Their new thesis is that specialized hardware is not necessary and has not been successful, but that parallel database systems are clearly succesful. In particular, they argue for shared-nothing layouts. They survey the state-of-the-art parallel DB systems. Earlier version in Computer Architecture News 12/90.} }
