I was just wondering what languages are most apt for building a group of web applications that will manage huge amounts of data, represent them in graphical form, and through repetetive learning, state trends or detect negative trends and suggest measures against such negative trends?
In simple words, where should I start in the development of an environment where data can merge with machine learning and website's with an aesthetic interface? How many people will such a project require and in what areas will these people have to specialize in?
