What is a database?

A place on a web server usually used to store multiple items of data such as diary dates, blog entries etc. The data is stored in Tables with the Columns representing the different types of data and the Rows used for each new entry of data.

It is a very efficient way of storing data that is reused throughout the site as instead of creating Static HTML pages with the data in it a single page of PHP code can be used to display just the data required.

This can cut down on development time and allows for alterations to be easily made by the user via a CMS.
