Jack,
AFAIK, SQL still won't allow you to insert bad data (remember, checking is
done at write/update time).
There is a nice paper about Data Modernization by Dan Cruikshank here:
//www-03.ibm.com/systems/resources/systems_i_software_db2_pdf
_Performance_DDS_SQL.pdf
Check it out, it is quite interesting
