Adding to the answer above, to check if the same records
are present in both the datasets we have to specify keys.
If the same keys are present in both the files, then it
is 'Copy'/'Edit', if the keys are present in before but not
after then it is a 'delete', if the keys are there in after
but not in new then it is an 'insert'.
To decide if the record is a copy or edit you have to
specify change key. If the main keys match and teh change
key also matches, then it is a 'copy'. If not, then it is
a 'edit'.
