title: When should i upload a file into a database instead of the server in a web application?
body: <p>As the title says, i am concerned about when i should upload a file on a database rather than the server.</p>
  
  <p>In these days i first encountered the necessity of uploading .pdf files into my web application in order to make it accessible for everyone who needs it.
  But my first approach at it was uploading a file into a database.</p>
  
  <p>But that wasn't my case; i just needed to upload a file and, with a download link, make it downloadable from the user.</p>
  
  <p>But on the other side, i wondered, since the big limitations of "blob" type: when should i upload a file into a database rather then the server?</p>
