Quite possibly, just for the effect of watching DSL gnash his teeth.
But seriously, there are lots of tradeoffs to be weighed up, and
SQL Server is quite probably worth considering. Oracle, properly
tuned, is a real high performance database (it gives you complete
control over where you lay out certain tablespaces, so say you
have an index that's getting hit heavily, you can move it to a
separate file system / I/O channel), but that comes at a high
performance cost - it ain't cheap. SQL Server is built on Sybase,
IIRC (either that or Ingres; I get the two confused), so it's an OK
database with GUI-fied front end, which probably means MCSE-like
DBA's will be a dime a dozen. I don't know what it would be like

I'd never point anything like a database server directly out onto
the 'net. They're just too complicated to secure properly, both
from an administrative and in a secure-application sense. If you
need direct access to the database (e.g., SQL), then a VPN would
be the way to go, otherwise access the data through a front end

Bear in mind that, except for large result sets, XML may increase
the amount of padding around your data, unless you employ some sort
of datalink compression.
I find XML useful for foreign interfaces, and am more than content to
use [OJ]DBC (or the equivalent interface drivers) for an integrated

And that, I personally feel, is the downfall of most HTML-based apps.
(Generalising a bit here) They look like web based applications, they
run slowly over dialup links (and often require multiple trips to the
server, especially if validation can't be performed locally using
But that's definitely just my opinion, and can be treated as such ...
