Data Driven Website Design
These are websites that have some or all of their content controlled by a database; this technology is used by CMS (Content Management Systems), some e-commerce sites and sites that offer membership services.
The advantage of the a data driven website is two fold it allows each up date to content, it allows visitors to have personalised content and services, the same content can be used on several different web pages with out actually duplicating the content and also the pages are only created when viewed so information can change between viewings.
If you want to offer special services to a your members a data driven website could be helpful, it can hold information about your members preferences, things that like to be kept informed about and even to associate them with groups on your network.
For e-commerce sites a data driven site is also invaluable, customers can easily search your entire product range, you can easily add new products and suggest related items or items that other customers have purchased recently.
