Joomla is open source content management system which is written in PHP. Joomla enables you to build powerful applications and Website.

Joomla offers a wide variety of customizations and extensions. You can also access Joomla on just any platform including the Apple's iPhone. Being open source, it provides a wide platform.

How does Joomla allow users to manage content, add or delete articles on a site, and maintain the site via a web browser interface? Joomla separates the content of the site, all the text, images, videos, podcast, usernames and passwords, and whatever else you may have in your content bin from the actual presentation of that content. All content is kept in a database on your server. The information on how to display that information is kept in a template. When Joomla is called on to serve a page from a browser, it gets the content for that page from the database, looks at the template files to see how it should be laid out, builds the page accordingly and sends the page to the browser.
