Online Shopping Cart System (6 Copies)

8/7/2019 Online Shopping Cart System (6 Copies)

1/35

Introduction

The project was all about developing a web application for maintaining online

shopping. The web application should be accessed from anywhere in the world through

Internet where visitors can create their account and become a customer. They can purchase

goods available in the online store by paying through credit card. There is an administrator

who monitors the website activity and adds, updates or removes product items as and when

required.

Problem Definition:

These days the importance of online shopping has increased significantly. Spending

hours for going to the shop and choosing the goods to buy is not always possible for

everyone. Facing the crowd is also a tough job for especially the senior citizens. Often people

do not get the world class goods in their locality. There are many more drawbacks of

conventional shopping procedure.

Proposed System:

In order to overcome these drawbacks, online shopping is a very convenient

alternative. We are designing a system that will facilitate the customers to review the

products, conveniently choose the required one and purchase them. The customer can also

add their needed items to their cart and buy those later on. An administrator will monitor the

website activities and manage the product items. The administrator also has the privilege ofdeleting a particular customer and to manage the cart and the bank transactions database.

Requirements Analysis &Specifications

Requirements Analysis

Following is a list of functionalities of the system. The system must consist of two

modules, Customer module or User module and an Administrator module.

Customer Module:

Visitors must create their account first to access the website contents.

After registration a visitor becomes a customer. Each customer will have unique user id and a password with which they can log in.

After log in the customer will be redirected to their own user-home page, where they

can select their preferred product and add it to the cart.

After adding to the cart, customers can also log out from the system and pay for those

items later.

The details specifications & price of each product must be provided at the website.

The customers should be able to update or delete their account if they want to.

Account must be prevented from unauthorized access.

The payment method will be online payment through credit card.

Administrator Module:

An administrator can log in using his user id and password like any other users.

After log in the administrator will be redirected to admin-home page.

The administrator can add, update or remove products as and when required.

The administrator can increase the number of stock of a product when required.

The administrator can manage the user database.

The administrator also has the privilege of managing the cart and the bank

transactions database.

Administrator can change the log in password if needed.

Conclusions

We have tried our best to make this system bugs free as much as

possible. We have designed it keeping in mind that our application looks like a

real time application. It is designed in a very user friendly way. GUI is designed

as simple as possible. System is made such a way that optimal execution timeis needed to perform an operation. Maximum level of security is implemented in

the application. Moderating privilege is given to the administrator as much as

possible.

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.

Still there are certain limitations in our web application and we hope tosolve that as soon as possible.
