Here is a case. Using SQL, dig through the call centre data and find out who called before the fire started.

Use SQL to explore the data, filter it, connect the pieces. The easy levels teach you the basics and the hard ones put you in the shoes of a real data forensic, meaning an investigator who works on data.

Using the whiteboard system, you can build charts and leads, and make sense of every piece of the case in order to solve it.

Two case campaigns are available right now: find out who set the school on fire by searching the call centre databases, and track down a criminal by watching how people move through the Paris metro.
