You must have successfully identified business keys before.
So it must be easy for you to show couple of examples (from your experience) where natural keys were just right to identify...

In most cases there isn't one.
I really have trouble understanding why you would say that.
Ok, I'll change it to "in many cases." My point was that it seems to...

That was exactly what I was asking about - can you show those cases when a natural key is the best choice?
I've worked in companies with a reliable employee number...

What is you natural key for "person" records?
In most cases there isn't one. I would certainly never use an SSN for this. But that doesn't mean that this...

Here in the U.S. we have been through a period of harsh language
We have? Must have been asleep....;-)

Heh.... I would tend towards the opposite, an OLTP is much more likely to be a candidate for an identity or some kind of system generated id because an OLTP...

And if you're one of those folks that think you can identify customers or accounts by some form of natural key because "IDENTITY" columns are supposedly evil, then you need...

I have also been accused of over-normalizing. In my view, however, those saying that simply weren't apply the rigor necessary to produce a correct database. And I know...

Perhaps one way to make restores easier is to generate the restore script at backup time for any particular full backup.
That could be a great way to improve the restore...

Not sure I agree with the complexity. I had a large database that took both a long time to backup and a long time to restore. Then, based...

Word of caution, a single instance of a dimension table used many times in a model will most likely result in an empty result set.
Not sure if I'm understanding...

For the frozen values: I need to historized or version the rows in the fact table using valid from and to columns, because business wants to know the value of...

That you know it's an accumulated snapshot table shows you have some grasp of this. I'm assuming that this is correct, though from your description, it sounds correct. ...

Thanks. A blank would be good enough. I know you weren't trying to tie a bow on the "Nope" answer, but a better way in this case would...
