title: Should I use multiple databases?
body: <p>I am about to create an application with Ruby on Rails and I would like to use multiple databases, basically is an accounting app that will have multiple companies for each user. I would like to <strong>create a database for each company</strong></p>
  
  <p>I found this post <a href="http://programmerassist.com/article/302" rel="nofollow noreferrer">http://programmerassist.com/article/302</a>
  But I would like to read more thoughts about this issue.
  I have to decide between MySQL and PosgreSQL, which database might fit better my problem.</p>
