title: Where does Facebook store multi millions of Images and Videos. In database or somewhere else? if so, Where?
body: <p>I am completely new to database. I require some information regarding where does the Facebook which stores millions and millions of pictures and videos. Do they store it in their database and then the images/videos gets retrieved through the query? I have read few times from some people that you should not store the images/videos in the database but they never mentioned why and where else should you store them if not in the database. Please provide me as much information as possibly you can. It'll be highly appreciated. </p>
