Dear all,

I agree with everything said above, the point I wanted to make is just that we should probably not look to closely to what is provided by a DBMS or anything else but more to what we *really* need to satisfy our requirements. If soemthing is missing in one or more of the underlying systems we have to find a workaround. Please note that I highlighted the word *really*!
