title: Tool for creating relational model diagrams
body: <p>I'm looking for a free and simple tool for creating relational model diagrams.</p>
  
  <p>All that i need is to be able to draw tables and fields and connect fields that are foreign keys to their referenced tables. </p>
  
  <p>As an example I found this <a href="http://www.eng.mu.edu/corlissg/150.07F/12assets/examMid06/RG_Fig2_8_relational_model.jpg" rel="noreferrer">image</a> on the net.</p>
  
  <p>I don't need anything more: I want to keep schema simple and clean.</p>

  <p>Thanks for your answers. However, a friend of mine suggested that I can use any vector graphics program. His advice helped me to found the beautiful "LatexDraw" editor.
  It's worth a check, especially if you care about printed quality.</p>
