title: Do I need a database for my nodejs application?
body: <p>I need to create a heatmap that displays density regions corresponding to Ipv6 addresses in the world. I can populate this heatmap (densities) by parsing a csv file and filtering for Ipv6 addresses and the associated lat,long coordinates. </p>
  
  <p>Do I need a database to store this filtered information? Or can I write my application (the client side) in such a way that every time I go to the index.html page, the client side processes this csv file and populates the heat map? Also, there's a caveat that the csv file can be changed. Wouldn't that mean if I were using a db, I would need to repopulate the db with new data from the new csv file?</p>
