Say you have an Order Header/Order Detail relationship. You're writing
an application that deletes the Order Header record.  How does your shop
handle referential integrity?

1.  We do it programmatically-- our application looks in the Order
Detail 
     file and makes sure there are no corresponding Order Detail
records.
2.  Our shop standards require we create constraints through DB2/400.
3.  We don't bother checking.  We just delete the Order Header record. 

Thanks
