title: Why would you use Oracle database?
body: <p>I'm curious for technical reasons why you choose Oracle database versus the latest flavors of:<br>
  1) Microsoft SQL Server<br>
  2) MySQL<br>
  3) PostgreSQL  </p>
  
  <p>What features or functionality justify the extra cost.
  I'm interested in technical arguments, not a religious war. 
  A friend asked me this and I've always used one of the 3 I listed.
  I didn't know enough about Oracle Databases to offer an opinion.</p>
  
  <p>Thanks.</p>
