The shopping cart system exists online as it has existed through brick-and-mortar retail shops and department stores. Whereas the shopping cart of the physical world provided a straightforward means of shopping by selecting your products, throwing them into the cart, and unloading them all before the check-out girl, the virtual shopping cart enables you to buy hordes of products with just a few simple clicks of the mouse button.

The shopping cart system is made up of a single or multiple software applications that enables the vendor to get his products displayed online and available for sale. On the customer side, the system assists the online purchaser in what he chooses to buy by storing the product information, the number of products purchased, all the related item information, and the financial information of the customer.

That system is made up of two parts, the storefront side and the administrative side. The storefront side is the Web page that actually displays the products and all the related information. This is where the customer sees the marketed product as it is, complete with images and customer reviews. The storefront may contain additional marketing material, and most definitely includes functions to make the sale happen, such as coupon codes and product quantity text boxes.

The administration component is where the vendor can edit the details of all his products posted. The information is kept in a database, and depending on the type of shopping software used, it can be stored in his server or on the site of a third party. This is the portion where the vendor can update or add products, create Web pages to go along with each product, and generally manage customer orders.

A complete commercial shopping basket system can be purchased like any regular product. The software can be stored in the vendors server, complete with an administrative site and database applications. This means all the product and customer information can be stored on one site, the vendors server, therefore increasing convenience and safety.

There are also online versions of the system, like a hosted service. There are particular third party service providers that host shopping carts software online. This can simply be accessed by the vendor through a Web browser, making the whole administrative activity fast, convenient, and time-saving. However, the downside to this is that your product data and sensitive information about the customer may not be safe and secure from hacks and malicious administrators. Additionally, the whole process is subject to the speed of the vendors Internet connection and provider capabilities.

Since all information, product-wise and customer-wise, is stored online, security considerations have become very important in creating and maintaining E-commerce systems like these. With the right tools, a hacker can charge the cost of a product to an existing customer account and acquire the item himself. Nowadays, shopping cart systems are made to ensure that the utmost and strongest security features are present and running when a customer hits that buy button.
