Big Data, Small Dashboard - Andrea Maietta - Codemotion Milan 2016

Big data is the new black. We have more data than we could use, but what we really need is information. The typical dashboard is completely crammed with colourful 3D pies, uncountable lines and tons of extra-thick tables. And nobody understands anything. Knowledge is power. But to be able to know you first have to understand. In this talk we shall see how to transform a terribile mess into a clean and informative dashboard, moving step by step and explaining the reasonings between each passage. At my signal... unleash knowledge!

  • Nothing short of a miracle! I'm writing on behalf of my husband to send you a BIG THANK YOU!! The improvement has been amazing. Peter's sleep apnea was a huge worry for both of us, and it left us both feeling tired and drowsy every morning. What you've discovered here is nothing short of a miracle. God bless you. ●●● https://bit.ly/37PhtTN
