title: SQL Server 2008 vs SQL Server 2008 Express size
body: <p>I migrated a SQL Server database (source) into a SQL Server Express database (destiny). Used "generate scripts..." in SSMS. </p>
  
  <p>I verified if the tables (tested with the 3 biggest tables) in the source DB had the same number of rows has the Express and all looked OK.</p>
  
  <p>I executed <code>sp_spaceused</code> and found that the original database size is 16MB, while the Express version is 4MB. </p>
  
  <p>Does the Express DB uses less space or is this a sign that something went wrong with the migration?</p>
  
  <p>Thank you</p>
