title: Branches and trunk in SVN
body: <p>I am an SAP developer and in the SAP landscape, we have a Development server (DEV), a Quality(QAS) server (for testing) and the Production(PROD) server. 
  Developers develop their programs in DEV and then transport it to QAS. In QAS, testers test the program and then transport it to PROD. Later it is deployed to the client from PROD.</p>
  
  <p>I am new to using SVN and was wondering if and how the SAP landscape is analogous to the trunk/ branches/ tags(?). </p>
