Order papers targeted at the data professional/user who thinks critically and independently and appreciates a scientific approach, rather than follows the IT industry's fad-driven "cookbook mode". They offer accessible explanations the true relational technology—what we believe it would have been had  E.F. Codd completed his work—and the practical implications thereof. The papers outline McGoveran's re-interpretation of Codd's work that is consistent with the theoretical foundation of RDM and is distinct from the version that emerged in the industry after Codd's passing.

PRACTICAL DATABASE FOUNDATIONS ($35/paper)

 This series:

• Dispels common, misuse and abuse of data and relational fundamentals;
• Clarifies fundamental terminology, concepts and features of the real RDM that are ignored, distorted and misunderstood in the industry;
• Conveys the practical advantages of  RDM of which practitioners are unaware and/or which the industry has failed to deliver.
