title: Is the column-family based data model of Cassandra the same as the column-family based data modle of Google's BigTable?
body: <p>Well if I understand correctly, Google's proprietary BigTable is built on Google's proprietary GFS.</p>
  
  <p>So at the homepage of <a href="http://cassandra.apache.org/" rel="nofollow">http://cassandra.apache.org/</a> they are actually claiming to have BigTable's column-family based data model?</p>
  
  <p>I mean i really do not see how it is possible.</p>
