Never heard of event sourcing before, but I've used this pattern myself (as another comment mentioned, when you need it, it's a fairly obvious way to do it). Looking it up, I am guessing it's from Martin Fowler's book about patterns and architecture design? And on a related note, would you recommend the book to the average developer?
