title: Visio database diagrams, associating columns
body: <p>I'm trying to be a good developer and create some documentation before I start programming my next project.</p>
  
  <p>I have created a database schema diagram in Visio and created relationships between columns.</p>
  
  <p>However, I am looking for a way to make the relationships between columns more clear.  I want the arrow to connect column to column.</p>
  
  <p>Is there a way to do this in Visio?</p>
