title: MySQL vs DB2 RDBMS
body: <p>Is there s significant difference between the two? MySQL is used by YouTube, Google and Facebook while DB2 has the highest benchmark scores. Are there areas or cases where using a specific one would matter? Like size wise it is said that DB2 is really good on very small and very large databases (not sure why). </p>
  
  <p>Any feedback or suggestions?</p>
  
  <p>P.S. I'm more looking for functionality and capability differences.</p>
