I have been waiting for sooooo long for this, I just want to hear these words by Celko himself "Rows are not records; fields are not columns; tables are not files."
You can get the podcast here http://www.sqldownunder.com/, it is show number 21 and in this show Celko discusses SQL coding and multiprocessing futures
For those of you who don't know who Joe Celko is, here is a small list
Celko always answers very polite in newsgroups (yeah right)
Celko is the author of SQL for Smarties
Celko coined the term Lasagna Code
And last but not least Celko has participated on the ANSI X3H2 Database Standards Committee, and helped write the SQL-89 and SQL-92 standards
