Laid in is a copy of a 7-page National Academy of Sciences "Memorial Tribute" by C. J. Date. 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." The first page of that tribute feaures a facsimile of Codd's signature which nearly perfectly matches his actual signature in this book. Fine condition in a bright and shiny Near Fine dust jacket.

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.".
