INTRODUCTION

In the world, every sales person and manager is looking

for the showroom management software that could make their task easier. They

hope for car showroom management software that will help them to automate

processes, quickly analyse data and reports and share this data when they need to.

There are many options for showroom management tools.

For optimal showroom management process, you need

robust functionality for managing your logistic facilities. Using this software we

can reduce the cost of warehousing, reduces paperwork of company, reduces time,

transportation of companys products, order fulfilment etc...

Showroom management tools are a group of software

or computer applications that help you manage the sales process for your

business. Showroom management tools include functions that help with data

collection, invoice printing, billing, sales and purchasing order and its necessary

processing. Features of showroom management System can vary greatly, so it is

important that you find one that fits the needs of your business.

Need for this system

You can significantly improve inventory turnover,

optimize flow of goods and shorten routes within your warehouse or distribution

centre. Additional benefits of this software include improved cash flow, visibility;

decision making. This software is user friendly and hence easy to use. We can

also manage the nature of sales and purchase of the company who introduces the

available products from warehouse to customers.

As we know manual system are quite tedious, time consuming,

and less efficient and accurate when compared to a computational system.


10/58

This system solves the disadvantages like time consuming, less accuracy, less

efficiency, lots of paperwork, slow data processing, not user friendliness, difficult

to maintain records. This system provides user efficient working environment and

more output can be generated through this. This system provides user friendly

interface resulting in knowing each and every usability features of system. This

system completes the work in a very less time resulting in less time consumption

and high level of efficiency. The calculation made very easy and quickly and

records are directly saved into database and that database can be maintained for

long period of time. Also this system provides high level of security. So that only

admin and specified sales representatives of company can login to the sales

department software to access and work with this software.

Salient features of the system

For any software project the primary parameter that should be

taken into account are time, size and effort. So we need a system where we can

deliver the correct results that would ultimately lead to a position where the

overall cost and time will be consolidated.

Hence the organization which implements such a process

can produce better results. Showroom management software is the application of

knowledge, skills and technologies to project activities to meet the project

requirements.

Manual work is reduced. Retrieval and access of information is easy Transactions are processed quickly

Easy tracking of products We can efficiently and effectively handle stock management accurately

BACKGROUND STUDY

Existing System

In competitive business organization the ability to efficiently

align resources and business activities with strategic objectives can mean the

difference between succeeding and just surviving. To achieve strategic alignment,

organization are increasingly managing their activities and processes as projects-

in essence, projecting their business to monitor performance more closely and

make better business decision above their overall work portfolio.

By planning and tracking projects with clarity and precession,

organizations can respond with greater ability to the demands of fast changing

business environment. Making strategic goals or reality requires technology that

is robust enough to support your core business and yet flexible enough to

accommodate your existing processes. The CAR SHOWROOM

MANAGEMENT SOFTWARE is one of the existing tools that are helpful for

car showroom management. The primary purposes of any such tools are to

improve productivity, reduce cycle time, decreases costs by increasing quality

Drawbacks of the Existing System

Manual system uses huge amounts of papers and stores. Difficulty in tracking and retrieving data from the abundant papers is quite

difficult.

It is not easy to recognize the errors occurred. Time consuming process.


13/58

13

Proposed System

The existing tools do not consider all the factors that affect a

project directly. The entire process is built upon using just one or two parameters

which do not give us complete and desired results. So we need a system where

we can deliver the correct results that would ultimately lead to a position where

the overall cost and time will be consolidated.

We can efficiently and effectively handle stock management processaccurately

Manual work can be reduced Retrieval and access of information is easy Transactions are processed quickly Easy tracking of products

PROBLEM FORMATION


15/58

15

PROBLEM FORMULATION

Main objectives

Manual system uses huge amounts of papers and stores: we can reduce thisproblem using Car showroom management system.

Difficulty in tracking and retrieving data from the abundant papers is quitedifficult. This software makes the entire process easy.

Human activities while handling with the books will always be timeconsuming. Showroom Management tool will save the time.

Using this software we can reduce the cost of warehousing, reducespaperwork of company, reduces time, transportation of companys products,

order fulfilment etc...

This system solves the disadvantages like time consuming, less accuracy, lessefficiency, lots of paperwork, slow data processing, not user friendliness,

difficult to maintain records

Methodology

Methodology means a way of doing things in a structured

manner. The Methodology is designed to help to the part consistently, regardless

of nature of the work, to manage the process involved and solve complex

problem in a structured and co-ordinate manner.

For any software project the primary parameters that should

be taken into account are time, size, and effort. The entire process is built upon

using just one or two parameters which do not give us complete and desired

results. So we need a system where we can deliver the correct results that would

ultimately lead to a position where the overall cost and time will be consolidated.

Platform

Introduction To .Net

.NET is a set of technologies designed to allow

applications to work together whether they reside on the users hard drive, the

local network, a remote computer, or the Internet. It is the common code

framework used by nearly all Microsoft applications, such as Windows, Internet

Explores and IIS Web server, and it is also the framework for third party

application development based on Microsoft technology. Microsoft .NET relies

on standards such as XML, SOAP and UDDI to make it easy for networked

objects to discover other networked objects and communicate with

them. Because .NET applies to almost all Microsoft products, the company

divides .NET into several areas including .NET servers and the .NET

Framework.

. NET Framework

The .NET Framework includes the runtime andcompiles time services required to run a .NET application. Compile time is when

the developer is compiling the source. Runtime is when the compiled code is

executing in memory. At the centre of the runtime execution of .NET code is the

Common Language Runtime (CLR).

What Is Microsoft .NET?

Microsoft .NET is software that connects information,

people, systems, and devices. It spans clients, servers, and developer tools, and

consists of:

The .NET Framework 1.1, used for building and running all kinds ofsoftware, including Web-based applications, smart client applications,

and XML Web servicescomponents that facilitate integration by

sharing data and functionality over a network through standard,


17/58

17

platform-independent protocols such as XML (Extensible Markup

Language), SOAP, and HTTP.

Developer tools, such as Microsoft Visual Studio .NET 2003 whichprovides an integrated development environment (IDE) for maximizing

developer productivity with the .NET Framework.

A set of servers, including Microsoft Windows Server 2003,Microsoft SQL Server, and Microsoft BizTalk Server, that

integrates, runs, operates, and manages Web services and Web-based

applications.

Client software, such as Windows XP, Windows CE, and MicrosoftOffice XP, that helps developers deliver a deep and compelling user

experience across a family of devices and existing products.

The .NET Framework is composed of the common language runtime

and a unified set of class libraries.

.NET Supported Languages

Currently .NET supports the following languages:

C# C++ with Managed Extensions VB .NET ASP.NET (although this one is more a subset of VB .NET) Jscript.NET

In short .NET is:

A platform neutral framework. Layer between the operating system and the programminglanguage.

It supports many programming languages, including VB.NET,C# etc.


18/58

18

NET provides a common set of class libraries, which can beaccessed from any .NET based programming language. There will not

be separate set of classes and libraries for each language. If you know

any one .NET language, you can write code in any .NET language!!

In future versions of Windows, .NET will be freely distributed aspart of operating system and users will never have to install .NET

separately.

VB.NET

Visual Basic .NET is a major component of Microsoft

Visual Studio .NET suite. The .NET version of Visual Basic is a new improved

version with more features and additions. After these new additions, VB qualify

to become a full object-oriented language such as C++. In this article, I will try to

introduce you to VB.NET and will cover new additions to the language. I will

also compare VB 6.0 and VB.NET and how to develop simple applications in

VB.NET. VB.NET is the following version of VB 6.0. Microsoft .NET is a new

programming and operating framework introduced by Microsoft. All .NET

supported languages access a common .NET library to develop applications and

share common tools to execute applications. Programming with Visual Basic

using .NET is called VB.NET.

The Imports Statement

Most of the .Net types are defined in namespaces. A

namespace is a scope in which managed types are defined. If you see .NET

Framework Class Library, youll see hundreds of namespace. For example,

System namespace contains types such as Console, Object and so on. If you want

to access Console class, you need to import System namespace in your

application by using Imports directive. For example, if you want to use the

Console class, which is defined in the System namespace, you need to add the

following line in the application: Imports System.


19/58

19

Features of VB.Net are:

Object Oriented ProgrammingAll managed types in VB are derived from the system.

object class. As your requirements dictate, you can choose to use object-oriented

features.

Structured Error HandlingThis has a clean, concise Structured Exception Handling.

Support Server-side programmingVB.Net has simplified server side programming. Server

Explorer, which is included in the Visual Studio IDE, makes it easy to develop

server-side components and web applications.

Supports inheritanceWe can create one form and inherit from it to create

another one that adds to it functionality.

Supports overloadingWe can create one or more sub or function with the same

name but different parameters. This method is beneficial when we want to apply

the same programming logic for different data types.

Dont support control arraysVb.Net doesnt support control arrays because the

architecture of the .Net framework doesnt support control arrays.


20/58

20

Offers an Integrated Development Environment

The Development Environment of VB.Net is integrated

with that of other. Net languages, Visual c# and Visual C++. Net.This has proved

advantages for all Visual Studio.Net Programming languages. Eg:-A developer

using Visual C# will find it easy to switch to VB,Net and vice-versa.

Integrates with CLR

VB.Net integrates with the .Net framework and generates

code that is targeted at the CLR.The classes and data types used in VB.Net are

from the .Net framework.Therefore,VB.Net applications can achieve

interoperability with other Visual Studio.Net applications that also derived

from .Net framework class.

Supports console-based programming

VB.Net provides VBC.Exe compiler compile console

based applications.

Provides advanced controls

VB.Net provides advanced controls for high level

programming. Eg:-FileSystem Watcher control monitors a directory for the

presence of a file or types of files.

MS ACCESS 2003

Introduction to Databases and RDBMS

A database is a collection of files, a Database Management

System (DBMS) is a program (set of programs) that stores and organizes

data. One such organization method is relational where data is organized by

means of related tables called relations and hence the name Relational Database

Management System (RDBMS). RDBMS stores information in related relations

(tables, subjects) which can be related using common fields.

MS Access is a Relational Database Management System (RDBMS). Like all

database systems MS Access stores database information in a database file (MS

Access uses .mdb extension), MS Access .mdb files store information about your

database objects such as tables, queries, forms, macros, reports, access web

pages, and modules. An RDBMS is used to store, retrieve and update data via

facilities and mechanisms that are supported from within the database system,these mechanisms include tools to:

view the data. update the data. facility to store data (Tables). present data (Forms, Reports, Access Web Pages). generate reports from the database dynamically (Wizards). Security utilitiesonly authorized users can access the database. retrieve subset of the data based on a defined selection criteria (Queries). MS

Access uses Structured Query Language (see query section) to support query

services.

backing up and restoring data. Facilities to share the date


22/58

22

MS Access 2003 supports all these features and provide

objects that are used to implement each tool. the relational database objects that

are supported by MS Access 2003 are organized in a database file. A databasefile is a container for organized tables, queries, forms, reports, access web pages.

and modules. A table object is the fundamental structure that is used to store in-

formation about subjects related to your application (Students, Courses, Instruc-

tors, Employees, etc.). A Query object allows retrieving a subset of the records

from a table or tables. A Form object allows you to create Graphical User Inter-

face (GUI) for accessing your information including adding, updating, deleting,and viewing your data. A report object allows you to print information, calcu-

late total among other things. Pagesobject allows us to generate html files that

are ready to be published on the web. Macros object allows us to create individ-

ual macro actions in response to events (close a form, open form, run a module,

etc.). Modules object allows us to store Visual Basic Code (VBA) to carry cer-

tain tasks such as open a form, update data, trap errors. RDBMS uses storage

and retrieval methods that are based on mathematics which makes RDBMS

more reliable than other DBMS systems. RDBMS uses the following languages:

Data Definition Language (DDL) for defining and organizing tables and theirrelationships.

Data Access Language (DAL) to retrieve and update stored data. Structured Query Language (SQL) is used to support quires (answer ques-

tions about the data).


23/58

23

Table Definitions:

Primary key , are fields in the table that uniquely identifies a record. Oneor more fields whose values uniquely identify each record in a table. Null

values are not allowed in a primary key and a primary key must always have

a unique index. A primary key is used to relate a table to foreign keys in other

tables.

Foreign Key, One or more table fields that refer to the primary key field inanother table. A foreign key indicates how the tables are related.

Candidate key, if a field could uniquely identify a record then its called acandidate key.

Composite key, is a primary key that is made of 2 or more fields. Domain, all entries in table for one attribute belong to the same domain

which is a list of all possible values of an attribute. For example US states is

the domain for a states field.

Indexes , A feature that speeds up searching and sorting in a table basedon key values and can enforce uniqueness on the rows in a table. The primary

key of a table is automatically indexed. Some fields can't be indexed because

of their data type such memo fields.

Relationships

Relationships are used to extract information form multi-ple tables (i.e., to join one more tables). Primary and forign keys are used to join

tables in one of the following forms of relations:

1. one-to-one relationship, when one record in the first table relate to one and

only one record in the related table (foreign key).

2. one to many relationship, when one record in the primary table is related to

many records in the related table. this is the most common relationship. For ex-

ample there is a one to many relationship between Student table and the Courses

table since each student can register for multiple classes.


24/58

24

3. many to many relationship, when many records in one table are related to

many records in the related table. For example table Orders has a one to many

relationship with table Orders. MS Access does not support many-to-many rela-

tionship , we can implement it in access by breaking the relationship into two one

to many relationships using Junction tables. Junction tables are tables that are

used to to link two tables in a many-to-many relationship by including the pri-

mary keys from both tables.

Relationships Definitions

Referentional Integrity, when all values in related tables have a primary val-ues in the primary table.

Cascading updates, a feature that is supported by MS access that is used topreserve the Integrity of the data (Referentional Integrity). For example up-

dating a record in the Products table results in cascading the updates all re-

cords in the Orders table.

Cascading Deletes, a feature that is supported by MS access that is used topreserve the Integrity of the data (Referentional Integrity). For example de-

leting a record in the Products table results in cascading the delete of all re-

cords in the Orders table.

Access vs. Excel

Why store categories of information in separate tables?

Why not create one all-inclusive spreadsheet, using Microsoft Excel? Excel is

ideally suited to storing numerical data because of its ability to perform complex

calculations and to graph data. Access, on the other hand, is designed to manage

records by means of storing related data in separate tables whose information can

then be combined and retrieved based on criteria that you define. A business

wanting to keep track of suppliers, buyers and orders would be best served by

using a database, since those three categories contain relational data.


25/58

25

About saving in Access

Access automatically saves data as you move from one

record to another. (NOTE: This means once you type over old information, that

old information is lost and youd need to re-enter it to get it back.)

Access does prompt the user to save newly created objects before closing them

out, and to save objects to which you made structural changes. The user can

choose to save those changes or not.

Microsoft Access 2003 Table Views

Microsoft Access provides multiple views to work with

tables that are custom to your particular task. For example if you are trying to

edit records and modify information in the table then you can work with

the Datasheet view to directly enter, update and delete data value from the ta-ble. To work with the design of a table such as changing field type and size or

adding a primary key to your table you work with the Design View.

SYSTEM ANALYSIS AND DESIGN

Fact Finding

After obtaining this background knowledge the analyst begin

to collect data on the existing systems output, inputs and costs. The following

are some of the methods for fact finding.

Review of Written Documents

When available all documentation on data carries (forms,

record, manuals etc...)Is organized and evaluated. Including in procedure manuals

are the requirements of the system, which helps in determining to what extend

that are met by the present system. Unfortunately, most manuals are not up to

date or may not be readable. Day to day problem may have forced changes that

are not reflected in the manual. Furthermore, people have a tendency to ignore

procedures and find shortcuts as long as the outcome is satisfactory.

SYSTEM DESCRIPTION

System analysis is the reduction of the entire system by

studying the various operations performed and the relationships with the system

and the requirement of its successor. A system can be defined as an orderly

grouping of independent component linked together according to a plan to

achieve a specific objective.

System study is a very critical activity while developing a

software application. This stage involves study of existing system and interacting

with users, which determines user requirements, and their expectations of the

proposed system. Series of discussions were made with users to arrive at a

solution to the problems they usually face. Determinations of system

requirements were preceded by a detailed study of the existing system in order to

analyze its functioning in depth. Study of all existing documentation and

procedures pertaining to the human resource management in the existing system

was made.

DATA FLOW DIAGRAM

The objective of the method is to provide a systematic

approach for the derivation of program structure the global view of softwareand the underpinning of architectural design. Beginning with a fundamental

system model, information may be represented as a continuous flow that

undergoes a series of transforms as it evolves from input to output. The data flow

diagram is used as a graphical tool to depict information flow. Data flow oriented

design defines a number of different mappings that transforms information flow

into program structure.

Each software design methodology has strengths and

weaknesses. An important selection factor for a design method is the breadth of

applications to which it can be applied. A data flow oriented approach to design

is best suitable when information is processed sequentially and no formal

hierarchical data structure exists; for example microprocessor control

applications, complex numerical analysis procedures, process control, and many

other engineering and scientific software fall into this category.

SYMBOLS USED IN DATA FLOW DIAGRAM:

Square defines a source or destination of system data. Arrow identifies data flow through which information flows. Circle represents a process that transforms incoming data flows into outgoing

data flows.

Open rectangle is a data store.


30/58

30

BASIC DFD SYMBOLS

A data flow is a route, which enables packets of

data to travel from one point to another. Data

may flow from a source to a processor and from

data store or process. An arrow line depicts the

flow, with arrowhead pointing in the direction

of flow.

A process represents transformation where

incoming data flows are changed into outgoing

data flows.

A data store is a repository of data that is to be

stored for use by a one or more process may besimple as buffer or queue or sophisticated as

relational database. They should have clear

names. If a process merely uses the content of

store and does not alter it, the arrow head goes

only from the store to the process. If a process

alters the details in the store then a doubleheaded arrow is used.

A source or sink is a person or part of an

organization that enters or receives information

from the system, but is considered to be outsidethe context of data flow model.


31/58

31

STEPS TO CONSTRUCT DATA FLOW DIAGRAM

Process should be named and numbered for easy reference. Each nameshould be representative of the process.

The direction of flow is from top to bottom and from left to right. When a process is exploded in to lower level details they are numbered. The names of data stores, sources and destinations are written in capital

letters.

FEASIBILITY ANALYSIS

Having established a system, one has to determine whether

an alternative system is feasible compared to existing system. Feasibility study is

conducted in two steps: first a project team is formed. The team develop system

flowchart that identify the characteristics of the existing system, evaluate the

performance of the system, cost, and data and select the best system for the job.

Consider the above two steps and conduct a feasibility study

in the existing system to analyse whether a new system would be more feasible

than the existing one. To perform a feasibility study, we need to consider the

economical, technical, behavioural factor in a system.

Economic Feasibility

It is most frequently used method for evaluating the

effectiveness of a system, which is commonly known as cost/benefit analysis.

The existing system is operated manually which increases the workload, so an

alternative system is developed that minimizes the workload by making use of

automated processing. The cost required for automation is compared against the

benefits drawn out of it, and since the benefits exceeds cost we go for automation

of the system.

Technical Feasibility

This is designed to fit the available software and hardware

chosen. The data storage requirements are available. Already existing resources

can meet the expenses of the existing system in future. Out of it, we cant able to

get any solutions that are related with the proposed system.


34/58

34

Behavioural Feasibility

It involves performing an estimate, how strong a reaction the

user staff is likely to have towards the development of a computerized system.

The introduction of new system requires special efforts to educate and train the

user to perform the operation automatically.

The needs of various people affected by the

proposed system must be taken into account. The social cost must also be

evaluated for the proposed system. So the benefits are more and cost wise low.

Hence it is accepted.

Input Design

Once the analysis of the system has been done, it would be

necessary to identify the data that is required to be processed to produce the

outputs. Input design features can ensure reliability of the system and generate

reports from the accurate data.

The various objectives of the input design are:

Control the amount of input

Avoiding unwanted delay Avoiding errors in the data Keeping the process simple

The validations are carried out easily and there will be no

difficulty in adding a new entry.


35/58

35

Output Design

Computer output is the most important and direct source of

information to the user. Efficient, intelligible output design should improve the

systems relationships with the user and help in the decision making. A major

form of output is hardcopy from the printer. Printouts have been designed around

the outputs requirements of the employees.

There are several output reports they are:

Database Design

This activity deals with the design of the physical

database .A key is to database how the access paths are to be implemented. In

database design, several specific objectives are to be considered. They are:

Controlled Redundancy Recover from Failure Privacy and security Performance Data Independence Ease of use Accuracy and integrity Avoiding inordinate delays

The overall objective in the development of database

technology has been to treat. Data as organizational resource and as an integrated

whole database management system allow the data to be protected and organized

separately from other resource.

Database can be defined as an integrated collection of data.

Database is acrucial factor in the performance of system both in term of system

timings and in the case with which the system can be maintained or modified.

Data store could have been implicit or explicit in the logical

store and physical file from them.

If the data management software can provide centralized

access to the data from the program, it is possible to treat the data as a separate

resource. The organization of the data in a database aims three major objectives

namely data integration, data integrity and data independence.


45/58

45

Database Normalization

Normalization has been carried out for the following reasons:

To structure the data To permit simple retrieval of data in the response to queries. To simplify the maintenance of the data through updates, insertion and

deletions.

To reduce the needs to restructure, if reorganizes data when newapplication requirements arise.

To avoid redundancy and data dependencies.

FUNDAMENTAL DESIGN CONCEPTS FOR

THE SYSTEM DEVELOPMENT

The design concept used here is the waterfall or phased life

cycle model. This model segments the software life cycle into series of

successive activities. Each phase requires well defined requirements; utilize well

defined process and results in well-defined output. Resources are required to

complete the processes in each phase and each phase is accomplished through the

application of explicit methods, tools and techniques.

The phased is also called waterfall model because of

sequential movement from one phase to another. Following are the phases of

development cycle:

Conception Initiation Analysis Design Construction Testing Implementation and maintenance

CONCEPTION

System development life cycle starts with the conception

phase. This phase is triggered by a competitor, a problem or an opportunity.

Certain important issues are clarified at this stage like:

The problem is perceived The goals to be achieved The benefits from the solution The scope of the project

INITIATION

In this phase, the software engineers work with users to carry

out a macro level study of the users requirements. The software engineers define

the various alternatives possible and the cost benefit justification of these

alternatives.

ANALYSIS

In this phase, the software engineers carry out a detailed

study of the users requirements. They then arrive the proposed system to be built.

The model of this system is used to freeze all requirements before the next phase

begins. The phase generates functional specifications, which contains:

Outputs to be produced Inputs that need to be received. Procedures that will get the output from the input. Acceptance test to list the types that the user can carry out to ensure that

the system is acceptable.

DESIGN

In this phase, the functional specifications are used for

translating the model into a design of the desired system. From the DFD the next

step is the definition of the modules and their relationships to one another in a

form called structured charts, using a data dictionary and other structured tools.

The purpose of the design phase is to specify a particular software system that

will meet stated requirements.

CONSTRUCTION

In this phase actual code that will be delivered to the

customer as the running system. Individual modules developed in this phase are

tested before delivering to the next phase.

TESTING

All the modules that have been developed before are

integrated or put together in this phase and tested as the complete system. A

system is tested for online response, volume of transaction, stress, recovery from

failure and usability.

IMPLEMENTATION

Implementation means converting a new system design in to

operation. This involves creating computer compactable files.

SYSTEM TESTING

Testing is a set of activities that can be planned in advance

and conducted systematically. System testing is a stage of implementation, which

is aimed at ensuring that the system works accurately and efficiently before live

operations commences. Testing is vital success of the system. System testing

makes a logical assumption that if all the parts of the system are correct, goal will

be successfully achieved. The different types of testing are unit, integration,

validation, output, performance and acceptance testing. IN this project following

two tests are performed:

Black box testing

White box testing

BLACK BOX TESTING

This testing is done to derive set of input conditions that will

fully exercise all functional requirements for a program. Black box testing is used

to find error in following categories:


52/58

52

Incorrect or missing functions. Interface errors. Errors in data structures. Initialization Errors.

WHITE BOX TESTING

It is used to derive tests cases.

To guarantee that all independent paths within a module have beenexercised at least once.

To check all the logical decisions on their true and false side To execute all loops within their operational bounds.

IMPLEMENTATION

Implementation is the final important phase in the life cycleof a new system. The term implementation provides a wide range of meaning i.e.,

from conversion of a basic application to a complete replacement by a new

computer system. In short, implementation is the process of converting a new

system into an operating one. Under this smaller work the following are the

major steps in the implementation of the system

Installation of hardware, if required. The newly developed software is newly loaded. Different end users are trained to operate the new system. Distribution of user manual.

The implementation phase of this project was carried out according to the

strategies described above.

CONCLUSION & SCOPE OF THE SYSTEM

The system as the name indicates, CAR SHOWROOM

MANAGEMENT SYSTEM is used to purchase and sales the cars in easiest way.

The various processes of the construction of the new system have been done. The

customized progresses are effective and easy to handle. The customized modules

satisfy the user needs.

The user-friendly software, CAR SHOWROOM

MANAGEMENT SYSTEM successfully overcomes strict and severe validation

checks performed using the test data. The results attained were fully satisfactory

from the user point of view. An attempt was made to obtain maximum perfection

in documenting the software in a simple, precise and self-explanatory manner.

The system was verified with valid as well as invalid data

in each manner. The system is done with an insight into the necessary

modifications that may require in future. Hence the system can be maintained

successfully without much rework.

FUTURE ENHANCEMENTS

This application avoids the manual work and the

problems concern with it. It is an easy way to obtain the information regarding

the various products information that are present in the Super markets.

Well I and my team members have worked hard in

order to present an improved website better than the existing ones regarding the

information about the various activities. Still, we found out that the project can be

done in a better way. Primarily, when we request information about a particular

product it just shows the company, product id, product name and no. of quantities

available. So, after getting the information we can get access to the product

company website just by a click on the product name .

The next enhancement that we can add the searching

option. We can directly search to the particular product company from this

site .These are the two enhancements that we could think of at present.
