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
The world is not linear. -- Dr. D.H. McElhone (Ph.D., Math Stats Iowa State)/1975
The 4114 chip error was common (1986-1988) knowledge - especially as they were in ICBM's at the time which would 'ready' themselves without instruction! -- Wiki article about TI-990 minicomputer
If your business doesn't make you the amount of money you think you deserve, sell out and go to work for wages like the rest of us. -- My Pappy/1970
If you're on food stamps, the average family has about $3 to spend on dinner. For that you can get about 3,700 calories' worth of soda, crackers, cookies and snacks, or you can get 300 or 320 calories of fruits and vegetables. It's economically rational to feed your kids junk. -- Doug Rauch/2013
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.
