INTRODUCTION
Going online shopping is a process by which consumers go to internet in order to buy products. An online shop, e-shop, internet shop, web shop evokes the physical analogy of buying products or services at a shopping mall. When an Online shopper has an initial good experience with a certain website, sixty percent of the time they will return to that website to buy more. Books are one of the things bought most online. Cosmetics, nutrition products, and groceries are increasingly being purchased online.
In our project, mainly stress has been put to keep the online customers as much satisfied as possible. There are two modules in the system, one for the Administrator and another for the Customers. The interfaces, for both the entities have been kept too simple to understand. Administrators have the privileges regarding Adding a product, updating the product details or removing a product. On the other hand, Customers can Buy a product, or Edit their account details.
As far as Security is considered, Customers cannot enter into the Administrator’s area, or Administrators cannot enter into a Customer’s account. Also, only registered customers are allowed to do the shopping, so that no anonymous product order is generated. In case, a user gives a fraud Credit Card No. or CRN No. , then, in that case, they won’t be able to do the shopping, because, after 3 chances, the customer gets automatically logged out. If a user does not have an account, then they are allowed to create a new account. No, shopping can be done without doing the payments….

Hardware And Software Requirements
The System is compatible to run on any kind of hardware, regarding chipsets, motherboard, etc. As far as software requirement is considered, the system requires Windows 98 / 2000 / XP / Vista. Also the system requires a minimum of .NET Framework 2.0 installed on the computer. The system also requires a Web-Browser, because the system is made to run online.
Once the above requirements are confirmed, then the system can run fluently on the computer.
Database Design
The System consists of a single Database named as Shopping_cart
There are four tables under the Shopping_cart:
Product ID , Name, Category, Product_type, Price, Stock, Description
Customer Uname, Cname, Address, Email, Phno
User Uname ,Password , Type
AccountInvoiceno , Product_id , Uname , Transeation_date , Name_of_item ,Total_price , Discount
6 | P a g e
Product table:
product_id varchar(5) Not null
product_name varchar(30)
category varchar(30)
product_type varchar(30)
price float
stock int
description varchar(50)
customer table:
uname varchar(20) Not null
cname varchar(30)
address varchar(60)
email varchar(50)
phno varchar(50)
[User] table:
uname varchar(20) Not null
password varchar(12)
type varchar(50)
Accounts table:
invoice_no varchar(50)
product_id varchar(50)
uname varchar(50)
date_of_transaction varchar(50)
price float
no_of_items int
total_price float
discount int
id int Not null

User Interface Design
The system consists of two modules :
ADMINISTRATOR
It consists of a webform AddProduct, where a new product can added, updated, or deleted.
CUSTOMER
It consists of webforms NewAcc_Form, EditAccount, Authentication, Catalog, ProductReceipt.
NewAcc_Form
It is used to allow new customers to make a new account, by giving their personal as well as their account details.
EditAccount
It is used to allow a registered customer to edit their account details, regarding their passwords, credit card details, etc.
Authentication
It is used to authenticate the credit card details before conforming any kind of shopping.
Catalog
It is used to allow the registered customers to select the items to be shopped for, from the list of the products available in the web store, by adding the selected products to their basket. The customers can also see the subtotals along with the grand total.
ProductReceiptIt is used to get the final receipt of the items for which the shopping has been done.

Application Architecture
The system has a 3-tier architecture, which are User Interface Layer (UIL) , Business Logic Layer (BLL) and Database Application Layer (DAL).
User Interface Layer consists of only the Webforms.
Business Logic Layer consists of two classes; Customer, and Product.
Customer consists of following methods :
logup ( ) :
It takes the new customer’s details as input & passes those details to the DAL.
Login( ):
It checks the registered user’s username against the corresponding password and allows only authenticated users to proceed for shopping.
checkcreditcard( ) :
It checks the credit card details of the corresponding logged on customer against his credit card details. The customer can proceed for shopping, only when the authentication has been done.
Updateprofile ( ):
It updates the personal account details of the logged on customer by bringing changes to account made by the customer.
Product consists of following methods :
getdataProduct( ) :
It fetches the details of the Product from DAL and then passes it on to the User Interface.
AddProduct( ) :
It passes the details of the new product to be added in the database of the Products to the DAL.
43 | P a g e
Data Access Layer consists of following methods :
getpassword( ) :
It returns the username and password of the requested user to BLL.
addproduct( ) :
It adds the details of the new Product to the product database.
getCrnno( ) :
It retrieves the credit card no. and CRN no. of a particular customer from the customer database and returns it to the BLL.
addCustomer( ) :
It adds the details of the new customer to the customer database.
getdataproduct( ) :
It returns the details of the required product to the BLL.
getdataCustomer( ) :
It retrieves the details of customers in the customer database.
updateProfile ( ) :
It edits the account details of the required customer.
Coding of Business Logic Layer (BLL ) :
The BLL have two classes:
Product Customer

Future Enhancements The system is compatible of many enhancements which could have been
done but could not be completed due to some unavoidable reasons. Some of the facilities which could have been introduced are as follows.
There can be many administrators for the present Webstore, though it has been designed to work for only one administrator.
As a measure of security to the credit card details, a firewall could be designed which could prevent those details from leaking outside and falling into unsafe hands.
Before making a new account, the account details given by the customer must be confirmed online by the banks under which the customer bears an account.
Any registered customer won’t be able to buy any products if he provides the wrong account details more than 3 times.
Administrator can see the total shopping done by all the customers for a given particular date.
VALIDATION Every table has a primary key, so no chance of duplicate value. There is some restriction for every transaction action, so if some action or transaction violates that restriction it cannot be successful. People can get their required data about the products very easily and very fast.
