E. F. Codd's relational model of data has been described as one of the three greatest inventions of all time (the other two being agriculture and the scientific method), and his receipt of the 1981 ACM Turing Award-the top award in computer science-for inventing it was thoroughly deserved. The papers in which Codd first described his model were staggering in their originality; they had, and continue to have, a huge impact on just about every aspect of the way we do business in the world today. And yet few people, even in the professional database community, are truly familiar with those papers. This book is an attempt to remedy this sorry state of affairs. In it, well known author C. J. Date provides a detailed examination of all of Codd's major technical publications, explaining the nature of his contribution in depth, and in particular highlighting not only the many things he got right but also some of the things he got wrong.
Describes influential business philosophies and marketing ideas from the past twenty years and examines why they did not work.
E. F. Codd’s relational model of data has been described as one of the three greatest inventions of all time (the other two being agriculture and the scientific method), and his receipt of the 1981 ACM Turing Award, the top award in computer science, for inventing it was thoroughly deserved. The papers in which Codd first described his model were staggering in their originality; they had, and continue to have, a huge impact on just about every aspect of the way we do business in the world today. And yet few people, even in the professional database community, are truly familiar with those papers. This book—a thorough overhaul and rewrite of an earlier book by the same name—is an attempt to remedy this sorry state of affairs. In it, well known author C. J. Date provides a detailed examination of all of Codd’s major database publications, explaining the nature of his contribution in depth, and in particular highlighting not only the many things he got right but also some of the things he got wrong. Database theory and practice have evolved considerably since Codd first defined his relational model, back in 1969. This book draws on decades of experience to present the most up to date treatment of the material possible. Anyone with a professional interest in databases can benefit from the insights it contains. The book is product independent.
In a gesture toward traditional First Nations orality, Peter Cole blends poetic and dramatic voices with storytelling. A conversation between two tricksters, Coyote and Raven, and the colonized and the colonizers, his narrative takes the form of a canoe journey. Cole draws on traditional Aboriginal knowledge to move away from the western genres that have long contained, shaped, and determined ab/originality. Written in free verse, Coyote and Raven Go Canoeing is meant to be read aloud and breaks new ground by making orality the foundation of its scholarship. Cole moves beyond the rhetoric and presumption of white academic (de/re)colonizers to aboriginal spaces recreated by aboriginal peoples. Rather than employing the traditional western practice of gathering information about exoticized other, demonized other, contained other, Coyote and Raven Go Canoeing is a celebration of aboriginal thought, spirituality, and practice, a sharing of lived experience as First Peoples.

What is the best way to define the police? Why do we have police at all? In modern democracies like the United States and Great Britain, why is most policing done by employees of the state? What is the relationship between police and the law? What makes a good police officer? In addressing these questions, Klockars makes the reader look at the idea of police from a new perspective. First he explains how any definition of police must include the reality of coercive force--the fact that police officers everywhere have the right to "forcibly compel other people to do something." Next he describes the evolution of the police in the United States vis-a-vis the police in Great Britain. After exploring the role of the detective, he highlights the moral conflicts and issues of discretion that police officers face daily. Finally, Klockars examines what makes a good police officer.

The author argues that the imperialist ideology and policies adopted by the Nazis must be seen as the result of a complex evolution of imperialist thinking in Germany which had its roots in the nineteenth century.

"Playwright Edwin Sanchez makes a promising New York debut with TRAFFICKING IN BROKEN HEARTS, a grim, streetwise and bracingly compassionate work ... he convinces with the honesty of his writing and a canny, thoughtful grasp of his trio of characters. The playwright does an especially effective job in penning the gray shades of his characters ..." -Greg Evans, Variety
