title: How to map data with VS2012 SSDT project
body: <p>I am trying to investigate how to work with SSDT properly. Currently I made publish working however I can not understand how to use this tool for development.
  What I mean is that I can change the code, but how to see the actual result? I can add database to Object explorer and execute the statement, but how can I save it to the project after I made some changes?</p>
