Jacek,
I will look it up later (I am on a telecon), but my memory is that the
alert rate is about 100,000 per night, not 10!
An alert should apply only to a single object.

Maria,
Can an alert correspond to more than one object?
Probably not. Then you don't need a new table only and objectID in
the Alert table
That would work if the answer is 'no', especially given
that the Alert table will be compact. (Can someone remind
me how many alerts we expect per night? Assuming 10,
the Alert table will be growing 3,000 rows/year,
that is nothing.)
We should then keep the bit in the Object table
indicating whether there was an alert for given Object
(as Tim suggested)
thanks,
Jacek
