title: What is a distributed database system?
body: <p>I comment
  I understand perfectly that it is a database but, I do not know what is referred to as "Distributed System".
  In this type of systems the information is centralized or in different nodes?
  If so, is the same information found on all nodes?
  Or, the information is fractioned in the different nodes? (ie each node has a part of the information).</p>
  
  <p>Thanks in advance</p>
