Joomla! employs a specific naming convention, which is used by all components. Each component in the system has a unique name with no spaces. The code is split into two folders, each bearing the component name prefixed by com_. The component in this book will be called restaurants. Therefore, you will have to create two folders named com_restaurants:

When the component is loaded from the frontend, Joomla! will look for a file with the component's unique name ending in a .php extension. Within the components/com_restaurants folder, create a restaurants.php file. Similarly, running it in the backend also assumes the presence of a file with the component name followed by .php. Add the restaurants.php file in administrator/components/ com_restaurants folder. Leave both of the files empty for the moment.
