But it was long ago, and maybe needs to be redone?
Edit: after re-reading it he treats it as a distributed system because client and server is over network. And that is true, it can also be thought of as a distributed system because as you said transactions are concurrent and are running as separate processes. Although in these cases you can't have a partition (which aphyr uses to find weaknesses), or maybe there is something equivalent that happens?
