But you can compress the tablespace & put all historical data in it, this
doesn't mean we never back & look at the historical data.
Correct me if I am wrong?

Well, let me put it this way: if it is accessible, then you are
doing something wrong. Try with the Ultimate Compressor (TM)
instead. It's called "rm". That will make sure that your data
is no longer accessible. As for the compressed tables, they have some
problems: you can no longer add/drop/modify column, creation of indexes
takes longer and I got ora-600 when I was looking for chained rows.
