title: how much data can a 5MB SQL database store?
body: <p>I'm interested in using Heroku for my project. I'm not interested in paying for it at the moment but the free plan only offers a 5MB database.</p>
  
  <p>Is there any measure I can use to know how many columns/rows of simple text data can be stored in a 5MB database?</p>
  
  <p>Thanks</p>
