The new fact (or not so) in computer science field is data. Indeed, today we hear advent of some new expressions like “data thinking” that proves the wish to debate on this one. We all know Business intelligence that has almost 60 years since Hans Peter Luhn, a german computer scientist, has defined it. But nowadays, we notice some jobs that get their flight on problematics that can’t be handled by BI’s resolutions, in addition to the digital transaction.
