SQL is full of difficulties and traps for the unwary. You can avoid them if you understand relational theory, but only if you know how to put the theory into practice. In this insightful book, author C.J. Date explains relational theory in depth, and demonstrates through numerous examples and exercises how you can apply it directly to your use of SQL. This second edition includes new material on recursive queries, “missing information” without nulls, new update operators, and topics such as aggregate operators, grouping and ungrouping, and view updating. If you have a modest-to-advanced background in SQL, you’ll learn how to deal with a host of common SQL dilemmas. Why is proper column naming so important? Nulls in your database are causing you to get wrong answers. Why? What can you do about it? Is it possible to write an SQL query to find employees who have never been in the same department for more than six months at a time? SQL supports “quantified comparisons,” but they’re better avoided. Why? How do you avoid them? Constraints are crucially important, but most SQL products don’t support them properly. What can you do to resolve this situation? Database theory and practice have evolved since the relational model was developed more than 40 years ago. SQL and Relational Theory draws on decades of research to present the most up-to-date treatment of SQL available. C.J. Date has a stature that is unique within the database industry. A prolific writer well known for the bestselling textbook An Introduction to Database Systems (Addison-Wesley), he has an exceptionally clear style when writing about complex principles and theory.

“Startling and astringently poetic.” —The New York Times A literary discovery: an extraordinary account, in the tradition of The House on Mango Street and Angela’s Ashes, of a Colombian woman’s harrowing childhood This astonishing memoir was hailed as an instant classic when first published in Colombia in 2012, nearly a decade after the death of its author, who was encouraged in her writing by Gabriel García Márquez. Comprised of letters written over the course of thirty years, and translated and introduced by acclaimed writer Daniel Alarcón, it describes in vivid, painterly detail the remarkable courage and limitless imagination of a young girl growing up with nothing. Emma Reyes was an illegitimate child, raised in a windowless room in Bogotá with no water or toilet and only ingenuity to keep her and her sister alive. Abandoned by their mother, she and her sister moved to a Catholic convent housing 150 orphan girls, where they washed pots, ironed and mended laundry, scrubbed floors, cleaned bathrooms, sewed garments and decorative cloths for the nuns—and lived in fear of the Devil. Illiterate and knowing nothing of the outside world, Emma escaped at age nineteen, eventually establishing a career as an artist and befriending the likes of Frida Kahlo and Diego Rivera as well as European artists and intellectuals. The portrait of her childhood that emerges from this clear-eyed account inspires awe at the stunning early life of a gifted writer whose talent remained hidden for far too long. For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world. With more than 1,800 titles, Penguin Classics represents a global bookshelf of the best works throughout history and across genres and disciplines.

More Precisely provides a rigorous and engaging introduction to the mathematics necessary to do philosophy. It is impossible to fully understand much of the most important work in contemporary philosophy without a basic grasp of set theory, functions, probability, modality and infinity. Until now, this knowledge was difficult to acquire. Professors had to provide custom handouts to their classes, while students struggled through math texts searching for insight. More Precisely fills this key gap. Eric Steinhart provides lucid explanations of the basic mathematical concepts and sets out most commonly used notational conventions. Furthermore, he demonstrates how mathematics applies to many fundamental issues in branches of philosophy such as metaphysics, philosophy of language, epistemology, and ethics.

Zero has been axial in human development, but the origin and discovery of zero has never been satisfactorily addressed by a comprehensive, systematic and above all interdisciplinary research program. In this volume, over 40 international scholars explore zero under four broad themes: history; religion, philosophy & linguistics; arts; and mathematics & the sciences. Some propose that the invention/discovery of zero may have been facilitated by the prior evolution of a sophisticated concept of Nothingness or Emptiness (as it is understood in non-European traditions); and conversely, inhibited by the absence of, or aversion to, such a concept of Nothingness in the West. But not all scholars agree. Join the debate.

The Washington Post Notable Non-Fiction of 2013 “I can imagine few more enjoyable ways of thinking than to read this book.”—Sarah Bakewell, New York Times Book Review, front-page review Tackling the “darkest question in all of philosophy” with “raffish erudition” (Dwight Garner, New York Times), author Jim Holt explores the greatest metaphysical mystery of all: why is there something rather than nothing? This runaway bestseller, which has captured the imagination of critics and the public alike, traces our latest efforts to grasp the origins of the universe. Holt adopts the role of cosmological detective, traveling the globe to interview a host of celebrated scientists, philosophers, and writers, “testing the contentions of one against the theories of the other” (Jeremy Bernstein, Wall Street Journal). As he interrogates his list of ontological culprits, the brilliant yet slyly humorous Holt contends that we might have been too narrow in limiting our suspects to God versus the Big Bang. This “deft and consuming” (David Ulin, Los Angeles Times) narrative humanizes the profound questions of meaning and existence it confronts.
