title: no pycharm database window
body: <p>I'm following a tutorial on Django.  I'm using PyCharm 2016.2.1.  There is a file in my project called db.sqlite3.  The icon next to this file in the project explorer shows a question mark which indicates PyCharm does not know what this file is.  In searching the web I find many references to clicking View > Tool Windows > Database.  In my setup there is no Database option under View > Tool Windows.</p>
  
  <p>Sqlite3 is supposed to be native to Python/PyCharm yet I don't seem to even have a Database option.  What am I doing wrong?</p>
