ONLINE SHOPPING

INTRODUCTION:

Online shopping is a website for an online shopping store which provide different

items to the people according to their needs. This web site will provide the user to

shop online whether they are anywhere in the world. The web site will have many

products, which help the user to choose the product of their own choice with

controlled prices excluding the shipment charges. There are the member and non-

member who buy the product under current scheme and discount rates. It provides

facility to the customers to give the order for the particular thing which user wants

to buy. The web site contains many products.

The main purpose of this website is to eliminate middlemen between the customer

and publisher and to provide all profits to the customers. As this system is online to

the customers, they home delivery of the required products at the effective prices

under one roof. The web site will have the facility to provide the membership by

signing in as a new user and will provide extra benefits such as giving discounts or

gifts to the users if they are member of the site by playing a little registration fee.

The project will have a login from, which will help the existing customer to log on

to the site and get benefits. This project is paid site project. With this website

efficiency is improved up tot large extent because it is easy for the user or the

buyer to purchase the product at reasonable cost without roaming here and there.

Further it will also contain the information that how many persons have visited the

site that will help to analyses the number of customer each day visiting our site.

Listing of the bank through which the payment can be made will also be given.

Payment mode will also be guided to the user so that shopping can be done easily.

On this web site customers can also send suggestions and complaints.

OBJECTIVES OF THE PROJECTThe project serves the following objectives:

The product are available online. One does not have to move from one store

to another in search of particular product.

After ordering the product the payment can be made easily through any

online payment method.

The cost of the item is less compared to when the item is purchased from

any shopping store because there is no middlemen between the publisher and

customer.

Transport cost is reduced to zero as one gets the item delivered at home

only.

SCOPE OF FUTURE APPLICATION

Today is the world of Information Technology. Neither any organization nor any

person can work efficiently without the use of Computers. We need computers in

almost all the fields today. Our Project “Online Shopping” is not only a project

which covers today’s inventory related aspects but it can be used effectively in

future as well. Nowadays, no. of shopping malls and other inventory dealing firms

are coming up in India many other projects are also in the pipeline. So this project

can help these firms and organizations work better

ASP.NET Introduction

ASP.NET is the latest version of Microsoft's Active Server Pages technology

(ASP). ASP.NET is a server side scripting technology that enables scripts

(embedded in web pages) to be executed by an Internet server.ASP.NET is a

Microsoft Technology ASP stands for Active Server Pages. ASP.NET is a program

that runs inside IIS.IIS (Internet Information Services) is Microsoft's Internet

server. IIS comes as a free component with Windows servers. IIS is also a part of

Windows 2000 and XP Professional.

ASP.NET is Not ASP:-ASP.NET is the next generation ASP, but it's not an

upgraded version of ASP. ASP.NET is an entirely new technology for server-side

scripting. It was written from the ground up and is not backward compatible with

classic ASP.You can read more about the differences between ASP and

ASP.NET,ASP.NET is the major part of the Microsoft's .NET Framework.

ASP.NET Work:-When a browser requests an HTML file, the server returns the

file. When a browser requests an ASP.NET file, IIS passes the request to the

ASP.NET engine on the server. The ASP.NET engine reads the file, line by line,

and executes the scripts in the file Finally, the ASP.NET file is returned to the

browser as plain HTML.

ASP+:-ASP+ is the same as ASP.NET.ASP+ is just an early name used by

Microsoft when they developed ASP.NET.

The Microsoft .NET Framework:-The .NET Framework is the infrastructure for

the Microsoft .NET platform. The .NET Framework is an environment for

building, deploying, and running Web applications and Web Services.Microsoft's

first server technology ASP (Active Server Pages), was a powerful and flexible

"programming language". But it was too code oriented. It was not an application

framework and not an enterprise development tool.The Microsoft .NET

Framework was developed to solve this problem. .NET Frameworks keywords:

Easier and quicker programming.

Reduced amount of code.

Declarative programming model.

Richer server control hierarchy with events.

Larger class library.

Better support for development tools.

The .NET Framework consists of 3 main parts:

Programming languages:

C#

Visual Basic (VB .NET)

J#

Server technologies and client technologies:

ASP .NET (Active Server Pages)

Windows Forms (Windows desktop solutions)

Compact Framework (PDA / Mobile solutions)

Development environments:

Visual Studio .NET (VS .NET)

Visual Web Developer

Master Pages:- ASP.NET didn't have a method for applying a consistent look and

feel for a whole web site.Master pages in ASP.NET 2.0 solves this problem.A

master page is a template for other pages, with shared layout and functionality. The

master page defines placeholders for content pages. The result page is a

combination (merge) of the master page and the content page.

Themes:- Themes is another feature of ASP.NET. Themes, or skins, allow

developers to create a customized look for web applications. Design goals for

ASP.NET themes:

Make it simple to customize the appearance of a site.

Allow themes to be applied to controls, pages, and entire sites.

Allow all visual elements to be customized.

Web Parts:- ASP.NET Web Parts can provide a consistent look for a site, while

still allowing user customization of style and content. New controls:

Zone controls - areas on a page where the content is consistent

Web part controls - content areas for each zone

Navigation:-ASP.NET has built-in navigation controls like

Site Maps

Dynamic HTML menus

Tree Views  

Security:-Security is very important for protecting confidential and personal

information. In ASP.NET the following controls has been added:

A Login control, which provides login functionality.

A Login Status control, to control the login status.

A Login Name control to display the current user name.

A Login View control, to provide different views depending on login status.

A Create User wizard, to allow creation of user accounts.

A Password Recovery control, to provide the "I forgot my password"

functionality.

Roles and Personalization:- Internet communities are growing very

popular.ASP.NET has personalization features for storing user details. This

provides an easy way to customize user (and user group) properties.

Internationalization:- Reaching people with different languages is important if

you want to reach a larger audience.ASP.NET has improved support for multiple

languages.

Data Access:- Many web sites are data driven, using databases or XML files as

data sources. With ASP.NET this involved code, and often the same code had to be

used over and over in different web pages. A key goal of ASP.NET was to ease the

use of data sources.ASP.NET has new data controls, removing much of the need

for programming and in-depth knowledge of data connections.

Mobility Support:-The problem with Mobile devices is screen size and display

capabilities. In ASP.NET, the Microsoft Mobile Internet Toolkit (MMIT) provided

this support. In ASP.NET, MMIT is no longer needed because mobile support is

built into all controls.

Images:- ASP.NET has new controls for handling images:

The Image Map control - image map support.

The Dynamic image control - image support for different browsers.

These controls are important for better image display on mobile devices, like

hand-held computers and cell phones.

Automatic Compilation;-ASP.NET provides automatic compilation. All files

within a directory will be compiled on the first run, including support for WSDL,

and XSD files.

Compiled Deployment (Installation) and Source Protection:- ASP.NET also

provides pre-compilation. An entire web site can be pre-compiled. This provides

an easy way to deploy (upload to a server) compiled applications, and because only

compiled files are deployed, the source code is protected.

Site Management:- ASP.NET has three new features for web site configuration

and management:

New local management console.

New programmable management functions (API).

New web-based management tool.

History

After the release of Internet Information Services 4.0 in 1997, Microsoft began

researching possibilities for a new web application model that would solve

common complaints about Active Server Pages, especially with regard to

separation of presentation and content and being able to write "clean" code. Mark

Anders, a manager on the IIS team, and Scott Guthrie, who had joined Microsoft in

1997 after graduating from Duke University, were tasked with determining what

that model would look like. The initial design was developed over the course of

two months by Anders and Guthrie, and Guthrie coded the initial prototypes during

the Christmas holidays in 1997.

The initial prototype was called "XSP"; Guthrie explained in a 2007 interview that,

"People would always ask what the X stood for. At the time it really didn't stand

for anything. XML started with that; XSLT started with that. Everything cool

seemed to start with an X, so that's what we originally named it." The initial

prototype of XSP was done using Java, but it was soon decided to build the new

platform on top of the Common Language Runtime (CLR), as it offered an object-

oriented programming environment, garbage collection and other features that

were seen as desirable features that Microsoft's Component Object Model platform

didn't support. Guthrie described this decision as a "huge risk", as the success of

their new web development platform would be tied to the success of the CLR,

which, like XSP, was still in the early stages of development, so much so that the

XSP team was the first team at Microsoft to target the CLR.With the move to the

Common Language Runtime, XSP was re-implemented in C# (known internally as

"Project Cool" but kept secret from the public), and renamed to ASP+, as by this

point the new platform was seen as being the successor to Active Server Pages, and

Jasleen Kaur

ONLINE SHOPPING

the intention was to provide an easy migration path for ASP developers.Mark

Anders first demonstrated ASP+ at the ASP Connections conference in Phoenix,

Arizona on May 2, 2000. Demonstrations to the wide public and initial beta release

of ASP+ (and the rest of the .NET Framework) came at the 2000 Professional

Developers Conference on July 11, 2000 in Orlando, Florida. During Bill Gates's

keynote presentation, Fujitsu demonstrated ASP+ being used in conjunction with

COBOL and support for a variety of other languages was announced, including

Microsoft's new Visual Basic .NET and C# languages, as well as Python and Perl

support by way of interoperability tools created by ActiveState.

Once the ".NET" branding was decided on in the second half of 2000, it was

decided to rename ASP+ to ASP.NET. Mark Anders explained on an appearance

on The MSDN Show that year that, "The .NET initiative is really about a number

of factors, it’s about delivering software as a service, it's about XML and web

services and really enhancing the Internet in terms of what it can do .... we really

wanted to bring its name more in line with the rest of the platform pieces that make

up the .NET framework."

After four years of development, and a series of beta releases in 2000 and 2001,

ASP.NET 1.0 was released on January 5, 2002 as part of version 1.0 of the .NET

Framework. Even prior to the release, dozens of books had been written about

ASP.NET, and Microsoft promoted it heavily as part of their platform for web

services. Guthrie became the product unit manager for ASP.NET, and development

continued apace, with version 1.1 being released on April 24, 2003 as a part of

Windows Server 2003. This release focused on improving ASP.NET's support for

mobile devices.

Performance

ASP.NET aims for performance benefits over other script-based technologies

(including Classic ASP) by compiling the server-side code to one or more DLL

files on the web server. This compilation happens automatically the first time a

page is requested (which means the developer need not perform a separate

compilation step for pages). This feature provides the ease of development offered

by scripting languages with the performance benefits of a compiled binary.

However, the compilation might cause a noticeable delay to the web user when the

newly-edited page is first requested from the web server.

The ASPX and other resource files are placed in a virtual host on an Internet

Information Services server (or other compatible ASP.NET servers; see Other

Implementations, below). The first time a client requests a page, the .NET

framework parses and compiles the file(s) into a .NET assembly and sends the

response; subsequent requests are served from the DLL files. By default ASP.NET

will compile the entire site in batches of 1000 files upon first request. If the

compilation delay is causing problems, the batch size or the compilation strategy

may be tweaked.Developers can also choose to pre-compile their code before

deployment, eliminating the need for just-in-time compilation in a production

environment.

ASP.NET compared to ASP classic

ASP.NET attempts to simplify developers' transition from Windows application

development to web development by offering the ability to build pages composed

of controls similar to a Windows user interface. A web control, such as a button or

label, functions in very much the same way as its Windows counterpart: code can

Jasleen Kaur

ONLINE SHOPPING

assign its properties and respond to its events. Controls know how to render

themselves: whereas Windows controls draw themselves to the screen, web

controls produce segments of HTML and JavaScript which form part of the

resulting page sent to the end-user's browser.ASP.NET encourages the programmer

to develop applications using an event-driven GUI model, rather than in

conventional web-scripting environments like ASP and PHP. The framework

attempts to combine existing technologies such as JavaScript with internal

components like "ViewState" to bring persistent (inter-request) state to the

inherently stateless web environment.

Other differences compared to ASP classic are:

1. Compiled code means applications run faster with more design-time errors

trapped at the development stage.

2. Significantly improved run-time error handling, making use of exception

handling using try-catch blocks.

3. Similar metaphors to Microsoft Windows applications such as controls and

events.

4. An extensive set of controls and class libraries allows the rapid building of

applications, plus user-defined controls allow commonly-used web

template, such as menus. Layout of these controls on a page is easier

because most of it can be done visually in most editors.

5. ASP.NET leverages the multi-language capabilities of the .NET Common

Language Runtime, allowing web pages to be coded in VB.NET, C#, J#,

Delphi.NET, Chrome etc.

6. Ability to cache the whole page or just parts of it to improve performance.

Jasleen Kaur

ONLINE SHOPPING

7. Ability to use the code-behind development model to separate business

logic from presentation.

8. If an ASP.NET application leaks memory, the ASP.NET runtime unloads

the AppDomain hosting the erring application and reloads the application

in a new AppDomain.

9. Session state in ASP.NET can be saved in a Microsoft SQL Server

database or in a separate process running on the same machine as the web

server or on a different machine. That way session values are not lost when

the web server is reset or the ASP.NET worker process is recycled.

10. Versions of ASP.NET prior to 2.0 were criticized for their lack of

standards compliance. The generated HTML and JavaScript sent to the

client browser would not always validate against W3C/ECMA standards.

In addition, the framework's browser detection feature sometimes

incorrectly identified web browsers other than Microsoft's own Internet

Explorer as "downlevel" and returned HTML/JavaScript to these clients

with some of the features removed, or sometimes crippled or broken.

However, in version 2.0, all controls generate valid HTML 4.0, XHTML

1.0 (the default) or XHTML 1.1 output, depending on the site

configuration. Detection of standards-compliant web browsers is more

robust and support for Cascading Style Sheets is more extensive.

11. Web Server Controls: these are controls introduced by ASP.NET for

providing the UI for the web form. These controls are state managed

controls and are WYSIWYG controls.

INTRODUCTION TO SQL SERVER 2005 SQL SERVER 2005 is a Microsoft Product that is a software used to

provide service that deals with the database.

SQL is a query language that is used to interact with the database.

It can be accessed by most programming languages.

Information stored in a SQL Server 2005 database hosted on a web server

can be accessed from anywhere in the world with a computer.

This makes it a good way to store information that needs the ability to

change over time, but also needs to be accessed over the net. Some examples

that can utilize SQL Server 2005 are a web message board or a customer's

shipping status.

SQL Server has some differences from Oracle 9i such as the Unique key

can have at most one null values here. It uses various stored procedures as a

compiled object.

SQL Server 2005 Express is the free version of the Microsoft SQL Server

2005 database.

It replaces MSDE (Microsoft SQL Server 2000 Desktop Engine), which was

based on Microsoft SQL Server 2000.

Organizations that have developed MSDE applications will find it easy to

move to SQL Server 2005 Express.

SQL Server 2005 Express includes the new SQL Server 2005 database

engine enhancements and a new graphical user interface (GUI) tool called

SQL Server 2005 Management Studio Express Edition.

SQL Server 2005 Express is integrated with Microsoft Visual Studio, which

facilitates the design and development of database applications.

Jasleen Kaur

ONLINE SHOPPING

Like MSDE, SQL Server 2005 Express is designed to provide an easy-to-use

database platform that can be freely distributed with your applications.

SQL Server 2005 Express has a number of important advantages over

MSDE, such as visual configuration tools, XML data support, and simplified

deployment of applications. These changes have resulted in a number of

important differences between SQL Server 2005 Express and MSDE.Some of these advantages are:

• Increased maximum database size

• No workload governor

• SQL Server 2005 Management Studio Express Edition

• CLR integration

• New data types

• User instance support

• Reporting Services

• SQL Service Broker

• Full text search

Why Visual Studio 2008 and SQL Server 2005?

Microsoft Visual Studio 2008 and SQL Server 2005 combine to be an easily

acceptable combination and are supported by all Operating Systems.

Microsoft Visual Studio 2008 is the Microsoft Software that can be easily

bounded with SQL Server 2005 as it is accompanied within the Visual

Studio2008 package.

In Visual Studio 2008, I am using Visual Basic, ASP.NET in my web

application.

Jasleen Kaur

Visual Studio 2008 works at the Front End and SQL Server 2005 at the

Back End .

Web Designing in ASP.NET, and coding through C# or VB and Connection

establishment with SQL Server 2005 for database access is much easier.

Both provide GUI environment.

Easily transported and stored.

.NET Framework has enabled us to develop a platform independent

SYSTEM STUDY

INVENTORY: all commercial organization such as factories, warehouses and

traders keep in a stock, either for their own serving machines. Material stocked for

future sale or consumption is called inventory.

The kind of inventory held by different organizations usually consist of:-

1. Raw materials and supplies inventory.

2. Production inventories.

3. Maintenance repair and operation inventories.

4. In process inventories.

5. Finished products inventories.

INVENTORY CONTROL:- the advent of modern industrialization has in its

wake highlighted a number of management problem an imported one of which is

cost reduction and cost control. Inventories are the assets of organizations and

represent investment. Since inventories are of indispensable use of the industry

there has to be some controls on them. Effective controlled inventories can

contribute sustention to a concerns profits.

Inventory control may be defined the planning, ordering and scheduling of

materialized in manufacturing process. It is possible to exercise control over three

types of inventories recognized by the accountant as the raw materials, work in

progress and finished goods.

It emerges from the definition given above that the inventory control is the system

devised and adopted for controlling investment in the inventory. It involves

inventory planning and decision making with regard to quantity time of purchase,

fixation of stock levels, maintenance of store records and controls exits neither the

material wait unduly long for men and machine and nor do they have to wait for

the material.

The game of inventory management aims to attain a healthy balance between cost

of inventory and cost of not having it. On one hand it might lead to our stocking as

is in the case of Govt. institution but on the other hand it could help to maintain

such least amount of stock level so that the demand is met just in time to meet

schedules.

IDENTIFICATION OF NEED:- the success of a largely depends upon hoe

accurately the problem is defined and investigated. Not until the problem is defined

and evaluated, should we think about the solutions.

LIMITATIONS:- though the existing system is working efficiently, still

introduction of computers will enhance the overall performance. before

computerization, the companies have to face many problems describe below:-

When the work is done manually, a number of registers need to be

maintained to keep records of the suppliers/customers, their reports etc. thus

a lot of paperwork is involved.

The data and information is redundant and scattered in various registers,

which results in non-synchronized procedure of collection, transmission and

processing of data.

Some accidental error in data entry may cost a lot of confusion and wastage

of time, since this data may be required later for computation and

assessment.

Inconsistency problems.

Security problems.

Jasleen Kaur

ONLINE SHOPPING

This project will rectify all such problems. The basic inventory control problem

therefore become of determine the following two:-

a) How much an order for material be placed?

b) How much should be produced at beginning of each time interval or what

quantity of item should be ordered at each time?

SALES AND SELLING

Both in purchasing and non-manufacturing concerns, selling function is involves,

beside manufacturing of purchasing goods, in order to perform this function

efficiently selling and distribution expense are incurred in all the concerns. Most of

these are included in direct costs.

The role aim if the business is to maximize profits but this is only possible by

reducing the cost of production or increasing the sales in the existing markets or by

entering new markets. No doubt the cost of production is reduce by increasing the

production but increase in sales is a must to meat the increase in output. In order to

increase the sales most of the firms are undertaking sales promotion activities but

they have to face stiff competition: under such circumstances, it become necessary

for a firm to incur selling and distribution expenses and some times they are so

heavy that they are even more than the manufacturing expenses. In some concerns

after sale service is provided for special products like radios, television,

refrigerators, washing machine and some special facilities and discounts are given

to wholesalers and retailers. Accounting and controls of selling and distribution

expense which are generally incurred after the production of goods has assumed an

increase importance in order to determine the cost of sales and profitability of each

job and product, control the selling and distribution cost, to fix price and formulae

sales price policy, to fix optimum sale levels and to make decision regarding sales

i.e. sales under different conditions markets regions and by different methods.

The accounting of selling distribution overhead requires three stage analysis:

1) Accounting to nature of objects of expenditure.

2) By function or cost center.

3) By products of cost units.

The control selling and distribution overhead is comparatively difficult

because of certain special features of such cost which requires a more

detailed and exacting analysis cost of the expenses s most of the expense are

incurred after the production is completed. The incidence of such overhead is

dependent upon various such as distance of market terms of sales an extent of

competition due to which it is not possible to fix standards. The main

problems which are in control of selling and distribution overhead costs are

as under:-

1) No controls over customer of competition is possible.

2) Sales capacity of the organization can’t be described properly.

3) There is no supervision of staff working outside and this requires

incentives schemes remunerating such as staff.

4) Original business may establish market price without reference to the cost

of production.

5) It is difficult to obtain market operation data.

Jasleen Kaur

ONLINE SHOPPING

6) It is difficult to as certain the capacity of the market.

7) the difference of making or not making is not clear.

Most of the items of the selling and distribution are in nature of policy costs and

are controllable at the lower levels of management.

Although price are more controlled by market management. This function is to

performed under normal circumstances, in times of competition, in times of

competition, in times of trade depression, in accepting additional orders of utilizing

idle capacity and finally, in exporting and exploring new markets.

In normal circumstances, the price fixed must cover total cost as otherwise profits

can’t be earned. It can also be fixed on the basis of marginal cost by adding a high

margin to marginal cost which may be sufficient to contribute towards fixed

expenses and profits. But under other circumstances products may have to be sold

price below total cost. If such a steps is necessary to meet the situation arising due

to competition, depression additional orders by utilizing spare capacity, exploring

new markets etc. thus in special circumstances, price may be the total and it should

be equal to the marginal cost plus a certain amount. The analysis of various matters

will be complete only when the actual profit and standard profit is fully analysis. It

is necessary to make an analysis of the sales variance to complete analysis of profit

variance because profit is the difference sales and costs. Thus in addition to the

analysis of cost variance and overhead cost variance i.e. material cost variance,

labor cost variance and overhead cost variance, an analysis the sales variance

should be made. Sales variance may be calculated in two different ways. These

may be computed so as to show the effect on profit or these made calculated to

show the effect on sales value.

PURCHASING

Purchasing is the most important function of the materials management. At the

moment an order is placed for the purchase of the material, a substantial part of the

company’s finance is committed which cash flow position of the company. Thus if

size of the business concern permits there should be a separate purchasing all types

of materials should be entrusted to this department.

Purchasing is not an end in itself: materials and suppliers are brought because they

are needed to be used. It is some time regarded merely as a service function

because the activities of purchasing have the primary function of implementing the

work of other departments by producing these products.

With changing conditions, the purchasing policy of today could be disastrous for

tomorrow. Continuous attention and a maximum flexibility are essential. These

changes must be recognized they should be anticipated and purchasing methods to

be develop to cope with them successfully.

Purchasing has required a state of dynamic management activity which includes:-

1) able administration.

2) Accurate forecasting.

3) Effective planning.

4) Developed capacity to organized.

5) Effective co-ordination.

6) Better controlling machinery.

7) Judicious timely decision.

Jasleen Kaur

ONLINE SHOPPING

Purchasing may be defined as a process of buying, learning a need, selecting a

supplier, negotiating a price, fixing terms for delivery and payment. Procurement is

a generic term, much broader than purchasing which includes purchasing and all

additional function connected with the classes of resources(people, material,

facilities and salvage operation. All the term procurement originates in the

governmental organization. It has been used in the segments of American industry

for many years procurement includes extraction from owned minus of forests,

cultivation of agricultural lands, manufactured in on plants and purchase.

Today’s purchasing agent is no longer the order placer of yeastier year. He is

instead a seeker one looking for the best value the market can offer to meet

company’s needs of the materials. Failures of purchasing policy adds to the cost of

production of ineffective selling techniques.

The ultimate object of purchasing function is the maximization of profits of

minimizing the cost of production. Purchasing objectives vary according to the

type of business and manufacturing activities.

What, when, how , how much, from whom and what price to buy are decision that

must to be made in purchasing department rightness of the decision determines

how well the responsibility is fulfilled. Strictly speaking they are not steps in

purchasing for the factors are so completely simultaneously. The purchasing policy

followed by an organization are based on the following principle of the

purchasing:-

1) Right quantity.

2) Right price.

3) Right source.

4) Right quality.

Jasleen Kaur

ONLINE SHOPPING

5) Right time.

6) Right place.

It is quite clear that purchasing is integral and essential part of business must mesh

into a unified whole if management is to fulfill its basic responsibility to optimize

enterprise profits. Each function of business must share in this responsibility.

INVENTORY TURNOVER RATIO

STORES:- There are many small items required in a manufacturing house for

proper maintenance of machines like cotton, blankets, thick cotton sheets, bed

sheets, towels etc. separate accounts are not opened for these instead one account

i.e. ‘STORES’ is opened and total stores consumed during a period are debited to

trading account. For calculating the value of stores consumed, following formula

may be used:-

Stores Consumed= Opening stock of stores + Purchasing stock of stores – Closing

stock of stores

STOCK OR INVENTORY TURNOVER RATIO:- This ratio measures how

many times the average stock is during the year. Promptness of the sale indicates

better performance of the business. It also shows efficiency of the concern.

Immediate sales of goods produced require further production which consequently

activates the production process and is responsible for rapid development of the

business. Higher inventory turnover ratio is always beneficial to the concern.

Lower inventory turnover ratio shows that the stock is blocked and not

immediately sol. It shows the poor performance of the business and inefficiency of

the management. The ratio measures the effectiveness of the stock policy of the

Jasleen Kaur

management. It should be the constant effort of the management to dispose of the

stock at the earliest.

The ratio establishes relationship between cost of goods sold and average stock.

Every business has to keep optimum quality of stock, so that production work may

be carried on smoothly. If the average inventory kept during the year is more

than ordinary requirement, the amount spent in its purchase will be

unnecessarily blocked and there will also be the problem of storing it. In

case, the average stock is lesser than the ordinary requirement, the

production work will suffer. It is always advisable to keep the required

quantity of the stock. This ratio is calculated as under:-

Stock turnover ratio= cost of goods sold/ average stock

Cost of goods sold is also known as the cost of sales and is calculated as

under:-

Cost of goods sold= opening stock + purchase + direct expenses – closing stock

Or

Cost of goods sold= net sales – gross profit.

Average stock= opening stock + closing stock/2

SYSTEM ANALYSIS

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

relationships within and outside the system. One should know, what should be

done to solve the problem? During analysis data are collected on available files,

decision points and transactions handled by the present system. The analysis

conducted resulted in the formation of the database relations and the different

attributes to be used by the back end tools. Data flow diagrams, interviews, on site

observations, and questionnaires are examples. The interview is a commonly used

tool in analysis. It requires special skills and sensitivity to the subjects being

interviewed. Bias in data collection and interpretation can be a problem.

Training, experience, and common sense are required for collection of the

information needed to do the analysis.

Once analysis is complete, the analyst has a firm understanding of what

is to be done. The next step is to decide how the problem might be solved. Thus in

systems design, we move from the logical to the physical aspects of the life cycle.

SYSTEM DEVELOPMENT LIFE CYCLE

Software development cannot happen in a single stage. For making a project we

need various stages of the system development life cycle. In this cycle, each stage

has its definite role, which is useful in the development of the system. Many

people may their part in the development of the system like system analyst,

programmer, designer and the user. The combination of all these people makes the

system successful.

The system analyst gives a development project meaning and direction. Analysis

means breaking a problem into successively manageable parts for individual study.

A candidate system approached after the analyst has a through understanding of

user’s need and problems. A candidate system means the newly developed system

designed to replace the existing system. It needs to recognize that a candidate

system has a life cycle.

The system development life cycle involve the following stages:

1. RECOGNIZATION OF NEED

2. FEASIBILITY STUDY

3. ANALYSIS

4. DESIGN

5. IMPLEMENTATION

6. POST IMPLEMENTATION

Following are the key questions that are needed to be taken in

consideration while developing a system:

RECOGNITION OF NEED - What is the problem?

One must know what the problem is before it can be solved. The basis for a

candidate system is the recognition of a need for improving an information system

or procedure. e.g. a supervisor may want to investigate the system flow in

purchasing or a bank president has been obtaining complaints about the long lines

in the drive-in. The need leads to preliminary survey or Initial Investigation to

determine whether an alternative system can solve the problem. It entails looking

into the duplication of efforts, bottlenecks, inefficient existing procedures, or

whether parts of the existing system would be candidate for computerization.

If the problem is serious enough, management may want to have

an analyst look at it. Such an assignment implies a commitment, especially if the

analyst is hired from the outside. In larger environment the analyst's first task is to

prepare a statement specifying the scope & objective of the problem. He/she then

reviews it with the user for accuracy. At this stage, only a rough estimate of the

development cost of the project may be reached. However an accurate cost of the

next phase-feasibility study can be produced.

Impetus for System ChangeThe idea for change originates in the environment or from within the firm.

Environment-based ideas originate from customers, vendors, government sources,

and the like. For example, new employment compensation regulations may make

it necessary to change the reporting procedure, format and contents of various

reports, as well as file structures. Customer complaints about the delivery schedule,

the experience of truck drivers, or the volume of orders to be delivered. When

Jasleen Kaur

ONLINE SHOPPING

investigated, each of these ideas may lead to a problem definition as a first step in

the software development life cycle process.

Ideas for change may also come from within the organization-top management, the

user, and the analyst. As an organization changes its operations or faces advances

in computer technology, someone within the organization may feel to update

existing applications or improve procedures.

Here are some examples:

An organization acquires another organization.

A local bank branches into the suburbs,

A department spends 80 percent of its budget in one month.

Two departments are doing essentially the same work, and each department

head insists the other department should be eliminated.

A request for a new form discloses the use if bootleg (unauthorized) forms.

User- originated ideas also prompt initial investigations. For example, a bank's

head teller has been noticing long customer lines in the lobby. He wants to know

whether they are due to computer's slow response to inquiries, the new teller's

limited training, or just a sudden increase in bank business. To what extent and

how quickly a user - originated idea is converted to a feasibility study depend on

several factors.

The risks and potential returns.

Management's bias toward the user.

Financial costs and the funds available for system work.

Priorities of other projects in the firm.

The persuasive ability of the user.

All these factors are crucial for a prompt response to a user request for change. A

system analyst is in a unique position to detect and even recommend change.

Jasleen Kaur

ONLINE SHOPPING

Experience and previous involvement in the user's area of operations make him /

her convenient resource for ideas. The role and status of the analyst as a

professional add credibility to the suggestions made.

FEASIBILITY STUDY

The objective of Initial Investigation is to determine whether the request is valid

and feasible before a recommendation is reached to do nothing, improve, or

modify the existing system, or build a new one.

Depending on the results of the initial investigation, the survey is expanded to a

more detailed feasibility study. A feasibility study is a test of a system proposal

according to its workability, impact on the organization, ability to meet user needs,

and effective use of resources. It focuses on three major things:

1. What are the user's demonstrable needs and how does a candidate system

meet them?

2. What resources are available for given candidate systems?

3. What are the likely impacts of the candidate system on the organization?

THERE ARE MAJOR CHARACTERSTICS TO BE TAKEN INTO

ACCOUNT

Economic feasibility

Technical feasibility

Behavioral feasibility

Economic FeasibilityEconomic analysis is the most frequently used method for evaluating the

effectiveness of a candidate system. A procedure of cost/benefit analysis is applied

to determine the savings and benefits that are expected from the candidate system

Jasleen Kaur

ONLINE SHOPPING

and then compare them with the costs. If benefits outweigh the costs, then the

decision is made to design and implement the system. Otherwise, further

justification or alterations in the propose system will have to be made if it is to

have a chance of being approved. This is an ongoing effort that improves in

accuracy at each phase of the system life cycle.

Social Feasibility

It is important to study the social implications when a new product or system is

introduced. People are inherently resistant to change and computers have been

known to facilitate change. An estimate should be made of how strong a reaction

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

common that computer installation results in turnover, transfers, retraining and

changes in the employee’s job status. Therefore, it is undesirable that the

introduction of the candidate system requires special effect to educate, sell, and

train the staff on new ways of conducting business. When we explained our system

to users, they gave a good response.

Behavioral Feasibility

People are inherently resistant to change, and computers have be known to

facilitate change .it is common knowledge that the computer installation has

something to with turnover, transfer, retraining and changes in the employee job

status therefore it is understandable that the introduction of the candidate system

requires special effort to educate and train the staff on new ways of conducting

business

Points that the user staff rose against the new system.

Jasleen Kaur

ONLINE SHOPPING

1) Difficult training would have to be undertaken at personal costs.

2) Change in job status, and may be demotion if found not qualified for the job.

3) Difficulties in change the old record.

4) Transfer of employees to less relevant job station.

5) Difficult and time consuming requires if system failure occurs during the working

hours.

6) Loss of time and working hours if the system is not repaired on the time.

The user staff that had to directly work on the new system gave all the limitation.

or the apprehensions that are listed above. They feared that the new system would

result in the demotions or they will be out of their jobs.

Technical FeasibilityIt involves determining whether or not a system can actually be constructed to

solve the problem at hand. Technical feasibility centers on the existing computer

system (hardware, software) etc. and to what extent it can support the proposed

system. System developed by us is technically feasible because no system was

previously running on their system as he has purchased a new system. Our system

would be easy to use as it is user friendly to a person who knows simple English

can easily use it effectively and it is capable of fulfilling their requirements about

the production, sales, purchase, stock control of products and employee

information.

The various issues considered for the technical feasibility are:

Technical guaranties of accuracy, reliability, ease of access and data

security.

Usefulness in panning purposes.

Proposed system and component provide adequate responses to inquiries.

Comprehensive and full proof interdependence.

Data flow diagram

Data flow diagram example

Data flow diagram Yourdon and Coad notation

Data flow diagram (DFD) is a graphical representation of the "flow" of data

through an information system. A data flow diagram can also be used for the

visualization of data processing (structured design).

Overview

It is common practice for a designer to draw a context-level DFD first which

shows the interaction between the system and outside entities. The DFD is

designed to show how a system is divided into smaller portions and to highlight the

flow of data between those parts. This context-level DFD is then "exploded" to

Jasleen Kaur

ONLINE SHOPPING

show more detail of the system being modeled. Data flow diagrams were invented

by Larry Constantine, the original developer of structured design, based on Martin

and Estrin's "data flow graph" model of computation.

Data flow diagrams (DFDs) are one of the three essential perspectives of

Structured Systems Analysis and Design Method SSADM. The sponsor of a

project and the end users will need to be briefed and consulted throughout all

stages of a system's evolution. With a dataflow diagram, users are able to visualize

how the system will operate, what the system will accomplish, and how the system

will be implemented. The old system's dataflow diagrams can be drawn up and

compared with the new system's dataflow diagrams to draw comparisons to

implement a more efficient system. Dataflow diagrams can be used to provide the

end user with a physical idea of where the data they input ultimately has an effect

upon the structure of the whole system from order to dispatch to restock. How any

system is developed can be determined through a dataflow diagram.

Developing a DFD helps in identifying the transaction data in the data model.

There are different notations to draw data flow diagrams, defining different visual

representations for processes, data stores, dataflow, and external entities.

Developing a DFDElements of a DFD

There are 4 key elements in a Data Flow diagram; Processes, Data Flows, Data

Stores & External entities and each element is drawn differently. Another

important element which is typically marked with dashed lines is Feedback and

Control Data.

Process entity

Jasleen Kaur

ONLINE SHOPPING

The "Process entity" identifies a process taking place, it must have at least one

input and output. A process with no input is known as a "miracle process" and one

with no output is a "black hole process".

Both "miracle" and "black hole" processes are strong indicators that the DFD is

missing a connection between processes and should be re-evaluated. Each process

has the following :

1. A Number

2. A Name (verb phrase)

3. A Description

4. At least one input

5. At least one output

Data flow entity

The "Data Flow entity" identifies the flow of data between processes, data stores &

external entities. A data flow cannot connect an external entity to a data source; at

least one connection must be with a process. There are also "physical" flows, i.e.

those that use a physical medium, like a membership card. Each data flow has the

following:

1. A Name (Noun)

2. A Description

3. One or more connections to a process.

4. Data Store entity

The "Data Store entity" identifies stores of data, both manual and electronic.

Electronic or "digital" stores are identified by the letter D, and manual filing

systems by the letter M, e.g. D1 could be a MySQL database, and M4 could be a

filing cabinet. Each data store has the following:

Jasleen Kaur

ONLINE SHOPPING

1. A Number

2. A Name

3. A Description

4. One or more output data flows.

External entity

The "External Entity" identifies external entities which interacts with the system,

usually clients but can be within the same organization. Examples of an external

entity include customers, suppliers, management, certification agencies and

competitors. Multiple existences of the same entity, e.g. the same doctor shown

twice on the same diagram, can be identified by a horizontal line in the top left

corner of the symbol. Each external entity has the following:

1. A Name (Noun)

2. A Description

3. The Feedback and Control data

The "Feedback and Control data" identifies a special purpose. Only the first four

elements are needed to create a data flow diagram (DFD).

TESTING

Testing is the major quality control measure used during software development.

Its basic function is to detect errors in the software. During requirements analysis

and design, the output is a document that is usually textual and no executable.

After the coding phase, computer programs are available that can be executed for

testing purposes. This implies that testing not only has to uncover errors introduced

during coding, but also errors introduced during previous phases. Thus, the goal of

testing is to uncover the requirement, design, and coding errors in the programs.

Testing is extremely critical and time-consuming activity. It requires proper

planning of the overall testing process. Frequently the testing process starts with a

test plan that identifies all the testing-related activities that must be performed and

specifies the schedule, allocates the resources and specifies guidelines for testing.

The test plan specifies conditions that should be tested different units to be tested

and the manner in which the modules will be integrated together.

Different types of Testing:

UNIT TESTING : The starting point of testing is Unit Testing. In this, a

module is tested separately and is often performed by the coder himself

simultaneously along with the coding of the module. The purpose of unit testing

is to exercise the different parts of the module code to detect errors.

INTEGRATION TESTING : After Unit testing, the modules are

gradually integrated into subsystems, which are then integrated to eventually

from the entire system. During integration of modules, integration testing is

performed to detect errors by focusing on testing the interconnection between

modules.

SYSTEM TESTING : After the system is put together, system testing is

performed. Here the system is tested against the system requirements to see if

all the requirements are met and if the system performs as specified by the

requirements. System testing is a critical process that can consume more than

fifty percent of the development time.

ACCEPTANCE TESTING : Acceptance testing is performed to

demonstrate to the client, on real-file data of the client, the operation of the

system. Once the above testing is successful, the system group tests the

developed prototype of the project and their best suggestions are incorporated in

the prototype to form the overall system.

Following two strategies of software testing adopted for the new system that is

as follows:

1. CODE TESTING:- Code Testing has been carried out to see the correctness

of the logic involved and the correctness of the modules. Tests are conducted based

upon sample data and actual data. All the modules are checked separately for

assuring the correctness and accuracy in all calculation.

2. SPECIFICATION TESTING:- It examines that the specification starting

what the program should do and how it should perform under various conditions,

this testing is better strategy since it focuses on the way software is expected to

work. The testing was started from the bottom most modules and carried through

the modules at the upper level, the amount of coupling and cohesion is high in the

project

In this way, the software has been tested to yield appropriate and efficient results.

IMPLEMENTATION & MAINTAINANCE

The project having passed through all phases and now is ready for implementation

phase. Information on personal, money, hardware facilities and their estimated

costs have been calculated. The user needs not to be given any special training

about the programming or the system internal work. Even if he wants any change

to the previous records, he has not to interact with an interactive mode with

complex syntax. A screen has been provided for this purpose, which offers all

facilities to deal with software with very simple way. Hence a rather complex

looking task has been simplified. System testing has been carried out to check the

readiness and accuracy of the system to access update and retrieve data from files.

But work is not finished here because when the installation phase is completed and

the user staff has been trained to the change created by the system, evaluation and

maintenance of hardware and software. The important of maintenance is to

continue to bring the new system to standards.

The users are also provided with a report to assist in using the system. As the users

goes through the report he is made aware of what the past system was what is new

system an dhow is going to work. Specifications and details of operation

performed are given in system manual, which is an overview of the whole system.

The detail of how the system is to be performed. View of screen and report helps

the users to understand the system more quickly

and interactively. The system overview helps the user to get acquainted with what

the system is, what is composed of, how it works, what are the program errors

occurrence, how can they be corrected and above all how the system can be

utilized. The system manual also provides the inner view of the steps, which were

undertaken to construct the system, or the approaches followed to solve the

existing problem and deals with error conditions.

One of the essentials of the system implementation is availability of the user

feedback. The user feedback also helps us to know the system functioning. The

user was also very helpful to me during this phase as he self explained he requires

details about what changes.
