I'm not quite sure I understand why you believe that the
middleware approach will be such a performance bottleneck.

I'm going to take a guess that it has to do with the
cost of passing data between the middleware process and the
server process...Am I correct?

If that's the case, then I believe that your performance
concerns are unfounded...

The architecture of the Oracle server depends heavily on a
large chunk of shared memory known as the 'System Global Area'
(aka SGA) for storing and working on data from the database
files. The middleware process could potentially work directly
against the SGA...instead of having to serialize and send data
between itself and the server; thus realizing a significant
savings in time.

I don't know for sure if this is how Oracle has architected their
data cartridges; but if *I* were on the architecture team, that's
certainly how I would do it... :-)

Well, testing and certification of datablades is certainly a
step in the right direction; but as almost anyone in the software
industry will tell you, testing software doesn't guarantee that
it will be bug free...it merely reduces the number of bugs in
the resulting product.

Likewise, the Oracle solution isn't perfect either...there is
still some room for data corruption. So in essense, there is
no perfect solution here; simply shades of gray. The Informix
solution *might* be a teeny tiny bit faster, but the Oracle
solution is less prone to data corruption...

Of course all of this is educated guessing on my part. We won't
know for sure until the products are released. :-)
