Drupal: text...stored in a database

End user guide | drupal.org: "Most of the content on a Drupal-based site - the text of this page, for example - is stored in a database. Text and images are submitted by filling in forms via a web-browser. When visitors view a page, Drupal gets the relevant bits of content from the database and composes all of the components of the page in a template. This makes it easy to quickly add or change content, without requiring knowledge of HTML or other web-technologies on the part of the person providing the content."
