title: How do I tag a database component in UML?
body: <p>In an UML component diagram, how does one tag or identify a component as a database, so that it's easily recognizable? In the old days there was the cylinder symbol for showing database but that's not part of the UML. Same goes for an application server for instance, how would that be shown?</p>
  
  <p>Are stereotypes applicable here? Can the component symbol be enhanced with graphical elements?</p>
