Through XML configuration files, we are able to add several options without creating separate tables to hold the values. Parameters can be added to modules, plug-ins, and components with minimally-invasive code. Because modules and plug-ins do not allow for custom backend interfaces written in PHP, parameters provide an essential alternative for administrative control.

Components benefit from both view and global parameters. View parameters make it possible to offer different layouts with specific options. Global parameters are easily added to the component backend; they allow administrators to set options that apply to the component regardless of the view displayed.

The parameters for modules, plug-ins, and components match the style used throughout the Joomla! backend. It is a good idea to use them whenever feasible; they will be familiar to Joomla! site administrators who are comfortable with other extensions.
