I'm sure this in the documentation somewhere so I apologize ahead of
time
for what may be a dull posting, but can someone explain the different
parts
of an entry in the tnsnames.ora file?  I understand SID, Protocol, Host,
and Port,
but I'm confused by ".world", what the difference is between that and
"Community",
as well as address_list and address.  Any comments would be
appreciated.  If someone
knows where in the documentation to look for a detailed explanation that
would be nice as well.  Oracle 7.3.3 or Oracle 8 documentation.

Example1.world =
  (DESCRIPTION =
    (ADDRESS_LIST =
        (ADDRESS =
          (COMMUNITY = tcp.world)
          (PROTOCOL = TCP)
          (Host = Production1)
          (Port = 1521)
        )
    )
    (CONNECT_DATA = (SID = SID1)
    )
  )
