What is a CMS?
The abbreviation CMS is short for Content Management System and the name conveys what is at the heart of these tools - they are systems which web authors can use to manage the content of a web site or web application. Many of the forerunners of today’s CMS were created as simple off-the-shelf packages which allowed users to run their own blogs and the concepts are still inextricably linked. However, from humble beginnings most have evolved to offer much more than that, to the extent that they are now heavily used by the even the most experienced web developers as the building blocks of advanced websites, utilising extensive support communities and wide ranging plugins and modules. They can therefore provide the uninitiated with an easy route into online publishing within minutes but also provide advanced users with valuable efficiencies and reliability in contrast with coding websites from the ground up.
The three most widely deployed content management systems on the world web today all use PHP (PHP Hypertext Processor) as the server side scripting language (the code that is run on a server and determines what data is delivered when a web page is requested). The first part of this article looks at these three CMSs.
WordPress
This CMS is recognised as the most used CMS on the web with estimates that it comfortably accounts for over a half of all CMS builds - almost two thirds in some surveys. The CMS began life as a blogging platform and is still, in its basic form, orientated towards this function, however a broad array of plug-ins and themes means that it also has the potential to be used for more complex web sites. Therefore, WordPress has become massively popular with personal bloggers and corporate web developers alike.

Drupal
Created originally as a forum platform, Drupal has become very popular due to its flexibility and is now used to build a wide array of website applications. The ‘out of the box’ Drupal build is known as the core and allows the user to add content to build a simple website, blog or forum, but the site is supported by an extensive community and it is the add-on modules that they create which gives Drupal its potential. Drupal is therefore commonly referred to as a content management framework due to its reliance on add-ons for functionality.
