None of the other VMS databases (O, I, or S) come close to offering
"blob" support like Rdb. For images and graphics, call the
ADDS/multimedia folks in Atlanta .... you'll be glad you did. Talk
to Cyndi Peddigree. If gridded access = 2 or 3 dimensional arrays,
the consultant may be right because, in general, the relational
model does not support the concept of repeating groups (ie arrays).
However, I'm sure there are many applications with deviate from this
for performance or other reasons.
>> - Rdb performance is poor for handling bitstream/binary data
I guess this consultant has run his own benchmarks and can show
the numbers of his Rdb work ? (Don't you just hate this when a
guy shoots his mouth off without having personal experience !!)
>> I don't have experience about this, so I am not sure about the consultant's
>> comments. Could anyone comment about Rdb's capability in this field?
Make the consultant show his numbers (and earn his $) and offer to work
with "Mr. Smarty" to prove him wrong. Rdb should do just fine ...
thank you very much ... providing appropriate transaction design and
physical design.
>> Do we have benchmark result for this?
Make up your own benchmark since the weather broadcasting metrics have
not yet been finalized by TPC-A.

| Haven't seen anything to touch EMPRESS's ability in imaging.
The product supports 16-dimentional arrays and NOAA and Smithsonian
have done some lovely things with it. Because the product's so
specialized, start-up time to write an imaging application could
be less than 2 weeks. But this Toronto-based company's very small,
so support issues might be a problem.
