True: I am "applied math" rather than theory.

NO! My books are ANSI/ISO Standard, not SQL Server, Oracle, DB2, or any other product related. I deviate only when a non-standard feature is common enough it will port (CREATE INDEX in the X\OPEN syntax, math functions, some string functions, etc.).
I have been approached by a few vendors to do a "JOE CELKO'S <product name here> FOR SMARTIES" book, but I have not done so. It is a matter of professional ethics, not knowing enough about the products and no bribes big enough (yet).
I also deal with things at a data level -- design of encoding schemes, statistical analysis, risk and error analysis, data quality and validation, etc. My first Masters degree was in math and I have worked as a full-time statistician and scientific programmer before I became "the SQL Guy" and stopped doing honest work.
