About a year ago, "A Ton of Bricks" told the story of Amazon's conversion, as yet still not discussed in the channels I follow, from e-tailer to brick-and-mortar retailer. Well, the conversion continues apace. Amazon's P/E ratio, as I type, is 3,182. They make a few pennies on the share. That Amazon is able to convince so many that it has found the New Way is astounding. The cost of jet transport, per pound, is so much higher than rail, it's clear now that Amazon is finally admitting what OR folks have known for decades: JIT production is fine when one is dealing with very high value parts which are small in volume, light in weight, and a small part of the BOM. In such an instance, stockpiling can add up to more in carrying cost than transport. For garden variety retail, warehousing wins. Always has and always will; so long as fuel isn't free.
Amazon isn't such a manufacturing business. It's a distributor, and its main cost is transport. The main cost it can control, at least. Unless Jeff decides to go all Walton on its suppliers. But, since Amazon has set out to be the purveyor of everything, that ain't gonna happen.
Despite what the reactionaries assert, the world is not flat nor is it hierarchical. The world is relational. Infinite granularity yields infinite complexity.

Scientists aren't vocal enough about science. There are large groups of people who think scientists are all frauds and who don't
believe in science, and they're being cultured by some of our far right-wing politicians, religious leaders and community leaders. -- Drew Weissman/2022
To date, Microsoft is stating that organizations testing In-Memory OLTP have
seen transaction speeds improve by up to 30 times compared to past
performance, with the best performance gains achieved when the business
logic resides in the database and not in the applications.

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.

... 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
Investigative reporters are an idiosyncratic breed of journalist. Typically fearless, they are often a source of angina to their editors. Mr. Walsh was no exception. -- Michael S. Rosenwald/2024 [no surprise - I spent a bit of time on Jack Anderson's staff]
In a time of SSD, multi-core/processor, two terabyte memory and Optane App Direct Mode 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.

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.
