View as plain text  
from a purely religous logical architecture viewpoint it is better to
keep the business rules as close to the persistence layer (ex. RDBMS)
as possible.  in the practical physical/business world it is severly
hyperlinearly expensive (both hardware as well as Oracle licenses) to
support that model.

put another way:  Oracle is an insanely expensive application server
but my wife's in sales there so as long as people keep writing those
seven figure checks I'm not going to complain too much...  :-)

personally, I've been very impressed w/MySQL so far.  we use it to run
several sections of our site that run tens of millions of queries per
day.  MySQL replication has also been orders of magnitude more stable
than AQ ever was.  we have been replicating about 16GB/day across 12
nodes for months without the slightest hiccup.

just don't ask me to do SQL/Server!  when an RDBMS is responsible for
the biggest DOS in the history of the internet that should tell you
something...  there, if we're going to flame let's at least pick a
target we cal all agree on...  :)
