title: How could I modify this database design to store user history?
body: <p>I have the two tables as pictured below. These are being used to track users current location when they make check-ins at various locations. I'm wondering how I might be able to modify this so I can store users history as well. I want to store all the past locations that a user has checked-in at as well as their check-in and out times.</p>
  
  <p>This could either be adding new columns to the existing tables or some additional tables.</p>
  
  <p>Thank you!</p>
