For delete you can use a constraint defined with cascade delete.

For the rest
create or replace trigger redun after insert or update on foo for each row is
begin
if inserting then
 insert into <other table>
values (:new.<column1>,:new.column2,... etc) end if;
if updating then
  update <other table>
 set non_key column1 = :new.nonkey column 1

    , non_key column2 = :new.nonkey.column 2 where key_column = :new.key_column;
end;

Could you please refrain from posting to *all* oracle newsgroups, at least one of which is not distributed by my provider. There is really no need to do that. Questions like this one belong in the .server newsgroup.
