title: SQL Server mdf files not changing
body: <p>Here is a SQL Server question.</p>
  
  <p>While data is getting populated or deleted from a data base (ex. NorthwindDB), the corresponding mdf file is not changing at all. But to test this I restarted the SQL Server services and I could see the change in time stamp and size of the mdf file.</p>
  
  <p>Is there any way we can force the data base changes to reflect in the corresponding mdf and ldf files without restarting the SQL Service.</p>
