Abstract The business-to-consumer aspect of online shopping is the most visible business use of the World Wide Web. The primary goal of an online shopping site is to sell goods and services online. This project deals with developing an e- commerce website for online shopping. It provides the user with a catalog of different goods and services available for purchase in the store. In order to facilitate an 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 (MIIS) and PHP, and a web browser as the front end client. In order to develop an e-commerce website for online shopping, 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 C#, VB.NET), relational databases (such as MySQL, Access). 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 for online shopping.
