The Facebook Graph API allows us to interact with the facebook platform directly. We can use it both for getting and for adding data. Learning how to use it is much simpler than learning how to use FQL (Facebook Query Language).
The Facebook Social Plugins allow us to integrate the facebook platform into our web site by copying simple HTML/XFBML code snippets into our HTML code. Web masters can easily integrate the facebook platform into their web site.
You can watch few samples for the topics covered in these courses watching the video clips listed in my Facebook Youtube Playlist.
