Online Web Application For Selling Computer Products Computer Science Essay

This project report represents the idea of the Online Shopping Website application for Computer products. In this project we are having primary goal of to increase the sale of the Computer product in the market, and to reduce the manual work and increasing the technical support for sellers and buyers to sale or buy product online. The second goal of this site is to maintain the data of buyers, sellers and product.

1.2 PROBLEM STATEMENT:

In the current system all transaction are doing in manual that is very time consuming and it is very difficult for maintenance. They have to maintain all data in books and register that is very difficult to finding any data in those lots of registers and books so it is very time consuming and wasting of money. So to overcoming all these problems we can use Online Shopping for Computer product. The online shopping is the part of internet to do online purchasing and selling product with electronic security, now day this is called as E-commerce. Customer can directly purchase the product online from his/her home through internet. Customer can see many products and details about the products which are not possible in current system. Customer can pay online through credit card there is no need to keep big cash in pocket and physically going to the shop.

1.3 PROJECT AIM AND OBJECTIVES:

The major of website for Online Shopping is sale and purchase computer products and services through the internet. This transaction does with the electronic data exchange over the internet. Customer has to give credit card details for purchase product with secure transmission of data exchange over the internet.

The Online Shopping website has many objectives some of them as follow:

It gives information about various products of different categories.

Customers purchase the products online with the help of internet.

Customer will login on website for shopping.

Customers purchase the product with checking the price of product and can compare the same product with different categories product.

Customer will pay online payment so security is more important so for that the secure transmission layer is used.

After purchasing product customer can have any problem with product so he can give the details about the problem and get solution for that as per require time.

Data security is more important because customers personal details are stored in the database so the database is access by only authorize person or admin.

I strongly conclude that implementing this type of application is very useful for online users and sellers of product or owner of the site.

1.4 PROPOSED METHODOLOGIES:

In this project we follow the Software Development Life Cycle (SDLC) methodologies use to develop website. I have used Waterfall Model to develop this website. The main steps in this methodology are Requirement, Analysis, Design, Implementation, Testing and Maintenance. The waterfall model is also called as linear sequential model, in this model all tasks are completed one by one. To use this model the major advantage is very simple and all project development process takes place as per the user requirement.

This system will provide easy maintenance for future references.

2. RESEARCH:

2.1 GENERAL BACKGROUND TO THE SUBJECT:

Java technology is the most popular and robust technique to develop any kind of projects such as window application, web application etc. J2EE is the java enterprise edition to the develop web application. To developing this website I have used JSP (java server page), Servlet and Java beans which are part of J2EE technology. These technologies basically used to give request and take response on server side.

Model view controller (MVC) architecture:

Figure: MVC architecture

Model:

The model is related with classes which represent the application data, this model responsible for know what the data is, how to create, delete, retrieve and store the data.

View:

It is basically used to show the data and notices in user interface which user wants to change it.

Controller:

These classes basically provide logic of the application, which is responsible for coordination the data in the model and the view.

About the data base:

The MySQL is one of the popular database for developing server side application or web application, it has more reliability, performance and simple to use. The MySQL database is open source, so it’s saving time and money and it can run on most platforms. It is specifically use to store large amount of data or records, So Online Shopping website use MySQL database to maintaining the data about the products, customers, sales, purchase etc.
