Quoting from that tribute: "Dr. Codd single-handedly put the field of database management on a solid scientific footing. The entire relational database industry, now worth many billions of dollars a year, owes its existence to Ted's original work. The same is true of all relational database research and teaching programs in universities and similar organizations worldwide. Indeed, all of us who work in this field owe our careers and livelihoods to Ted's contributions from the late 1960s to the early 1980s."

From the publisher: "Written by the originator of the relational model, this book covers the practical aspects of the design of relational databases. The author defines twelve rules that database management systems need to follow in order to be described as truly relational and then gives the motivation behind these rules. This book is a perfect resource for students and professionals in the field." From Wikipedia: "The relational model (RM) is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, where all data are represented in terms of tuples, grouped into relations. A database organized in terms of the relational model is a relational database The relational model was developed by Edgar F. Codd Some years after publication of his 1970 model, Codd proposed a three-valued logic (True, False, Missing/NULL) version of it to deal with missing information, and in his The Relational Model for Database Management Version 2 (1990) he went a step further with a four-valued logic (True, False, Missing but Applicable, Missing but Inapplicable) version.".
