Web Enabled Databases

By using a database driven website, you can update, query and publish information in a variety of ways.

When someone clicks on a web page whose content depends on the database, the web server determines which elements are needed and then requests those elements from the database. The required information is then passed from the
database to the web server: thus, the database becomes a ‘web-enabled database’.

For example, the Amazon website www.amazon.co.uk uses a web-enabled database. If you visit the site, your searches and selections will be executed by the Amazon database and the information you see will have been obtained from that database. The content of the Amazon web pages is dynamic:
if the database is updated, the information seen on the corresponding web pages will immediately reflect the updates.

Any website or web application that is data-driven will work in this way. The application in the web browser is simply the front end interface to a database back end hosted on a remote server.
