CHAPTER 1
INTRODUCTION
1.1.
Project Overview and Purposes
Comparison Shopping Site System is a web based application site that collects
information of the products from different shopping sites, and serves these information to the
users. So the users can find products very fast and easier with using our comparison shop site
system instead of investigating lots of shopping sites. Comparison shopping site system is
composed of two main parts. One of them is crawling part that visits the shopping sites,
gathers information about products and store them into database. Other part is front-end part
that serves information to the customers.
The main purpose of the project is to help the customers to find and buy products by
comparing lots of products from different shopping sites. It allows a smart searching in order
to increase the luck of finding products that are searched by user.
The other purpose of the projects is comparing the products by their prices, in order to
help the users to find the cheapest product.
1.2.
Scope of Project
This system can be used by everyone who wants to make an online shopping.
Generally people can use this system to compare a product in different shopping sites.
1.3.
Success Criteria of Project
Two main criteria that make this system successful are to;
1. Provide time saving for customers to find information of products from thousands of
shopping sites instead of visiting one by one.
2. Provide money saving for customers to compare the prices of products from different
shopping sites.

CHAPTER 2
BACKGROUND AND MOTIVATION
From the late 1990s, the range of information, products, and services available on the
internet grew massively. At the same time, the popularity of the Internet also grew at a
phenomenal rate. So, the internet became very beneficial platform in terms of making life
easy. Online shopping is one aspect of internet that makes life easy and convenience. Online
shopping is important because it offers buyers convenience that has never before been
achievable. The technology that is now available allows customers to shop on the internet 24
hours a day and seven days a week, without having to leave their homes or offices. Shoppers
are provided with an abundance of merchant sites where almost any goods on earth can be
bought. Consumers can also compare prices from a variety of different retailers with greater
ease, compared to them physically going to shop in a built shopping centre to check prices.
Nowadays, there is a new concept that is more popular that online shopping sites are
Comparison Shopping Sites. The mission of these kinds of sites is to help consumers
anywhere use the power of information to easily find, compare and buy anything online – in
less time and for the best price.
There are some problems on comparison shopping sites. The most important problem
is that to gather product information into database of comparison sites and update the database
regularly. Programmers produce different systems in order to solve this problem. One kind of
this system is called web crawler. Web crawler is a program that browses web pages and
filters needed information from these pages. Web crawlers are the core part of the searching
process.

PROPOSED SYSTEM
3.1. Project Overview
Comparison Shopping Site System is a web based application site that collects
information of the products from different shopping sites, and serves these information to the
users. So the users can find products very fast and easier with using our comparison shop site
system instead of investigating lots of shopping sites. Comparison shopping site system is
composed of two main parts. One of them is crawling part that visits the shopping sites,
gathers information about products and store them into database. Other part is front-end part
that serves information to the customers.
3.2. Functional Requirements
3.2.1. Searching A Product From The Web Site
Searching a product from indirim.com is very simple process for users. In the search
panel, users will enter search key into the textbox; the search process will start, after pressing
the “ARA” button.
Figure 3.2.1Main Page

3.2.2. Sorting Searched Products
User will sort products in terms of product names and product prices. It is also very
simple process for users. There are two sorting links; “ürün” and “fiyat”. User will click one
of sorting links and sorting process will be automatically done by system.
The products are placed unsorted after an search. When user clicks one of the sorting
links, the system will sort products by ascending order. After clinking the link second time,
the system sorts products by descending order automatically.
Figure 3.2.2 Sorting Searched Products
4
3.2.3. Listing Products
Twenty products are shown per page. User will check all products page by page by
selecting page number from the bottom menu of the web site.
Figure 3.2.3Listing Products
5
3.2.4. Narrowing Search Results
User will narrow search results in terms of price interval, product category, online
seller sites. There are 2 menu groups left side of the page for this process. The system allows
multiple narrowing criteria. For example, the user can narrow search of prices between 20
YTL and 300 YTL, after he/she narrowed the search results he/she can also filter an specific
online seller site like “alisveris.com”. So, the results contain the price between 20 YTL and
300 YTL and only from “alişveris.com”.
Figure 3.2.4 Narrowing Search Results

CHAPTER 6
GLOSSARY
Web Crawler: A web crawler (also known as a web spider or web robot) is a program or
automated script which browses the World Wide Web in a methodical, automated manner.
Many sites, in particular search engines, use spider as a means of providing up-to-date data.
Web crawlers are mainly used to create a copy of all the visited pages for later processing by
a search engine that will index the downloaded pages to provide fast searches. Crawlers can
also be used for automating maintenance tasks on a website, such as checking links or
validating HTML code. Also, crawlers can be used to gather specific types of information
from Web pages, such as harvesting e-mail addresses (usually for spam).
PHP: PHP is a reflective programming language originally designed for producing dynamic
web pages. PHP is used mainly in server-side scripting, but can be used from a command line
interface or in standalone graphical applications. PHP is a widely-used general-purpose
scripting language that is especially suited for Web development and can be embedded into
HTML. PHP generally runs on a web server, taking PHP code as its input and creating Web
pages as output.
MySQL: MySQL is a multithreaded, multi-user SQL database management system. MySQL
is popular for web applications. Its popularity for use with web applications is closely tied to
the popularity of PHP.
PHPEdit: PHPEdit is a commercial IDE developed by WaterProof SARL. It is written in
Delphi and runs on the Microsoft Windows operating system, and is designed mainly for the
PHP language, but supports many other languages such as CSS, HTML, JavaScript, INI,
PHPEditScript, PHP, PlainText, SQL, XML, and XSLT.
