title: It's better to keep one week or one day in a row of an table in SQL?
body: <p>I'm doing a system that keep presences about the users, your know, if they are in that day or not.</p>
  
  <p>I simple want to know if it would be more practical to keep data about a entire week in a table's row or only a day per row.</p>
  
  <p>If it's a week per row it would have this attributes:</p>
  
  <p>user : varChar<br>
  day 1 (Sunday) : dateTime 
  day 2 (Monday) : dateTime 
  ...<br>
  day 7 (Saturday) : dateTime  </p>
  
  <p>If it's per day:</p>
  
  <p>user : varChar<br>
  date : dateTime<br>
  presence : boolean</p>
  
  <p>So? What do you think?</p>
