title: Difference between PowerShell / SQL Server snap in's / tools?
body: <p>I'm a bit confused with PowerShell snap in's and other "tools" that interact with SQL Server. So what is the difference between these tools:</p>
  
  <ul>
  <li>SMO </li>
  <li>SQLPS Module </li>
  <li>SQLPSX</li>
  <li>SQL Server PowerShell provider</li>
  </ul>
