Every day, we create 2.5 quintillion bytes of data. This data comes from everywhere: sensors used to gather climate information, posts to social media sites, digital pictures and videos, purchase transaction records, cell phone GPS signals, and Spotify music downloads. Put it is this way, anything you do over the web is being tracked. With over 7 billion people in the world, the amount of data we create on a daily basis is mind-blowing. Below we created one chart that really put BIG DATA into perspective. 90% of the data in the world today has been created in the last two years alone.
