1. INTRODUCTION

1.1 OVERVIEW OF THE PROJECT

The proposed project is developed to manage the automobile in the automobile dealer

company. The main module in this project is login, automobile management, customer

management, sales, complaints and reports. The first module is the login. The automobile

showroom owner should login to the project for usage. The username and password are

verified and if it is correct, next form opens. If the username and password are not correct, it

shows the error message.

When a customer search for a automobile, if the automobile is available, they will be

taken to a page that shows the details of the automobile including automobile name,

automobile ID, uantity, price etc. !"utomobile #anagement $ystem% is useful for

maintaining automobiles, customers effectively and hence helps for establishing good relation

between customer and automobile organi&ation. It contains various customi&ed modules for

effectively maintaining automobiles and stock information accurately and safely.

When the automobile is sold to the customer, stock will be reduced automatically.

When a new purchase is made, stock will be increased automatically. While selecting

automobiles for sale, the proposed software will automatically check for total number of

available stock of that particular item, if the total stock of that particular item is less than ',

software will notify the user to purchase the particular item.

"lso when the user tries to sale items which are not in stock, the system will prompt

the user that the stock is not enough. (ustomers of this system can search for a automobile)can purchase a automobile easily by selecting fast. *n the other hand the stock of

automobiles can be maintained perfectly by the automobile shop manager overcoming the

drawbacks of existing system.

@isual basic is an ideal programming language for developing sophisticated

professional applications for #icrosoft Windows. @isual basic programming introduces a

variety of features that make it easier to create powerful, flexible applications. It makes use of

6raphical 1ser Interface for creating robust and powerful applications. The 6raphical user

Interface uses illustration for text, which enables users to interact with an application.

@isual basic has evolved from the original 5"$I( language and now contains several

hundred statements, functions, and keywords, many of which relate directly to the Windows

*perating $ystem includes,

• #ultitasking

• #essage driven architecture

• Dynamic linking

• (01 time slicing

Fe"u!es o/ &isu"l %"si0

• ?asier comprehension

•1serAfriendliness

• >aster application development

• Introduction to "ctiveAB technology

• Internet features

• $upport *+?, which is a means of communication and gives application the

power to directly use and manipulate other windows application.

• Data ?nvironment Designer, which provides an interactive design time

environment for creating programs with runtime access to data.

Ineg!"ed De&elo(#en En&i!on#en

Integrated Development ?nvironment CID? is a term commonly used in the

programming world to describe the interface and environment that is used to create

applications.

ID? is commonly referred to as the design environment or the program. ID? is made

up of components such as menu bar, tool bar, object browser, form layout window, and form

designer.

5


6/77

In visual basic 8.: ID? is a #ultiple Document Interface C#DI format. In #ultiple

Document Interface format, the windows associated with the project will stay within a single

container known as the parent. (ode and form based windows will stay within the main

container form.

@isual basic can be used to create the following types of applications.

• $tandard ?B?

• "ctive ?B?

• "ctiveB D++

• "ctiveB (ontrol

• @5 application wi&ard

E&en d!i&en (!og!"##ing

@isual basic allows adopting more of a parallel approach, with independent sections

of code for each option that the user may select. This is known as ?vent Driven

0rogramming. ?vent Driven 0rogramming is based on the #essage Driven "rchitecture of

windows. @isual 5asic programs are built around events. ?vents are various things that can

happen in program. In ?vent Driven application, the program statements are executed only

when a particular event calls specific parts of the code that is assigned to the event.

>or example consider textbox control and some of its events,

• (lick event fires when text box control is clicked.

• #ouse move event is fired when mouse is moved over the text box.

D"" "00ess o(ions

#icrosoft visual data tools allow the ability to view and manipulate tables, views,

stored procedures, and database schemas on $E+ server and *racle systems. @isual 5asic

provides a variety of options to access emote (lientF$erver databases.

$DO O%e0 Model

@isual 5asic supports "ctiveB Data *bjects #icrosofts new, high level interface to

all kinds of data. "D* objects can be created at designA time using the updated Data?nvironment Designer. "D* is an interface for both local and remote data access, remote and

6


7/77

disconnected record sets and hierarchical record sets. The "D* object model provides an

easyAtoAuse set of objects, properties, and methods for creating script that access data in

databases.

"D* consists of seven objects, three of which are independent and four are dependent

objects. Independent objects can exist by themselves) dependent objects must exist in

connection with an independent object.

• #ajor features are easier comprehension, faster application development and other

aspects such as "ctiveB, Internet features and @5 script.

MS3$CCESS

#icrosoft "ccess is a powerful database management system and the user can create

entire application that reuires little or no programming. It supports 61I features and an

entire programming language, @5" C@isual 5asic 8.: for application. "ccess is easy enough

to use that in a short time beginners can manage their own data. In #$ G"ccess, the database

means a collection of tables that hold data. It collectively stores all other object such as

7


8/77

ueries, forms and reports that are used to implement the database management function

effectively.

The #$A"ccess database can act as a backAend database for @isual 5asic 8.: as

affront end tool. #" "ccess supports the user with its powerful management functions.

5eginners can create their own database very simply with some mouse clicks. #$A"ccess

database supports so many data types when a user can incorporate data from other

applications. " database created in #$A"ccess can be accessed through @isual 5asic 8.:

using data control.

/ere database means a collection of related tables and a table means a collection of

number of records where a record means a collection of interArelated fields. It should be notedthat a field in an entity is used to describe straight. " single table can have any number of

indexed fields that can be used to locate records using an expression. This helps in filtering

out information according to specific criteria. " user can move inside a table very easily using

the navigator tools supported by the #$A"ccess database. " table can be accessed in a

number of ways like as a snapshot, dynast, etc.

2. S*STEM STUD*

2.1 E4ISTIN5 S*STEM

"ll automobile details like available in the company are entered and managed in this

and managed. 0rice details and stock details of the automobiles are managed separately. The

customer details are entered to call the customer for further purchase of automobile. The

8


9/77

customer name, address and phone number details are managed separately. The details are

entered and edited by the administrator.

5ut everything is done manually. #ost of the existing system is manual, so data

manipulations are not accurate and also processing time is slow. When the stock and

automobile count increases, manual manipulation of data becomes very difficult.

2.1.1 DR$W,$C6S

?ven though computeri&ed system exists, there are various drawbacks. They are as

follows.

• 1ser cannot search automobiles fast when the number of automobiles increases.

• 0rimary key fields should be used wherever necessary while designing in order to

manage database efficiently and for accessing information soon.

• $tock management is not efficiently done. 1ser can only know when the stock is

empty. 0rior information about stock is not possible.

• Takes much time for searching particular automobile details.

• Difficult to maintain automobile details and employee details

• ?xisting system is not accurate.

• ?ven though some existing systems are computeri&ed, there occur redundancy

problems due to duplication of entries.

• If the automobile entries have duplicate values, it cannot be maintained properly

and accurately

2.2 PROPOSED S*STEM

The proposed system is very useful for the employee and customers. It avoids the

overheads for the employee. They can minimi&e the working stress and can keep essential

documents related to the automobile and the passengers as a softcopy. The advantage of the

proposed system is the reduction in the cost of the office euipments and the transaction is

done uickly. "ny employee can answer if any delivery for a particular customer in a

particular day is available or not.

9


10/77

The proposed project will allow the customers to perform certain activities like login

and searching for automobiles. (ustomers may open an account with the store if they wish

including a username and password. In login form users will be authenticated and it is also

possible to find whether they are customer or admin through their login information which

was entered. " customer must be logged in before searching for automobiles for purchase.

If a user attempts to login with incorrect details, they will be not be redirected to

access the application. When a customer search for a automobile, if the stock of the

automobile is available, they will be taken to a page that shows the details of the automobile

including automobile title, automobile ID, uantity, price etc in order for sale.

2.2.1 $DV$NT$5ES OF PROPOSED S*STEM

>eatures of the proposed project are as follows.

• $tock management as well as automobile management is done very uickly as

well as efficiently in proposed project.

• "nother feature added in the project is, when the regular customers purchase

items from automobile, software will automatically give them discount offers.

• 0repares and produces accurate outputs

• educes the time needed and expenses

• #akes the information flow efficient

• ?asy report generation is possible

• 0rovides attractive user interface.

• ?fficient searching of automobile details by just entering automobile code is

possible.

). S*STEM DESI5N $ND DEVELOPMENT

).1 FILE DESI5N

Fl" File D""%"se

" flat file database is a database designed around a single table. The flat file design

puts all database information in one table, or list, with fields to represent all parameters. " flat

file may contain many fields, often, with duplicate data that are prone to data corruption. If

10


11/77

data between two flat files have to be merged, it is needed to copy and 0$#te relevant

information from one file to the other. There is no automation between flat files.

If two or more flat files that contain client addresses, it is reuired to manually modify

the address parameters in each file that contains that clients information. (hanging

information in one file has no bearing on other files. >lat files offer the functionality to store

information, manipulate fields, print or display formatted information and exchange

information with others, through email and over the Internet. $ome flat files may be attached

to external files, such as text editors, to extend functionality and manage related information.

Rel"ion"l File D""%"se

" relational database, on the other hand, incorporates multiple tables with methods for

the tables to work together. The relationships between table data can be collated, merged and

displayed in database forms. #ost relational databases offer functionality to share data2

• "cross networks

• *ver the Internet

• With laptops and other electronic devices, such as palm pilots

• With other software systems

Designing flat file databases is simple and reuires little design knowledge. >lat files

can be developed using just about any database engine. >lat files can be created in relational

database engines by not taking advantage of relational design concepts. Designing a

relational database takes more planning than flat file databases. With flat files, it is possible to

add information, as you deem necessary.

With relational databases, it is reuired to be careful to store data in tables such that

the relationships make sense. 5uilding a relational database is dependent upon the ability to

establish a relational model. The model must fully describe how the data is organi&ed, in

terms of data structure, integrity, uerying, manipulation and storage. elational databases

allow defining certain record fields, as keys or indexes, to perform search ueries, join table

records and establish integrity constraints.

$earch ueries are faster and more accurate when based on indexed values. Table

records can be easily joined by the indexed values. Integrity constraints can be established to

11


12/77

ensure that table relationships are valid. If the project is able to establish a oneAtoAmany

relationship in the data tables, relational database should be used because a flat file is not

sufficient to handle the data processing needs. elational databases offer more robust

reporting with report generators that filter and display selected fields.

elational databases offer the capability to building own reporting modules. #ost

relational databases also offer the capability to import and export data from other software.

There are three primary relational database systems, proprietary, open source and embedded.

0roprietary relational databases reuire the use of proprietary development languages, often

times, to complement $E+. #icrosoft "ccess, for example, combines @isual 5asic with $E+.

*pen source databases, such as #y$E+, are distributed freely to encourage user

development.

?mbedded, relational databases are packaged as part of other software packages, such

as with taxApreparation software packages. The vendor supplies the database, and all

manipulation tools, to control the database structure. These databases are, often times,

accompanied with tools to provide audit trails of transactions. 0roposed project uses

relational database files implementing $E+ ueries in #$ "ccess. $o 7 to many relationships

can be established between tables and the table data can be accessed soon even in the nonA

indexed locations.

).2 INPUT DESI5N

Input is any data or instructions entered into the memory of a computer. Two types of

input are data and instructions. Data is a collection of unorgani&ed items that can include

words, numbers, pictures, sounds, and video. " computer processes data into information,

which is organi&ed, meaningful, and useful. Instructions can be in the form of programs,

commands, or user responses.

12


13/77

" program is a series of instructions that tells a computer how to perform the tasks

necessary to process data into information. " command is an instruction given to a computer

program. " user response is an instruction you issue to the computer by responding to a

uestion posed by a computer program. "ny hardware component that allows entering data,

programs, commands, and user responses into a computer is an input device. Inputs of

"utomobile #anagement $ystem are eid, ename, ualification, automobileid, brand, cusid,

cusname and salary.

).) OUTPUT DESI5N

*utput design involves specifying how production of onAscreen reports and paper

based reports will occur. *utput may occur to database or file for storing information entered

or also for use by other systems. *utput is data that has been processed into a useful form

called information. >our types of output are text, graphics, audio, and video. Text consists of

characters Cletters, numbers, punctuation marks, or any other symbol reuiring one byte of

computer storage space that are used to create words, sentences, and paragraphs.

6raphics are digital representations of nonAtext information such as drawings, charts,

photographs, and animation Ca series of still images in rapid seuence that gives the illusion

of motion. "udio is music, speech, or any other sound. @ideo consists of images played back

at speeds to provide the appearance of full motion. "n output device is any computer

component capable of conveying information to a user.

).+ D$T$,$SE DESI5N

Database is designed to manage large bodies of information. The management of data

involves both the definitions of structures for the storage of information. In addition the data

base system must provide for the safety of the information solved, despite system crashes or

due to attempts at unauthori&ed access. >or developing an efficient database proposed project

have to fulfill certain conditions such as controlled redundancy.

" Data >low Diagram CD>D is a diagram that describes the flow of data and the

processes that change data throughout a system. Its a structured analysis and design tool that

can be used for flowcharting in place of or in association with information. *riented and

process oriented system flowcharts. >our 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.

+. S*STEM TESTIN5 $ND IMPLEMENT$TION

+.1 S*STEM TESTIN5

The common view of testing held by users is that it is performed to prove that there

are no errors in a program. It is extremely difficult since designer cannot prove to be one

hundred percent accurate. Therefore, the most useful and practical approach is with the

understanding that testing is the process of executing a program with explicit intention of

finding errors that make the program fail.

Testing has its own cycle. The testing process begins with the product reuirements

phase and from there parallels the entire development process. In other words, for each phase

of the development process there is an important testing activity. $uccessful testing reuires a

methodical approach. It reuires focusing on basic critical factors2

• 0lanning

• 0roject and process control

• isk management

• Inspections

• #easurement tools

• *rgani&ation and professionalism

24


25/77

Tes Pl"n

5efore going for testing, first we have to decide upon the type of testing to be carried

out. The following factors are taken into consideration2

• To ensure that information properly flows into and out of program

• To find out whether the local data structures maintains its integrity during all steps

in an algorithm execution

• To ensure that the module operate properly at boundaries established to limit or

restrict processing

• To find out whether error A handling paths are working correctly or not

• To find out whether the values are correctly updated or not

• (heck for validations

,l"09 ,o< Tesing

It is a software testing approach in which the tester doesnt know the internal working

of the item being tested. >or example in a 5lack box test, on software design the tester only

knows the input and the expected outputs. Tester doesnt know how the program derives the

output. Tester doesnt even imagine as to how, the coding is done. Tester need to know only

the specifications.

The advantages of black box testing approach are

• The test is unbiased because the designer and the tester is independent of each

other

• The tester needs no specific knowledge on any programming language

• The test is done from the point of view of the user, not the designer.

• The test can be designed as soon as the specifications are complete

The disadvantages of black box testing approach are

• The test can be redundant if the software designer has already run a test case.

• The test can be difficult to design

• Testing every possible input stream is unrealistic.

Uni Tesing

25


26/77

1nit or module testing is the process of testing the individual components

Csubprograms or procedures of a program. The purpose is to discover discrepancies between

the modules interface specification and its actual behavior. In our system each module must

be tested independently for validation.

Ineg!"ion Tesing

Integration testing is the process of combining and testing multiple components

together. The primary objective of integration testing is to discover errors in the interfaces

between the components. In our system each of the modules mentioned above, are tested for

checking the integration between them, after each of them are tested individually.

S'se# M"inen"n0e

"ll system is dynamic and subjects to constantly changing reuirements. ?ffort must

be devoted to adapting them and design must be flexible specified so that such changes can

be easily implemented. It activity is called system maintains. It includes improvement of

system functions and correction of errors. 5ack up of the entire database files are taken and

stored in secondary storage devices like magnetic tapes and disks so that it is possible to

restore the system at the earliest. If there is a break down or collapse, then the system giver

provision to restore database files, storing data in a separate secondary device leads to an

effective and efficient maintains of the system.

The master file has flags for maintains after for maintains. "fter the mentioned period,

the rejection suppliers, unused data in the files will be deleted in the master file. It method is

the increasing the memory to store the data. $oftware maintenance is a set of software

engineering activities that occur after software has been delivered for the customer and put

into operation. The success of the software and the project relies on the maintenance

procedure adopted. "s with the venture of human, not a single one is perfect. The further

modifications are left to the followers. It is because the opinion or vision or a thing differs

from individual to individual. The maintenance is performed at regular intervals to keep the

project safe and reliable.

Development is single activity maintenance is a continuous activity. #aintenance

involves activities like inspections, corrections and enhancements. *nce the system is

26


27/77

delivered and deployed, it enters the maintenance phase. The system need to be maintained

not because of some of its components wear out and need to be replaced, but because there

are some residual errors remaining in the system that must be removed as they are

discovered. It includes activities related to debugging the software after it goes live, changes

are reuired to address evolving software and enhancement to meet changing customer

reuirements. $o maintenance phase involves

• 1nderstanding the effects of change.

• Testing the new parts

• etesting the old parts that were not changed

• #aking changes to both the code and the documents.

These changes have to be designed by the user before the change can be carried out.

$ince reuirement change reuest involves cost, user will be cautious while reuesting the

software changes. The software will reuire continued support. The system maintenance

means the maintenance activities after and during the system development processes. It

include activities related to debugging the software after it goes live, changes acuired to

meet changes in user reuirement.

#aintenance phase identifies if there are any changes reuired in the current system.If the changes are identified, then an analysis is made to identify if the changes are really

reuired. (ost benefit analysis is away to find out if the change is really essential.

The term system is derived from the 6reek word systema, which means of

organi&ed relationship among functioning units of components. "nd the study of system

concepts has three basic implications2

• " system must be designed to achieve a predetermined objective

• Interrelationships and interdependence must exist among the components

• The objectives of the organi&ations as a whole have a high priority than the

objective of its subsystems.

"nalysis is the detailed study of the various operations performed by a system and

their relationships within and outside the system. >or the efficient and effective utili&ation of

the available resources, timing availability of accurate information is very important.

Information is the back bone of any organi&ation. There for, it has to be made available all

time to ensure proper decisionAmaking.

Information also has to be accurate, current, timely, relevant and usable. In other

words, an effective information system should be able to provide information to those in need

of it, at the time they need of it, at the time they need it and in the way they need it. The need

for managing data and retrieving information efficiently, lead to an extensive use of

computers in the business world.

The computers have convinced the management that computeri&ed system is

preferable to the existing system) most organi&ation has computeri&ed their application areas

using traditional file processing concepts. The computeri&ed system, by itself does not

guarantee of efficient information retrieval. The effectiveness of the system, to great deal,

depends on the way in which data is organi&ed and managed. Way in which data is organi&ed

in the existing system is not integrated, since there is no connection or integration between

one module and another on accomplishing the task.

"nalysis is detailed study of various operations performed by a system and their

relationships within and outside the system. " key uestion is !what must be done to solve

the problemJ% *ne aspect of analysis is determining the boundaries of the system and

determining whether or not a new proposed system should consider other related items. It is

the process of gathering and interpreting facts) diagnosing the problems and using the

information recommend improvements to the system.

The lists of potential threats are as follows

• ?rrors and *missions

• Disgruntled and Dishonest ?mployees

• >ire

• -atural Disaster

• ?xternal "ttack

S'se# Se0u!i'

$ecurity is a critical stage in system development. ?ven candidate system must

provide builtAin features for security and integrity of data. Without safe guards against

unauthori&ed access, fraud, embe&&lement, fire and natural disaster, a system could be so

vulnerable as to threaten the survival of the organi&ations.

To do an adeuate job on security, the risk, exposure, cost and specific measures such

as password should be analy&ed to provide protection. In addition, back up of copies of

software and recovery restart procedures must be available when needed.

The amount of protection depends on the sensitivity of data, the reliability of the user

and the complexity of the system. The motive behind security is to keep the organi&ation

running, protect data as an asset and seek management support for more installations.

S'se# Se0u!i' Me"su!es

"fter system security risk has been evaluated, the next step is to select security

measures. The measures are

• Identification

• "ccess (ontrol

• "udit (ontrol

• $ystem Integrity

Ideni/i0"ion

It is the scheme of identifying person to the system based on !$omething you know%

such as a password or a picture badge, !$omething you are% such as finger print or voice print

or !$omething you have% such as credit card, key or special terminal.

(ontrolling the access to the computer facility is secured through encoded cards or

similar devices. ?ncryption prevents intruders from accessing data by scrambling messages

across telephones to the destination.

system from external security breaches and internal fraud or embe&&lement. @arious software

security and operating procedure. 0roper back of hardware and software are extremely

important.

+.2 S*STEM IMPLEMENT$TION

$ystem implementation is the important stage of project when the theoretical design is

tunes into practical system. The main stages in the implementation are as follows2

• 0lanning

• Training

• $ystem testing and

• (hangeover planning

0lanning is the first task in the system implementation. 0lanning is deciding on the

method and the time scale to be adapted. "t the time of implementation of any system people

from different departments and system analysis involve. They are confirmed to practical

problem of controlling various activities of people outside their own data processing

departments. The line manager controlled through an implementation coAordinate committee.

The committee consists of ideas, 0roblems and complaints of user department. It must also

consider,

• The implementation of system environment.

• $elf selection and allocation for implementation tasks.

• (onsultation with unions and resources available.

• $tandby facilities and channels of communication.

=. CONCLUSION

The system is completely menu driven and extremely user friendly since it is

developed in an efficient front end tool @5. "ppropriate error messages are also provided too

guide the user in a proper and user friendly manner.

The software >$uo#o%ile M"n"ge#en S'se#? has been developed in windows

4::= environment using 0/0 as front end and #$ "ccess as back end. Time consumptions

reduced to a great extent and user as less complexity in handling it database.

The project is fully fledged and user friendly, ?nd users will be lightened in using it

software because it is easy to have bills and reports and mostly all contents to be entered are

to selected from combo box. It reduces the calculating efforts to be carried out by the staff.

31


32/77

-. SCOPE FOR FURTHER ENH$NCEMENT

>urther expansion of the system also can be done in future if needed. The application

can be enhanced in the future with the needs of the organi&ation. The database and the

information can be updated to the latest forthcoming versions.

There are also possibilities for enhancing and further developing the project with

customi&ed reports according to the latest information and needs of the company. Thus the

system can be altered in accordance with the future reuirements and advancements. $ystem

performance evaluation must be monitored not only to determine whether or not they perform

as plan but also to determine if they should have to meet changes in the information needed

for the company.

The performance of the system will be evaluated to determine whether system

achieves the results that are expected and whether the predicted benefits of the system are

reali&ed.
