by
definition, their product is a combination of software/hardware. Their hardware
runs an NCR flavor of Unix, has specific disk farms, and has a specialized piece
of hardware/software for the BY-NET(their version of the interconnect). you
combine their nodes into cliques (4 nodes to a clique), and bolt multiple
Cliques together.. Their RDBMS is embedded with the hardware as well.. Usually
don't purchase just the software - it's a package (hardware and software)... The
hardware can run Windoze, but the ability to plug in the multiple nodes together
as a shared nothing infrastructure works best with their Unix OS on their wintel
hardware.
oh well
- it's friday, its cold, and there is a bunch of high school football on TV in
Georgia this weekend....

But if you run it on small server, ie Windows
2000/XP with less than 1GB memory, Teradata performance is aweful. It hangs
from time to time and even some simple query takes considerable time, while
Oracle and Microsoft SQL Server never behave like that.

extreme parallelism:-) A
share-nothing architecture. and some specific software that takes advantage
of a hardware configuration.. It's pretty cool stuff for the high end
in size DB's. I have seen/performed several comparisons.. And when you are
spinning thru large result sets (millions of rows) - TD was the winner hands
down...
And it's rather expensive stuff. They provide specific
hardware along with the software. So they would be a Hardware/Software
vendor
Jonathan is correct - WalMart uses Teradata.
so what features does teradata have that
oracle doesnt for VLDBs?

If they did, then its a good thing that they didn't name it
"TeraFile".

Isn't Teradata what Walmart uses? From what I know,
it's
always been aimed at the market for really, really
big
databases. Hence the prefix "tera", which isn't so
big
anymore. Maybe they should rename the product
Petadata.
