  comment = {Better to cite dewitt:gamma3. Multiprocessor (VAX) DBMS on a token
  ring with disk at each processor. They thought this was better than
  separating disks from processors by network since then network must handle
  {\em all} I/O rather than just what needs to move. Conjecture that shared
  memory might be best interconnection network. Relations are horizontally
  partitioned in some way, and each processor reads its own set and operates on
  them there.}
