A person who have seen an E-Commerce site might have noticed a few key things like a CATALOG,a SHOPPING CART, a PRICE CALCULATOR, PAYEMENT MECHANISMS etc.The author would like to briefly explain on a few terminologies related to an e-commerce site.A CATALOG is analogous to a menu in a hotel, or simply it helps the customer to reach to his/her product immediately.A SHOPPING CARTin the e-commerce site in real world is a shopping basket at a supermarket,where the customer can put his/her product of choice and it is this cart that goes to the billing sesion.A simple difference from the realworld is that this cart can be saved for further purchase,may be some other time.A customer can even cancel the CART and add new item in his later logins.
The visitor Experience in an E-Commerce site is shown in the picture.

CHECKOUT: This process will initiate the ordering of the products in the shopping cart.So it will move the focus to shipping info, billing info, payment details etc.One other important thing when considering the completion of an order is PROMOTIONS, which are a way of advertising from a Business perspective and a discount from a consumer perspective.GIFT COUPONS also come iunder the same category but the way they works is slightly different.

Now there is one part which a consumer never see but he/she feels it.That part is called the “fullfillment” which is simply the delivering of the product on time.Eventhough author is mentioning it as simple as that , it is the key factor in the success of the e-commerce site, CUSTOMER SATISFACTION.Hope the article gave an overview on an e-commerce site.Now these cycle of components ca’t be created easily and that is how the concept of a framework for commerce application came.And one such framework is ATG framework which helps the developer in his chores.

ATG is a HOT technology.It helps us build effective marketing and sales solutions.Building an E-commerce application is made easy through ATG commerce framework.ATG is the acronym of ART TECHNOLOGY GROUP and the framework is developed by this group and hence named the same.It got introduced to market in 2007 and the latest versions are ATG9.0 and ATG9.1
