We choose Joomla when it comes to building custom feature-rich web solutions, taking advantage of its mature libraries and using external packages for time-critical tasks where circumstances so require.
Joomla extensions extend the functionality of Joomla websites. Five types of extensions may be distinguished: components, modules, plugins, templates, and languages. Each of these extensions handles a specific function. Components, plugins, templetes are few.
Like many other web applications, Joomla may be run on a LAMP stack. Many web hosts have control panels for automatic installation of Joomla. On Windows, Joomla can be installed using the Microsoft Web Platform Installer, which automatically detects and installs dependencies, such as PHP or MySQL. Many web sites provide information on installing and maintaining Joomla sites.
Joomla! utilises a configuration file (configuration.php, usually located in the root of the Joomla! installation) to control various settings including (but not limited to) database connection settings. Due to the use of a configuration file, migrating from one server to another is relatively simple.
