THE DBDEBUNK GUIDE TO MISCONCEPTIONS ABOUT DATA FUNDAMENTALS Available to Order


When I discussed with a book publisher the idea of a guide/reference to misconceptions about data fundamentals, whose objective -- distinct from the usual cookbooks -- is to help data professionals base their practice on understanding, rather than cookbooks, he said "they are not interested in understanding, only in succeeding in their jobs". Apparently, the former is no longer a factor in the latter. Given the increasingly deteriorating experiences I had with publishers, it was time to stop bothering with them -- they pay and do very little -- and self-publish.

THE DBDEBUNK GUIDE TO MISCONCEPTIONS ABOUT DATA FUNDAMENTALS  - A DESK REFERENCE FOR THE THINKING DATA PROFESSIONAL AND USER is now available for purchase ($35, order via the BOOKS page (not to be confused with the RECOMMENDED BOOKS page); contact me by email for volume discounts).
