Anyone can explain to me what is suddenly so wrong about relational database with hierarchical indexing?
Absolutely nothing.
Someone brought up LDAP earlier. In fact, Netscape's LDAP server is built atop a special version of DB2 with highly optimized indexing.
The question of using a heirarchal database (whether LDAP or XML) vs. your own custom-built relational indexes boils down to (IMHO) the problem at hand and its tolerance for speed vs. integration stress vs. budget.
Well if you're going upto 100 Million rows, you probably arn't using an RDMS. You'll probably be relying on some very big iron and a bespoke database to handle your data
Actually, DB2 on AIX on a big-ass whopping machine (sorry -- can't remember the specs -- but it was huge) easily handled 60-80 million rows in a well-tuned and well-index table. As long as the SQL queries took advantage of the indexs.. when they didn't, there were problems.
I would love if Linux could do that. Finding AIX admins is a real pain.
IBM has starting doing research to get DB2 running *equally* as well on Linux as it does on AIX. Of course, DB2 runs fine for most installs on Linux but for a large RDBMS (of data warehouse size) the perception is that DB2 must run on AIX to perform well. IBM has been trying (and I'm sure it will take some time) to level the playing field. Perhaps, IBM wants to phase out their own AIX and replace it with Linux?
Now I'm one semester away from graduation, with a 3.5 average overall and a lackluster 3.0 in CS, and I'm liking it less and less every day.
Don't compare school and the real world as they are very different entities. I spent many a night in the CS labs thinking the same things. I also finished with a measly 3.2 average in CS. I hated CS and dreaded spending my entire career doing it.
Guess what? No one cares about your GPA. It is irrevelent. No one cares how well you can bubble sort, whatever. Its how you *think* that matters and its *thinking* that's really fun. In school, exams and homework are planned drudgery written by some hack professor.
Since I've starting working, I've actually had fun as a Developer (6 years). At times, it has sucked, but that's the case with any job. But, overall its fun. What makes it fun IMHO is *thinking* and *learning* on my own. I have actually enjoyed some of the crap my employeers have shoveled at me (such as *cringe* COBOL) just because I new absolutely nothing about it.
My advice: Just get through school. Don't try to get A's... shoot for B's and spend all the extra time that you would be normally be cramming doing something fun like smoking pot or drinking beer. Then, get a job you think sounds interesting and learn everything you can about it. It's a totally different world. A much better world.

Swing has more commercial applications written in it now than ever (JBuilder, AppGen, and basically everything from TogetherSoft is just the tip of the iceberg and are just to name a few).
Yes, 10 is greater than 0.
The few commercial SWING apps that do exist are used primarily by Java developers (JBuilder, TogetherJ, etc). Coincidence?
I think not.
SWING starts slow (despite HotSpot), eats up a whole bunch of memory (more than M$ bloatware), and then continues to run slow. It is not, and, IMHO, never will be ready for wide-scale use by the masses.
For what its worth, I work in a Java-mostly software development company and have been profesionally developing in Java since 1.0 ('97).
I agree that Qwest is under no legal obligation to do anything.
But, any corporation doing business in America in this day and age should realize that 99% of the time it is better to suck it up and take a minor monetary short term loss than *risk* offending potential long-term customers. Once a company gets a reputation for poor service, its real hard to change it.
As much as I hate to say it, Qwest should give refunds for the customers who ask for it. Any business should know that "The Customer is always right".
McDonald's provides a good example of this. The great Monopoly game scandel was not their fault, but immediately after news of the scandel broke,
they offered a new $10 million dollar contest. Instead of claiming, "its not their fault", they said they were sorry, toke a minor slap on the wrist, and ended the bad press immediately.
Qwest should do the same. They should just quietly give refunds to the customers who ask for them. Millions of retails companies across the country give refunds every day. Its part of the cost of running a successful business. Tech companies that don't realize this will go out of business (unless they are a monoply, of course).

we have some > 10,000 entries for articles now
I think the original post is getting at MUCH larger numbers. Larger as in >100 million rows
in a table. Perhaps even bigger.
