires intensive communication

between the system users and system developers. System analysis or study is an

important phase of any system development process. The system is studied to the

minutest detail and analyzed. The system analyst plays the role of the interrogator and

dwells deep into the working of the present system. The system is viewed as a whole

and the input to the system are identified. The outputs from the organizations are

traced to the various processes. System analysis is concerned with becoming aware of

the problem, identifying the relevant and decisional variables, analyzing and

synthesizing the various factors and determining an optimal or at least a satisfactory

solution or program of action.

A detailed study of the process must be made by various

techniques like interviews, questionnaires etc. The data collected by these sources

must be scrutinized to arrive to a conclusion. The conclusion is an understanding of

how the system functions. This system is called the existing system. Now the existing

system is subjected to close study and problem areas are identified. The designer now

functions as a problem solver and tries to sort out the difficulties that the enterprise

faces. The solutions are given as proposals. The proposal is then weighed with the

existing system analytically and the best one is selected. The proposal is presented to

the user for an endorsement by the user. The proposal is reviewed on user request and

suitable changes are made. This is loop that ends as soon as the user is satisfied with

proposal.

Preliminary study is the process of gathering and interpreting facts, using the

information for further studies on the system. Preliminary study is problem solving

13

activity that requires intensive communication between the system users and system

developers. It does various feasibility studies. In these studies a rough figure of the

system activities can be obtained, from which the decision about the strategies to be

followed for effective system study and analysis can be take

FEASIBILITY STUDY

Feasibility study is made to see if the project on completion

will serve the purpose of the organization for the amount of work, effort and

the time that spend on it. Feasibility study lets the developer foresee the future

of the project and the usefulness. A feasibility study of a system proposal is

according to its workability, which is the impact on the organization, ability to

meet their user needs and effective use of resources. Thus when a new

application is proposed it normally goes through a feasibility study before it is

approved for development. The document provide the feasibility of the

project that is being designed and lists various areas that were considered very

carefully during the feasibility study of this project such as Technical,

Economic and Operational feasibilities. The following are its features:

TECHNICAL FEASIBILITY

The system must be evaluated from the technical point of view first. The

assessment of this feasibility must be based on an outline design of the system

requirement in the terms of input, output, programs and procedures. Having

identified an outline system, the investigation must go on to suggest the type

of equipment, required method developing the system, of running the system

once it has been designed.

Technical issues raised during the investigation are:

Does the existing technology sufficient for the suggested

one?

14

Can the system expand if developed?

The project should be developed such that the necessary functions and performance

are achieved within the constraints. The project is developed within latest technology.

Through the technology may become obsolete after some period of time, due to the

fact that never version of same software supports older versions, the system may still

be used. So there are minimal constraints involved with this project. The system has

been developed using Java the project is technically feasible for development.

ECONOMIC FEASIBILITY

The developing system must be justified by cost and benefit. Criteria to ensure that

effort is concentrated on project, which will give best, return at the earliest. One of the

factors, which affect the development of a new system, is the cost it would require.

The following are some of the important financial questions asked during preliminary

investigation:

The costs conduct a full system investigation.

The cost of the hardware and software.

The benefits in the form of reduced costs or fewer costly errors.

Since the system is developed as part of project work, there is no manual cost

to spend for the proposed system. Also all the resources are already available,

it give an indication of the system is economically possible for development.

BEHAVIORAL FEASIBILITY

This includes the following questions:

Is there sufficient support for the users?

Will the proposed system cause harm?

15

The project would be beneficial because it satisfies the objectives when developed

and installed. All behavioral aspects are considered carefully and conclude that the

project is behaviorally feasible.

SCOPE OF PROPOSED SYSTEM

Microsoft Visual Basic 6.0

Visual Basic 6.0 is Microsoft’s latest version of the Visual Basic Programming language.

Although writing programs can be a tedious chore at time. Visual Basic reduces the effort

required on your part, and makes programming enjoyable. Visual Basic makes many aspects

of programming as simple as dragging graphics objects on to screen with your mouse.

Visual Basic 6.0 is more than just a programming language; the secret to Visual Basic is in its

name” Visual”. With to days Windows Operating System, a program must be able to interact

with the screen. Keyboard , mouse and printer graphically.

The environment provided by Visual Basic is suitable for any type of application. Using this

environment, the user can visually design the objects that your application uses. Visual Basic

is not just a languages, it’s an integrated development environment in which you can develop,

run, test and debug your applications. The impressive array of programming resources

provided by Visual Basic enables to create the objects extemporaneously which can range

from pop-up menu to a message box.

A form is a major part of Visual Basic application, which allows the user to enter the data as

well as view the result. A control is an object that we draw on a form to enable or enhance

user interaction with an application. Hence a Visual Basic application is a combination of

object like forms and controls, procedures that can respond to Events and other general-

purpose procedures.

Backend

Microsoft Office Access 2007

22

Microsoft Office Access, previously known as Microsoft Access, is a relational database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately. In mid-May 2010, the current version of Microsoft Access 2010 was released by Microsoft in Office 2010; Microsoft Office Access 2007 was the prior version.

Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases.[1]

Software developers and data architects can use Microsoft Access to develop application software, and "power users" can use it to build simple applications. Like other Office applications, Access is supported by Visual Basic for Applications, an object-oriented programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating-system functions.

Access now includes support for a broader range of data types, including documents and images.

Whenever any table is updated, all reports referencing the table are also updated. Dropdown lists for a table can be modified in place. Lookup Fields, which get their values by "looking up" some value in a table, have

been updated to support multi valued lookups. Many new preset schemata are included. Access can synchronize with Windows SharePoint Services 3.0 and Office SharePoint

Server 2007. This feature enables a user to use Access reports while using a server-based, backed-up, IT managed version of the data.

System Logical Design

DATA FLOW DIAGRAM

A Data Flow Diagram (DFD) is a diagram that describes the flow of

data and the processes that change or transform data throughout a system. It’s a structured

24

analysis and design tool that can be used for flowcharting in place of, or in association with,

information oriented and process oriented system flowcharts. When analysts prepare the Data

Flow Diagram, they specify the user needs at a level of detail that virtually determines the

information flow into and out of the system and the required data resources. This network is

constructed by using a set of symbols that do not imply a physical implementation. The Data

Flow Diagram reviews the current physical system, prepares input and output specification,

specifies the implementation plan etc.

Four basic symbols are used to construct data flow diagrams. They are

symbols that represent data source, data flows, and data transformations and data storage. The

points at which data are transformed are represented by enclosed figures, usually circles,

which are called nodes.

Data Flow Diagram Symbols:-

_ Source or Destination of data

_ Data Flow

_ Process

_ Storage

25

Data dictionary

A data dictionary is a structured repository of data about data. It is a set of rigorous definitions of all DFD data elements and data structures.

A data dictionary has many advantages .The most obvious is documentation ;it is a valuable reference in any organization . Another advantage is improving analyst/user communication by establishing consistent definitions of various elements , terms , and procedures . also control information maintained for each data element is cross-referenced in the data dictionary. A data dictionary is an important step in developing a database.

Database users and application developers can benefit from an authoritative data dictionary document that catalogs the organization, contents, and conventions of one or more databases. This typically includes the names and descriptions of various tables and fields in each database, plus additional details, like the type and length of each data element. There is no universal standard as to the level of detail in such a document, but it is primarily a weak kind of data.

The three classes to be defined are data elements, data structures, and data flows and data stores.

Data element is the smallest unit of data that provides for no further decomposition.

Data structure is a group of data elements handled as a unit.

Data flows and data stores are data structures in motion and data structures at rest, respectively.

SYSTEM PHYSICAL DESIGN

SYSTEM DESIGN

Introduction to System Design

Design is the first step into the development phase for any engineered

product or system. Design is a creative process. A good design is the key to effective

system. The term “design” is defined as “the process of applying various techniques

and principles for the purpose of defining a process or a system in sufficient detail to

permit its physical realization”. It may be defined as a process of applying various

techniques and principles for the purpose of defining a device, a process or a system

in sufficient detail to permit its physical realization. Software design sits at the

technical kernel of the software engineering process and is applied regardless of the

development paradigm that is used. The system design develops the architectural

detail required to build a system or product. As in the case of any systematic

approach, this software too has undergone the best possible design phase fine tuning

all efficiency, performance and accuracy levels. The design phase is a transition from

a user oriented document to a document to the programmers or database personnel.

System design goes through two phases of development: Logical and Physical

Design.

Input design

The design of input focuses on controlling the amount of input required,

controlling the errors, avoiding delay, avoiding extra steps and keeping the

process simple. The input is designed in such a way so that it provides security

and ease of use with retaining the privacy. Input Design considered the

following things:

o What data should be given as input?

o How the data should be arranged or coded?

30

o The dialog to guide the operating personnel in providing input.

o Methods for preparing input validations and steps to follow when error occur.

OUTPUT DESIGN

A quality output is one, which meets the requirements of the end user and

presents the information clearly. In output design it is determined how the

information is to be displaced for immediate need and also the hard copy

output. It is the most important and direct source information to the user.

Efficient and intelligent output design improves the system’s relationship to

help user decision-making.

Designing computer output should proceed in an organized, well thought out

manner; the right output must be developed while ensuring that each output

element is designed so that people will find the system can use easily and

effectively. When analysis design computer output, they should :

Identify the specific output that is needed to meet the requirements.

Select methods for presenting information.

Create document, report, or other formats that contain information produced

by the system.

DATABASE DESIGN

44

A database is an organized mechanism that has the capability of storing

information through which a user can retrieve stored information in an

effective and efficient manner. The data is the purpose of any database and

must be protected.

The database design is a two level process. In the first step, user requirements

are gathered together and a database is designed which will meet these

requirements as clearly as possible. This step is called Information Level

Design and it is taken independent of any individual DBMS.

In the second step, this Information level design is transferred into a design for

the specific DBMS that will be used to implement the system in question. This

step is called Physical Level Design, concerned with the characteristics of the

specific DBMS that will be used. A database design runs parallel with the

system design. The organization of the data in the database is aimed to achieve

the following two major objectives.

Data Integrity

Data independence

Normalization is the process of decomposing the attributes in an application,

which results in a set of tables with very simple structure. The purpose of

normalization is to make tables as simple as possible. Normalization is carried

out in this system for the following reasons.

To structure the data so that there is no repetition of data , this helps in saving.

To permit simple retrieval of data in response to query and report request.

To simplify the maintenance of the data through updates, insertions, deletions.

To reduce the need to restructure or reorganize data which new application

requirements arise.

RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS):

45

A relational model represents the database as a collection of relations. Each

relation resembles a table of values or file of records. In formal relational

model terminology, a row is called a tuple, a column header is called an

attribute and the table is called a relation. A relational database consists of a

collection of tables, each of which is assigned a unique name. A row in a tale

represents a set of related values.

RELATIONS, DOMAINS & ATTRIBUTES:

A table is a relation. The rows in a table are called tuples. A tuple is an

ordered set of n elements. Columns are referred to as attributes. Relationships

have been set between every table in the database. This ensures both

Referential and Entity Relationship Integrity. A domain D is a set of atomic

values. A common method of specifying a domain is to specify a data type

from which the data values forming the domain are drawn. It is also useful to

specify a name for the domain to help in interpreting its values. Every value in

a relation is atomic, that is not decomposable.

RELATIONSHIPS:

Table relationships are established using Key. The two main keys of prime

importance are Primary Key & Foreign Key. Entity Integrity and Referential

Integrity Relationships can be established with these keys.Entity Integrity

enforces that no Primary Key can have null values.Referential Integrity

enforces that no Primary Key can have null values.

Referential Integrity for each distinct Foreign Key value, there must exist a

matching Primary Key value in the same domain. Other key are Super Key

and Candidate Keys.

Relationships have been set between every table in the database. This ensures

both Referential and Entity Relationship Integrity.

46

NORMALIZATION:

As the name implies, it denoted putting things in the normal form. The

application developer via normalization tries to achieve a sensible

organization of data into proper tables and columns and where names can be

easily correlated to the data by the user. Normalization eliminates repeating

groups at data and thereby avoids data redundancy which proves to be a great

burden on the computer resources. These includes:

Normalize the data.

Choose proper names for the tables and columns.

Choose the proper name for the data.

First Normal Form:

The First Normal Form states that the domain of an attribute must include only

atomic values and that the value of any attribute in a tuple must be a single

value from the domain of that attribute. In other words 1NF disallows

“relations within relations” or “relations as attribute values within tuples”. The

only attribute values permitted by 1NF are single atomic or indivisible values.

The first step is to put the data into First Normal Form. This can be donor by

moving data into separate tables where the data is of similar type

in each table. Each table is given a Primary Key or Foreign Key as per

requirement of the project. In this we form new relations for each nonatomic

attribute or nested relation. This eliminated repeating groups of data.

A relation is said to be in first normal form if only if it satisfies the constraints

that contain the primary key only.

Second Normal Form:

47

According to Second Normal Form, For relations where primary key contains

multiple attributes, no nonkey attribute should be functionally dependent on a

part of the primary key.

In this we decompose and setup a new relation for each partial key with its

dependent attributes. Make sure to keep a relation with the original primary

key and any attributes that are fully functionally dependent on it. This step

helps in taking out data that is only dependant on apart of the key.

A relation is said to be in second normal form if and only if it satisfies all the

first normal form conditions for the primary key and every non-primary key

attributes of the relation is fully dependent on its primary key alone.

Third Normal Form:

According to Third Normal Form, Relation should not have a non-key

attribute functionally determined by another non-key attribute or by a set of

non-key attributes. That is, there should be no transitive dependency on the

primary key.

In this we decompose and set up relation that includes the non-key attributes

that functionally determines other non-key attributes. This step is taken to get

rid of anything that does not depend entirely on the Primary Key.

A relation is said to be in third normal form if only if it is in second normal

form and more over the non key attributes of the relation should not be depend

on other non key attribute.

TESTING

SYSTEM TESTING

System testing is a critical aspect of Software Quality Assurance and represents the ultimate review of specification, design and coding. Testing is a process of executing a program with the intent of finding an error. A good test is one that has a probability of finding an as yet undiscovered error. The purpose of testing is to identify and correct bugs in the developed system. Nothing is complete without testing. Testing is the vital to the success of the system. In the code testing the logic of the developed system is tested. For this every module of the program is executed to find an error. To perform specification test, the examination of the specifications stating what the program should do and how it should perform under various conditions. Unit testing focuses first on the modules in the proposed system to locate errors. This enables to detect errors in the coding and logic that are contained within that module alone.Those resulting from the interaction between modules are initially avoided. In unit testing step each module has to be checked separately. System testing does not test the software as a whole, but rather than integration of each module in the system. The primary concern is the compatibility of individual modules. One has to find areas where modules have been designed with different specifications of data lengths, type and data element name. Testing and validation are the most important steps after the implementation of the developed system. The system testing is performed to ensure that there are no errors in the implemented system. The software must be executed several times in order to find out the errors in the different modules of the system. Validation refers to the process of using the new software for the developed system in a live environment i.e., new software inside the organization, in order to find out the errors. The validation phase reveals the failures and the bugs in the developed system. It will be come to know about the practical difficulties the system faces when operated in the true environment. By testing the code of the implemented software, the logic of the program can be examined. A specification test is conducted to check whether the specifications stating the program are performing under various conditions. Apart from these tests, there are some special tests conducted which are given below: Peak Load Tests: This determines whether the new system will handle the volume of activities when the system is at the peak of its processing demand. The test has revealed that the new software for the agency is capable of handling the demands at the peak time. Storage Testing: This determines the capacity of the new system to store transaction data on a disk or on other files. The proposed software has the required storage space available, because of the use of a number of hard disks. Performance Time Testing: This test determines the length of the time used by the system to process transaction data. In this phase the software developed Testing is exercising the software to uncover errors and ensure the system meets defined requirements. Testing may be done at 4 levels

• Unit Level

• Module Level

57

• Integration & System

• Regression

UNIT TESTING A Unit corresponds to a screen /form in the package. Unit testing focuses on verification of the corresponding class or Screen. This testing includes testing of control paths, interfaces, local data structures, logical decisions, boundary conditions, and error handling. Unit testing may use Test Drivers, which are control programs to co-ordinate test case inputs and outputs, and Test stubs, which replace low-level modules. A stub is a 40dummy subprogram.

MODULE LEVEL TESTINGModule Testing is done using the test cases prepared earlier. Module is defined during the time of design.

INTEGRATION TESTINGIntegration testing is used to verify the combining of the software modules. Integration testing addresses the issues associated with the dual problems of verification and program construction. System testing is used to verify, whether the developed system meets the requirements.

REGRESSION TESTINGEach modification in software impacts unmodified areas, which results serious injuries to that software. So the process of re-testing for rectification of errors due to modification is known as regression testing. Installation and Delivery Installation and Delivery is the process of delivering the developed and tested software to the customer.

58

IMPLEMENTATION

59

SYSTEM IMPLEMENTATION

Implementation includes all those activities that take place to convert from the old system to the new. The old system consists of manual operations, which is operated in a very different manner from the proposed new system. A proper implementation is essential to provide a reliable system to meet the requirements of the organizations. An improper installation may affect the success of the computerized system

IMPLEMENTATION METHODS: There are several methods for handling the implementation and the consequent conversion from the old to the new computerized system.

The most secure method for conversion from the old system to the new system is to run the old and new system in parallel. In this approach, a person may operate in the manual older processing system as well as start operating the new computerized system. This method offers high security, because even if there is a flaw in the computerized system, we can depend upon the manual system. However, the cost for maintaining two systems in parallel is very high. This outweighs its benefits.

Another commonly method is a direct cut over from the existing manual system to the computerized system. The change may be with in a week or with in a day. There are no parallel activities. However, there is no remedy in case of a problem. This strategy requires careful planning.

A working version of the system can also be implemented in one part of the organization and the personnel will be piloting the system and changes can be made as and when required. But this method is less preferable due to the loss of entirety of the system.

IMPLEMENTATION PLAN:The implementation plan includes a description of all the activities that must occur to implement the new system and to put it into operation. It identifies the personnel responsible for the activities and prepares a time chart for implementing the system. The implementation plan consists of the following steps.

o List all files required for implementation.

o Identify all data required to build new files during the implementation.

o List all new documents and procedures that go into the new system.

The implementation plan should anticipate possible problems and must be able to deal with them. The usual problems may be missing documents; mixed data formats between current and files, errors in data translation, missing data etc

LIMITATIONS

AND

FUTURE SCOPE

61

Limitations

The new system has been designed to meet almost all of the user requirements but it too has

certain limitations some of which can be enhanced in the future enhancements or updates.

Supports only Multiple choice and no Theory

The existing system supports only multiple choice questions and these can be used

only for the logic testing of the student whereas paper based tests can provide a overall result

of the users knowledge for that topic. This will do injustice to users who are sometimes aware

of answers but not sure completely. It supports only two values True and False. If the selected

answer is true the user gets marks, If not loses.

No Image Support

The existing system has no image support at present and so images and diagrams

cannot be included in the exam which would make it very difficult to ask certain questions in

certain subjects. Providing diagrams externally is at present the only feasible choice

available.

No Back Option AvailableThe existing system also lacks a back option which would take a user to a previously answered question in case he wants to check or change his choice. This makes it very difficult and quite stressf ul for the user to choose an option which is totally contrary to the theory tests in which the user can review and change his answers. This has been an important point in the proposed enhancements in the system.

Exam Time Cannot be Modified

The existing system allows the exam time to be set only once at the time of system

set up which cannot be changed as per desired and all the exams will be conducted for the

62

preset time only. If the user wants to increase or decrease the time for exams the system will

have to be set up again. This is also one of the proposed enhancements.

Future Scope

Enhancements are the perquisite for development of a system. Every existing system has

proposed enhancements which make it better and easier to use and more secure. The

enhancements that have been proposed for this system are listed here.

Including Image Support.

The existing system has no image support due to which the images cannot be used. It

will be one of the priorities in the proposed enhancements to enable Image Support in the

system.

Including Back Option

The new system will have a back option which will enable the users to go back to

previously answered questions and change them if needed. It will enable the user a hassle free

exam so that the user can properly utilize the total time allotted for the test.

Facility to Set Exam Time.

The new system will allow the faculty to set the exam time for a particular subject. It

will increase the efficiency of the system greatly as it will enable each subject to be tested for

a different duration as desired and required.

CONCLUSION

This project is about the designing the railway reservation system using M S Access, as back

end and Visual Basic 6.0 as front end. This project presents an investigative view of present

railway reservation system including the history of booking tickets and cancelled tickets.

Present system of railway reservation system is having some shortcoming on which we have

tried to work on that to eliminate the disadvantages.

We have made a database for passengers and trains and connected these two tables from

the custom made data entry form built in Visual Basic 6.0. There are options for new entry

which will be stored in M S Access database and retrieved from database in future.

This project was a small attempt to make the railway reservation system using M S Access,

and Visual Basic 6.0.

In the last we conclude that Indian Railway is having a strong IT Infrastructure and a well-

equipped railway reservation system but there is some shortcoming in the system on which

we have tried to work on it and successfully completed our project.
