There is much ado about the Sun/IBM marriage these days, and I have made my contributions elsewhere, so it is time to do so here.
The issue that concerns me is MySql. On the surface, Sun spending $1 billion for it made no sense at the time, and now we have the Drizzle-ing off of what makes a RDBMS worth having:
Aker has already selected particular functionality for removal: modes, views, triggers, prepared statements, stored procedures, query cache, data-conversion inserts, access control lists and some data types. (Chris Duckett on zdnet/24 jul 2008)
That report says InnoDB is/will be included. Hmmm.
What I see happening if this goes through, IBM will roll up the MySql name and ship DB2 for COBOL-z/OS. I don't see IBM shipping an Oracle bit of kit (InnoDB) with "it's" database. At the same time, conversions of COBOL/VSAM applications (I have been involved in a few) typically are done for the purpose of _looking_ like the new application is a database system, but all of the ACID remains in the COBOL (no reason to get rid of that, it works. riiiiiiiiiiiiiiight). Classic MySql (up through about 4.0) was just a sql parser in front of the file system.
This is really all that the COBOL coders want, anyway. They don't understand ACID or Normal Forms. For marketing purposes, the Pointy Haired Bosses need to say that their 40 year old code is really Brand New and Updated to Modern Technology (sql:92 is modern by this definition), so off to DB2 it goes. But no one wants to think relationally. Real DB2 for z/OS does included the proper kit to build a proper application, but I have never seen any of that used.
MySql gives them the perfect (or perverse, depending) answer: DB2 of COBOL-z/OS. Coming to a shop near you. Real soon now.
IFF AI, as currently implemented, can intuit Special Relativity from just a clock tower and a moving tram will I take AI seriously.

[T]he massive push to relocate federal jobs outside the Beltway comes with the risk of kneecapping agencies through the loss of experienced workers and bogging them down in logistical minutia.

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. -- Dr. McElhone/1974

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
[Scotland's HPV] vaccination program began in 2008, and so far the women who were vaccinated as 12- or 13-year-olds have shown not one single case of cervical cancer. And the rate in women who were vaccinated at later ages was 80% lower than the unvaccinated. Cervical cancer is almost completely preventable through such vaccination programs, and the anti-vaccine activists who have come out against them (such as the dangerous fool nominated to be secretary of HHS) can go to hell. -- Derek Lowe/2024 [the morons will be running the asylum, if we let them]
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 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.
