My time with DB2/LUW has been with community edition (free-ish) 11.5 for some time. Fact is, I acquired this M900 (IBM) pc to outfit it with 16 gig of memory, which is the max supported in 11.5. Since I'm going through the agony of upgrading ubuntu (the image has been moved from 8.04 onward, with the original root partition too small to upgrade further; new machine cloned drive, and so on). So it seemed opportune to have another look at DB2. Imagine my surprise to find the max memory support has been cut to 8 gig in today's shipping edition. They, of course, spin this as a favor to users. Yeah, right.
By most accounts/metrics, DB2 is at the back of the RDBMS pack. They invented the damn thing! So they shoot themselves in the foot. PG is ok, but it's a process model database. MySql is not so ok, what with the corporate nonsense.
IFF AI, as currently implemented, can intuit Special Relativity from just a clock tower and a moving tram will I take AI seriously.
Infinite granularity yields infinite complexity.

The world is not linear.

Power tends to corrupt; absolute power corrupts absolutely.

We have a golden share, which I control, or the president controls. Now I'm a little concerned whoever the president might be, but that gives you total control.

There's not a single example of things working out for the appeaser.

I have had to explain and re-explain and re-explain and re-explain, you know, how relational databases work, what is an eigenvector,
what is dimensionality reduction.
-- Christopher Wylie/2018
... but Flash-based storage has such a different performance profile from rotating media, that I suspect that it will end up having
a large impact on filesystem design. Right now, most filesystems tend to be designed with the latencies of rotating media in mind.

This Week's thought
If you think this is not dangerous, just keep in mind that the Trump Organization Inc. over the years filed for Chapter 11 bankruptcy protection for six different businesses. There was a reason for that: the operating style and values of its boss. -- Thomas L. Friedman/2025
See you next week in a brand new show©Heckle and Jeckle
In a time of SSD, multi-core/processor, two terabyte memory and Optane App Direct Mode (RIP) machines, there is no reason
not to build from BCNF data. Time to do what Dr. Codd demonstrated. Technology has finally caught up with the maths.

Shameless Plug
I know a little something about SQL, DB2 (preferably LUW, z/OS if the money's right), Oracle, SQL Server, Postgres, and database design in general. Mentoring/teaching/consulting on a short term basis, too. And a bit of stat analysis if it's R.
