Shakthydoss - What is the difference between Artificial Intelligence, Machine Learning, Statistics, and Data Mining

Few day ago before I saw an interesting question on stats.stackexchange.com After spending few minutes of readings and analyzing all answers on stack I felt writing my thoughts assuming what I would have answered if I really had too. What is the difference between Artificial Intelligence, Machine Learning, Statistics, and Data Mining? Would it be accurate to say that they are 4 fields attempting to solve very similar problems but with different approaches? What exactly do they have in common and where do they differ?
