Stéphane Faroult first discovered relational databases and the SQL language back in 1983. He joined Oracle France in its early days (after a short spell with IBM and a bout of teaching at the University of Ottawa) and soon developed an interest in performance and tuning topics. After leaving Oracle in 1988, he briefly tried to reform and did a bit of operational research, but after one year he succumbed again to relational databases. Stéphane has been continuously performing database consultancy since then, relentlessly improving queries and trying to teach good SQL manners to developers. He is the author of The Art of SQL and of Refactoring SQL Applications.
