These meetings are an extraordinary occasion to those of you interested about MongoDB. In only one session you can learn from experts and meet people like you.
We could attend the talk of Roberto Ansuini from Fintonic, other by Nuxeo guys and the last one by the MongoDB Director of Solutions Architecture for EMEA Arthur Viegers about IoT and time series data.
I tried to talk in a friendly way about Safety, I like everybody understand me. In order to achieve that goal I used these medieval characters: A King, his Kingdom, castles, goods, emissaries, etc. I think I got it. Here you have the slides: MongoDB Users&Roles.
