Le text mining et le web mining en est une illustration parfaite : il faut d'une part maîtriser les outils informatiques qui permettent d'appréhender les données sous des formats divers (on parle de données non-structurées) ; et, d'autre part, bien connaître les techniques de machine learning qui permettent de mettre en évidence des régularités sous-jacentes aux corpus de documents. While I think it is able to fulfill most basic needs, there is of course a limit on how much you can customize as compared to coding. Happy coding!
