The World Cup is here. Portugal may be going through a big financial crisis (just like in the last 10 years, we're actually used to it) but for the next month all of that will be forgotten: It's soccer time!
I may not influence how my team plays in field, but fortunately Mozilla started Firefox Cup, where I can, indeed, be a player in the field.
What does this have to do with BI?
Well, actually, a lot! It's a well known fact - mainly because I keep repeating it proudly :) ) that we are part of the mozilla metrics team. And turns out that my alter-ego, email@example.com, is in some sense the referee of this tournament!
This is a screenshot of the current score of the tournament. And where do those numbers come from? From the analysis of the logs generated by (much) more than one hundred million firefox users daily. This translates into the analysis of a few gigabytes of logs that are generated every hour. Through a somewhat complex and fine-tuned etl process, we are able to get all relevant data into a datawarehouse and, not more than 4 hours after midnight, be able to provide the accurate usage number for each of the existing 150k personas. Here's the current Portugal persona chart:
This numbers are then integrated into the Firefox Addons databases and are available for the world to see. In case you're noticing the discrepancy between the values in both of the charts, it's easily explainable - the number of users on the addons page is the 7 day rolling average, to prevent the "weekend effect', making the curve much smoother than just printing "yesterday's number"
And it's absolutely amazing the amount of cool analysis that we can do on this subject, and we hope to be helping the personas' team driving their strategy!
