title: Why should I insert blobs in database instead of filesystem?
body: <p>I have to manage some files in a web application, let's say the avatar images of user profiles. 
  I asked myself: should I use a blob field in user's database table or simply in a filesystem file like <em>avatars/{userid}.jpg</em>? What are advantages to store blob into database if I do not need search capabilities in this field?</p>
