ABSTRACT

The business-to-consumer aspect of electronic commerce (e-commerce) is

the most visible business use of the World Wide Web. The primary goal of an e-

commerce site is to sell goods and services online.

This project deals with developing an e-commerce website for Online Pizza

Hut Shopping. It provides the user with a catalog of different Pizzas available for

purchase in the store.

In order to facilitate online purchase a shopping cart is provided to the user.

The system is implemented using a 3-tier approach, with a backend database, a

middle tier of Microsoft Internet Information Services (IIS) and ASP.NET, and a web

browser as the front end client.

In order to develop an e-commerce website, a number of Technologies must

be studied and understood. These include multi-tiered architecture, server and client

side scripting techniques, implementation technologies such as ASP.NET,

programming language (such as vb) and relational databases (such as SQL Server

2005).

This is a project with the objective to develop a basic website where a

consumer is provided with a shopping cart application and also to know about the

technologies used to develop such an application.

This document will discuss each of the underlying technologies to create and

implement an e-commerce website.

1. Introduction of the Project

E-commerce is fast gaining ground as an accepted and used business

paradigm. More and more business houses are implementing web sites providing

functionality for performing commercial transactions over the web. It is reasonable

to say that the process of shopping on the web is becoming commonplace.

The objective of this project is to develop a general purpose e-commerce

store where any product (such as Veg Pizza and Non-Veg Pizza) can be bought from

the comfort of home through the Internet.

“www.PizzaHut.com” is a virtual store on the Internet where customers can

browse the catalog and select products of interest. The selected items may be

collected in a shopping cart.

At checkout time, the items in the shopping cart will be presented as an

order. At that time, more information will be needed to complete the transaction.

The customer will be asked to fill or select a shipping address, a shipping option, and

payment information such as credit card number. An e- mail notification is sent to

the customer as soon as the order is placed.

3.1 Gantt Chart A Gantt chart is a horizontal bar chart developed as a Production control in 1917 by Henry l. Gantt, an American engineer and social scientist. Frequently used in project management, a Gantt chart provides an graphical illustration of scheduling of the project plan, coordinate and track specific task in the project.

Grants chart may be a simple version created on the graph paper or complex automated version created using project management application such as Microsoft project or excel.

A Gantt chart is constructed in a horizontal axis representing the total time span of the project, broken down into increments and vertical axis representing task that make the project. Horizontal bars of varying length represent sequence, time span of the each task in the project.

5.1 Introduction

The purpose of this document is to provide an architectural

design for the Online Pizza Hut Shop. The design will show the presentation tier, the

middle tier consisting of classes, sequence diagrams, and the data tier consisting of

the database design diagram.

5.2 Architecture

Three-tier (layer) is a client-server architecture in which the user

interface, business process (business rules) and data storage and data access are

developed and maintained as independent modules or most often on separate

platforms.

The Architecture of Online Shopping of Software & E-Books is

based on three-tier architecture. The three logical tiers are

Presentation Tier - ASP.NET Web forms, ASP.NET User

Controls, ASP.NET Master Pages.

Business or Middle Tier – vb classes.

Data Tier – Database

1) Presentation Tier: - It is responsible for displaying the contents to the user.

2) Business Tier: - It communicates between Presentation Tier and Data Tier.

For Example,

Receiving the search request for the product and passing it to the

database and submitting the results back to presentation tier for

display.

Displaying the cart empty message when there is no product in the

shopping cart.

It is the main component of the website since it is responsible for

handling the overall logic.

3) Data Tier: - It is responsible for storing the product information, transactions

of the customer and shopping cart products. It is also responsible handling

the requests from the business tier and using stored procedures passing the

result back.

Fig. below shows the model of three-tier architecture.

The main reason for considering three-tier architecture for the Online

Pizza Hut Shop is as follows:

Flexibility:

• Management of data is independent from the physical storage support,

• Maintenance of the business logic is easier,

• Migration to new graphical environments is faster.

• If there is a minor change in the business logic, we don’t have to install the entire

system in individual user’s PCs.

Reusability:

• Reusability of business logic is greater for the presentation layer. As this

Component is developed and tested, we can use it in any other project and would be

helpful for future use.

Team Work:

• Team work is optimized.

Security:

• More secured architecture since the client cannot access the database directly.

5.2.1. Presentation Tier

The presentation tier for the Online Book Store is ASP.NET Web

Forms with User Controls. The presentation tier takes care of the user interaction

and the visual part of the website. The Visual Studio .NET IDE will be used to create

the Web forms. It uses code behind code, where the code for each ASPX page is

encapsulated into a separate file.

The various Web forms used by Users are listed below.

ASP.NET Web Forms Purpose

Default.aspx This web page is used to browse the entire website and also displays different categories, offers available

Aboutus.aspx The Web page displays information’s about the Pizza Hut.

Contactus.aspx The Web page is the display address to contact us.

Feedbackform.aspx The Web page is to feed back us about our service and query.

Registration.aspx The Web page where a new user can create a user account.

SuccesfullyRegistered.aspx The Web page for confirming successful registration.

UnSuccesfullyRegistered.aspx The Web page is not successful registration & says please try again.

Testing Software testing is a process of running with intent of finding errors

in software. Software testing assures the quality of software and represents final

review of other phases of software like specification, design, code generation etc.

6.1 Unit Testing

Unit testing emphasizes the verification effort on the smallest unit of

software design i.e.; a software component or module. Unit testing is a dynamic

method for verification, where program is actually compiled and executed. Unit

testing is performed in parallel with the coding phase. Unit testing tests units or

modules not the whole software.

I have tested each view/module of the application individually. As the

modules were built up testing was carried out simultaneously, tracking out each and

every kind of input and checking the corresponding output until module is working

correctly.

The functionality of the modules was also tested as separate units.

Each of the three modules was tested as separate units. In each module all the

functionalities were tested in isolation.

In the Shop Products Module when a product has been added to cart it has been

made sure that if the item already exists in the shopping cart then the quantity is

increased by one else a new item is created in the shopping cart.

Also the state of the system after a product has been dragged in to

the shopping cart is same as the state of the system if it was added by clicking the

add to cart button.

In the Product Description Module it has been tested that all the

images are displayed properly. Users can add review and the as soon as a user adds a

review it is updated in the view customer review tab.

It has been checked to see if the whole page refreshes or a partial

page update happens when a user writes a review.

In the Cart Details it has been tested that when a user edits a quantity

or removes a product from the cart, the total price is updated accordingly. It has

been checked to see if the whole page refreshes or a partial page update happens

when a user edits the cart.

Visual Studio 2005 has in built support for testing the application. The

unit testing can be done using visual studio 2005 without the need of any external

application.

Various methods have been created for the purpose of unit testing.

Test cases are automatically generated for these methods. The tests run under the

ASP.NET context which means settings from Web.config file are automatically picked

up once the test case starts running.

Methods were written to retrieve all the manufacturers from the

database, strings that match a certain search term, products that match certain filter

criteria, all images that belong to a particular product etc. Unit test cases were

automatically generated for these methods and it can be seen in figure 6.1 that the

tests have passed.

6.2 Integration Testing

In integration testing a system consisting of different modules is

tested for problems arising from component interaction. Integration testing should

be developed from the system specification.

Firstly, a minimum configuration must be integrated and tested. In

my project I have done integration testing in a bottom up fashion i.e. in this project I

have started construction and testing with atomic modules.

After unit testing the modules are integrated one by one and then

tested the system for problems arising from component interaction.

6.3 Validation Testing

It provides final assurances that software meets all functional,

behavioral & performance requirement. Black box testing techniques are used.

There are three main components

- Validation test criteria (no. in place of no. & char in place of char)

- Configuration review (to ensure the completeness of s/w configuration.)

- Alpha & Beta testing-Alpha testing is done at developer’s site i.e. at home & Beta

testing once it is deployed. Since I have not deployed my application, I could not do

the Beta testing.

Test Cases- I have used a number of test cases for testing the product. There were

different cases for which different inputs were used to check whether desired output

is produced or not.

1. Addition of a new product to the cart should create a new row in the shopping

cart.

2. Addition of an existing product to the cart has to update the quantity of the

product.

3. Any changes to items in the cart have to update the summary correctly.

4. Because same page is inserting data into more than one table in the database

atomicity of the transaction is tested.

6.4 White Box Testing

In white box testing knowing the internal working of the product,

tests can be conducted to ensure that internal operations are performed according

to specification and all internal components have been adequately exercised.

In white box testing logical path through the software are tested by

providing test cases that exercise specific sets of conditions and loops.

Using white-box testing software developer can derive test case that

• Guarantee that all independent paths within a module have been exercised at least

once.

• Exercise all logical decisions on their true and false side.

• Exercise all loops at their boundaries and within their operational bound.

• Exercise internal data structure to ensure their validity.

At every stage of project development I have tested the logics of the

program by supplying the invalid inputs and generating the respective error

messages. All the loops and conditional statements are tested to the boundary

conditions and validated properly.

Limitation & future Enhancements

7.1 Limitations

This application does not have a built in check out process. An

external checkout package has to be integrated in to this application. Also users

cannot save the shopping carts so that they can access later i.e. they cannot create

wish lists which they can access later.

This application does not have features by which user can set price

ranges for products and receive alerts once the price reaches the particular range.

7.2 Future Enhancements

The following things can be done in future.

• The current system can be extended to allow the users to save products in to wish

list.

• The users could subscribe for price alerts which would enable them to receive

messages when price for products fall below a particular level.

• The current system is confined only to the shopping cart process. It uses third Party

for Check out Process to Complete. It can be extended to have an easy to use check

out process.

• Users can have multiple shipping and billing information saved. During

Checkout they can use the drag and drop feature to select shipping and billing

information.

Conclusions

The ‘Online Pizza Hut Shop’ is designed to provide a web based

application that would make searching, viewing and selection of a product easier.

The search engine provides an easy and convenient way to search for

products where a user can Search for a product interactively and the search engine

would refine the products available based on the user’s input.

The user can then view the complete specification of each product.

They can also view the product reviews and also write their own reviews.

Use of Ajax components would make the application interactive and

prevents annoying post backs. Its drag and drop feature would make it easy to use.
