I heard that the main difference between latch and flip flops is that latches are asynchronous while flip flops are edge triggered which makes sense. But when I check out their shematic they seem pretty much same. Here is the design of a dlatch from one book which I can understand

But here is the D Flip Flop shematic I found in various tutorials

They pretty much look same to me,where is the difference?
