A sourceforge project does not a phenomenon make. I guess when the
banks and airlines have our data in the XML files, and I don't mean a
few hybrid patchwork examples, I mean the hardcore permanent
long-term stuff as well as the transactional support for the
reservations we're making all day. When that happens, we'll start
picking the restaurants.
I've never said native XML databases will replace the old-school apps
like banking accounts that fit relational databases very well. What
they will do is enable new applications that simply cannot be built on
top of a relational database, applications like Safari (the book site,
not the web browser):
http://safari.oreilly.com/
There are others, mostly in publishing because that's the first area
where there's a large backlog of information and applications that
relational database vendors have been unable to serve. However other
companies will come online as they begin to realize they can manage
all their data with these tools, not just the the 20% of it that fits
neatly into rectangles. Expect to see more uptake in law firms,
advertising, media, education, government, and other sectors that have
large numbers of critical documents where order matters, duplication
is a fact of life, and normalization is not just a bad idea out
outright impossible.
The relational model is a very powerful model, but it achieves its
power at the cost of restricting what it's possible to store. Other
models are needed for other applications.
Two words: document management.
