The idea of 'integrity' in sql is immature. Unfortunately most here are only
familiar with
what is served up as 'integrity' in bol. Imagine if sql was as 'dedicated'
to integrity as
it is to performance. What sort of 'integrity' features would it have? Could
you call
it more than 'decent'? Let sql do what it does best - access data. Using sql
to define
a schema is using it at what it does not do best. Such a simple concept -:)
