Download or read book Time and Relational Theory written by C.J. Date and published by Morgan Kaufmann. This book was released on 2014-08-13 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time and Relational Theory provides an in-depth description of temporal database systems, which provide special facilities for storing, querying, and updating historical and future data. Traditionally, database management systems provide little or no special support for temporal data at all. This situation is changing because: - Cheap storage enables retention of large volumes of historical data in data warehouses - Users are now faced with temporal data problems, and need solutions - Temporal features have recently been incorporated into the SQL standard, and vendors have begun to add temporal support to their DBMS products Based on the groundbreaking text Temporal Data & the Relational Model (Morgan Kaufmann, 2002) and new research led by the authors, Time and Relational Theory is the only book to offer a complete overview of the functionality of a temporal DBMS. Expert authors Nikos Lorentzos, Hugh Darwen, and Chris Date describe an approach to temporal database management that is firmly rooted in classical relational theory and will stand the test of time. This book covers the SQL:2011 temporal extensions in depth and identifies and discusses the temporal functionality still missing from SQL. - Understand how the relational model provides an ideal basis for taming the complexities of temporal databases - Learn how to analyze and evaluate commercial temporal products with this timely and important information - Be able to use sound principles in designing and using temporal databases - Understand the temporal support recently added to SQL with coverage of the new SQL features in this unique, accurate, and authoritative reference - Appreciate the benefits of a truly relational approach to the problem with this clear, user friendly presentation
Download or read book SQL and Relational Theory written by C. Date and published by "O'Reilly Media, Inc.". This book was released on 2011-12-16 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Relational Theory and the Practice of Psychotherapy written by Paul L. Wachtel and published by Guilford Press. This book was released on 2007-12-14 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and innovative book explores a new direction in psychoanalytic thought that can expand and deepen clinical practice. Relational psychoanalysis diverges in key ways from the assumptions and practices that have traditionally characterized psychoanalysis. At the same time, it preserves, and even extends, the profound understanding of human experience and psychological conflict that has always been the strength of the psychoanalytic approach. Through probing theoretical analysis and illuminating examples, the book offers new and powerful ways to revitalize clinical practice.

Download or read book View Updating and Relational Theory written by C.J. Date and published by "O'Reilly Media, Inc.". This book was released on 2012-12-20 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Views are virtual tables. That means they should be updatable, just as "real" or base tables are. In fact, view updatability isn’t just desirable, it’s crucial, for practical reasons as well as theoretical ones. But view updating has always been a controversial topic. Ever since the relational model first appeared, there has been widespread skepticism as to whether (in general) view updating is even possible. In stark contrast to this conventional wisdom, this book shows how views, just like base tables, can always be updated (so long as the updates don’t violate any integrity constraints). More generally, it shows how updating always ought to work, regardless of whether the target is a base table or a view. The proposed scheme is 100% consistent with the relational model, but rather different from the way updating works in SQL products today. This book can: Help database products improve in the future Help with a "roll your own" implementation, absent such product improvements Make you aware of the crucial role of predicates and constraints Show you how relational products are really supposed to behave Anyone with a professional interest in the relational model, relational technology, or database systems in general can benefit from this book.
Download or read book E F Codd and Relational Theory Revised Edition written by C. J. Date and published by Technics Publications. This book was released on with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Relational Psychoanalysis and Temporality written by Neil J. Skolnick and published by Routledge. This book was released on 2019-07-05 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes a foreword by Nancy McWilliams In Relational Psychoanalysis and Temporality, Neil J. Skolnick takes us on a journey that traces his personal evolution from a graduate student through to his career as a relational psychoanalyst. Skolnick uniquely shares his publications and presentations that span his professional career, weaving in issues around temporality and relational psychoanalysis. Accessible and deeply thought-provoking, this book explores the many ways our lives are pervaded and shaped by time, and how it infuses the problems that psychoanalysts work with in the consulting room. Skolnick begins each chapter with an introduction, contextualizing the papers in his own evolution as a relational analyst as well as in the broader evolution of the relational conceit in the psychoanalytic field. Following an incisive description of the realities and mysteries of time, he highlights how psychoanalysts have applied several temporal phenomena to the psychoanalytic process. The papers and presentations address an assortment of time-worn psychoanalytic issues as they have become redefined, reconfigured and re-contextualized by the application of a relational psychoanalytic perspective. It purports to chart the changes in the field and the author’s practice as, like many psychoanalysts, Skolnick explains his shifted perspective from classical to ego psychological, to relational psychoanalysis across the trajectory of his career. Finally, the author struggles to understand the contributions of time to the process of change in psychoanalytic thought and practice. This book also provides a fascinating guide to how our lives are contextualized in the invisibilities of time, illuminating the most frequent ways time influences psychoanalytic thinking and practice. Relational Psychoanalysis and Temporality will be of immense interest to psychoanalysts, psychoanalytic psychotherapists and therapists of all persuasions in their practice and training. It should also be of interest to philosophers, historians and scholars of psychoanalysis who have a general interest in studying the role of psychoanalysis in influencing contemporary trends of Western thought.

Download or read book Learning RFT written by Niklas Torneke and published by New Harbinger Publications. This book was released on 2010-11-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relational frame theory, or RFT, is the little-understood behavioral theory behind a recent development in modern psychology: the shift from the cognitive paradigm underpinning cognitive behavioral therapy to a new understanding of language and cognition. Learning RFT presents a basic yet comprehensive introduction to this fascinating theory, which forms the basis of acceptance and commitment therapy. The book also offers practical guidance for directly applying it in clinical work. In the book, author Niklas Törneke presents the building blocks of RFT: language as a particular kind of relating, derived stimulus relations, and transformation of stimulus functions. He then shows how these concepts are essential to understanding acceptance and commitment therapy and other therapeutic models. Learning RFT shows how to use experiential exercises and metaphors in psychological treatment and explains how they can help your clients. This book belongs on the bookshelves of psychologists, psychotherapists, students, and others seeking to deepen their understanding of psychological treatment from a behavioral perspective.

Download or read book The Theory and Practice of Relational Coaching written by Simon Cavicchia and published by Routledge. This book was released on 2018-07-27 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 'relational turn' is a movement affecting a range of disciplines including neuroscience, psychoanalysis, psychotherapy, organisational consulting and, more recently, coaching. Its primary focus is on the centrality of human relating in determining how individuals develop, make meaning and function individually and collectively. In The Theory and Practice of Relational Coaching: Complexity, Paradox and Integration, Simon Cavicchia and Maria Gilbert expand existing coaching theory and practice to focus on the implications of the relational turn for how coaches and clients think about the nature of identity, the self, change, learning, and individual and organisational development. Drawing on perspectives as varied as relational neuroscience, the relational foundations of personality development, psychoanalysis, psychotherapy, shame, vulnerability, complexity and systems ideas, the authors shed light on many of the paradoxes and challenges facing coaches and their clients in today’s fast-paced, volatile and uncertain organisational environments. These include holding tensions such as the uniqueness of individual needs with the requirements of organisational contexts, managing multiple stakeholder expectations and networks and balancing linear approaches to change with adjusting to emerging and unpredictable events. Given the ever-increasing volatility, complexity and uncertainty that coaches and their clients face, The Theory and Practice of Relational Coaching guides the reader through a series of illuminating perspectives, examples and practical suggestions. These will enable coaches to integrate a more relational orientation in their work and extend their range and that of their clients for responding creatively to the challenges of modern organisational life. The book will appeal to coaches and coaching psychologists in practice and training, as well as counsellors and psychotherapists retraining as coaches.

Download or read book Cartesian Spacetime written by E. Slowik and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although Descartes' natural philosophy marked an advance in the development of modern science, many critics over the years, such as Newton, have rejected his particular `relational' theory of space and motion. Nevertheless, it is also true that most historians and philosophers have not sufficiently investigated the viability of the Cartesian theory. This book explores, consequently, the success of the arguments against Descartes' theory of space and motion by determining if it is possible to formulate a version that can eliminate its alleged problems. In essence, this book comprises the first sustained attempt to construct a consistent `Cartesian' spacetime theory: that is, a theory of space and time that consistently incorporates Descartes' various physical and metaphysical concepts. Intended for students in the history of philosophy and science, this study reveals the sophisticated insights, and often quite successful elements, in Descartes' unjustly neglected relational theory of space and motion.
