Well no, someone has to worry about this.  I guess when I said RDBM*S* I 
meant RDBMS *team*.

Sort of.

I just don't see the data point of "does the data fit into memory or not" as 
being relavant to the discussion.  If you have relational type data and you 
want to run various reports that look at the data in various different ways 
for reports, what does "have it in memory" have to do with anything?  
Whether it fits or not, you still have to hand write code that does 
relational joins and other things to deal with it.

My last (relevant) project would have easily fit in memory, but downloading 
MySQL, building 3 tables and loading up the data was *vastly* faster then 
hand writing all that stuff for about 10 reports that had to be run one 
time.
