Dr. Codd Was Right: A Hop, A Skip, and A Jump

Vaccinated ≠ Not Infectious

Covid-19 has killed at least 1,123,836 people (as of 20 March 2023, final update)

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.
-- Jonathan Watts/2015 [my emphasis]

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.

-- Linus Torvalds/2007

I believe quite strongly that, if you think about the issue at the appropriate level of abstraction, you're inexorably led to the position that databases must be relational.

-- Chris Date/2009

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]

Therefore:

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.

A Hop, A Skip, and A Jump - part the third

Some more spelunking. Turns out that linux and Windows have existing mechanisms to leverage persistent memory under the covers of block-mode IO; i.e. mmap and DAX. Such might be sufficient to get by in the short term. Here's Intel's report.

Both Windows* and Linux* support memory-mapped files, a feature which has been around for a long time, but is not commonly used.

Interestingly, the BDFL of Progress database said, around 1990, that if your database didn't use mmap, get another database. That long ago.

Intel also has a FAQ, which has some interesting tidbits.
