Just do history table as copy of main one, with additional columns who and
when changed.
Then create trigger to fill history table when any delete/update occurs.
Fill history table with :new data.
Making one row from all column maybe dificult when length of data exeed 8000
(max for varchar2)
unless you use a BLOB's, but it's sounds horrible to me.
