E-commerce (electronic commerce) is the buying and selling of goods and services on the Internet.
An E-Commerce web site is broken down into 3 main areas:
The first is the catalogue of products or services, this is where users of the site browse for products they may wish to purchase.
Secondly is the secure payment area, this can be performed on your web site via secure hosting but for smaller businesses is usually sent (via the internet) to a third party payment provider.
Finally is a password protected administration section where the site owner can manage all products and orders placed on the e-commerce website
