title: What are the differences between these IBM.Data.DB2 dlls?
body: <p>I have these dlls installed on my box. What are the differnces between them and when would I use each?</p>
  
  <pre><code>IBM.Data.DB2.dll
  IBM.Data.DB2.Entity.dll
  IBM.Data.DB2.ASP.dll
  IBM.Data.DB2.9.5.5.dll
  </code></pre>
  
  <p>One other thing, my db2 data is on Z/OS Mainframe, if that makes a difference.</p>
