FIGURE  28.4    The user    logs    in  to  the database    server  located on  host    Simba
from    the workstation (host   Cheetah).   The database    client  is  running on
Simba.
In  the other   scenario,   shown   in  Figure  28.5,   the user    logs    in  to  a   remote  host
through SSH and starts  a   program on  it  to  access  the database,   but the
database    is  actually    running on  a   different   system. Three   systems are now
involved:   the user’s  workstation,    the remote  host    running the database    client,
and the remote  host    running the database    server.
The important   thing   to  note    in  Figure  28.5    is  the middle  system  Leopard.
Although    the client  is  no  longer  running on  the database    server  itself, it  isn’t
running on  the user’s  local   workstation,    either.
