Occasional musings on the primacy of the relational model, database, quants and silliness of all things xml.
... 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
You can put cat shit in a sugar cone, but that doesn't make it chocolate ice cream. -- Donald Hughes McElhone, Ph.D.[statistics, Iowa State]/1975
That R&R's work was not many times replicated in this sense may be best understood as demonstrating how far the current modus vivendi for social science/economics/policy sciences still is from real science. -- Mike Rappeport/2013
The world is not linear. -- McElhone/op cit
When you're dead, you're dead. Until then, there's ice cream. -- Patrick Jane/2011
Therefore: In a time of SSD multi-core/processor 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. gnuoytr at rcn dot com.
