Content Management Systems are database driven web site applications where the structure of the site is separate from the content. This allows the user to add and remove their own content via any web browser.
I use OpenSource applications mainly Joomla!
The latest Joomla! build can be installed on my hosting free of charge.
The fantastic thing about OpenSource software is that it’s free to use in most cases.
Joomla! sites require access to a MySQL database and this is supplied with all Joomla! installations.
