Book Synopsis E. F. Codd and Relational Theory: A Detailed Review and Analysis of CoddÕs Major Database Writings by : C. J. Date
Download or read book E. F. Codd and Relational Theory: A Detailed Review and Analysis of CoddÕs Major Database Writings written by C. J. Date and published by Lulu.com. This book was released on 2019-07-18 with total page 306 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 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.
Book Synopsis Fifty Years of Relational, and Other Database Writings by : C.J. Date
Download or read book Fifty Years of Relational, and Other Database Writings written by C.J. Date and published by Technics Publications. This book was released on with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty years of relational. It’s hard to believe the relational model has been around now for over half a century! But it has—it was born on August 19th, 1969, when Codd’s first database paper was published. And Chris Date has been involved with it for almost the whole of that time, working closely with Codd for many years and publishing the very first, and definitive, book on the subject in 1975. In this book’s title essay, Chris offers his own unique perspective (two chapters) on those fifty years. No database professional can afford to miss this one of a kind history. But there’s more to this book than just a little personal history. Another unique feature is an extensive and in depth discussion (nine chapters) of a variety of frequently asked questions on relational matters, covering such topics as mathematics and the relational model; relational algebra; predicates; relation valued attributes; keys and normalization; missing information; and the SQL language. Another part of the book offers detailed responses to critics (four chapters). Finally, the book also contains the text of several recent interviews with Chris Date, covering such matters as RM/V2, XML, NoSQL, The Third Manifesto, and how SQL came to dominate the database landscape.

Book Synopsis Elements of Relational Database Design by : David C. Hopkins
Download or read book Elements of Relational Database Design written by David C. Hopkins and published by Trafford Publishing. This book was released on 2010 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise presentation of the basic principles of database design. It deals with the widely accepted core definitions and conclusions that can be precisely stated and proven. Most of the topics covered are essential to the concluding chapter on â oenormalizationâ â " a knowledge of which is crucial for avoiding problematic database designs. In addition to brevity, the structure of the book is meant to minimize page turning by making it unnecessary to flip back to previous pages. For example, to allow the reader to view all the information on a topic at once, the text appears on the left and the corresponding examples on the right of facing pages. The book consists of five chapters as follows: The first two describe the basic techniques of modeling the real world with a database. Chapter Three covers common â oeoperationsâ one can do with a database. Most of these operations pertain to using rather than designing a database; however, a few of them are also crucial for design. â oeDependency and decompositionâ â " important in their own right and also required for the final chapter â " receive a comprehensive treatment in Chapter Four. The book concludes with Chapter Five's coverage of normalization where the levels of good database design are defined along with procedures for attaining these levels. Also, problems that can occur when a database is not at a given level are described and illustrated by examples.
Book Synopsis Database Explorations by : C. J. Date
Download or read book Database Explorations written by C. J. Date and published by Trafford Publishing. This book was released on 2010-07 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: A note from the authors: Dear Reader: "Database is boring." That sentiment is heard all too widely these days. But it's so wrong! The database field is full of important problems still to be solved and interesting issues still to be examined - and some of those problems and issues are explored in this book. Between us, we have nearly 80 years experience in this field, and we're still actively researching, exploring, and learning, as well as helping others do the same. The present book is the latest in a series devoted to these goals; using "The Third Manifesto" (a detailed proposal for the future of database technology) as a foundation, it reports on some of our most recent investigations in this field. Among many other things, it includes the most recent version of "The Third Manifesto" itself; specifications for a conforming language called Tutorial D; and a detailed proposal for a model of type inheritance. Other significant features include: - Extending the foreign key concept - Simplifying queries using image relations - Closer looks at logic and relational algebra - Suggested approaches to "missing information" - Responses to certain "Manifesto" criticisms - Clarifying aspects of normalization The tone of the book overall is naturally somewhat serious, but there are moments of light relief as well. We hope you enjoy it. C.J. Date and Hugh Darwen

Book Synopsis SQL and Relational Theory by : C.J. Date
Download or read book SQL and Relational Theory written by C.J. 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.

Book Synopsis Database Dreaming Volume II by : C. J. Date
Download or read book Database Dreaming Volume II written by C. J. Date and published by Technics Publications. This book was released on 2022-02-11 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along with its companion volume (Database Dreaming Volume I), this book offers a collection of essays on the general topic of relational databases and relational database technology. Most of those essays, though not all, have been published before, but only in journals and magazines that are now hard to find or in books that are now out of print. Here’s a lightly edited excerpt from the preface (so this is the author speaking): I went back and reviewed all of those early essays, looking for ones that seemed worth reviving (or, rather, revising and reviving) at this time. Of course, some of them definitely weren’t! However, out of a total of around 130 original papers, I did find some 20 or so that seemed to me worth preserving and hadn’t already been incorporated in, or superseded by, more recent books of mine. So I tracked down the original versions of those 20 or so papers and set to work. When I was done, though, I found I had somewhere in excess of 600 pages on my hands—too much, in my view, for just one book, and so I split them across two separate volumes. Highlights of the present volume include a detailed explanation of the multiple assignment operator and why it’s so essential; an investigation into why object and database technologies are so much more different than they’re often made out to be; a critical examination of SQL’s support for pointers (“references”); a tutorial on the counterintuitive (but crucial) concept of tables with no columns; and an annotated and extended debate between the author and E. F. Codd, inventor of the relational model, on the subject of nulls and three-valued logic.

Book Synopsis Type Inheritance and Relational Theory by : C.J. Date
Download or read book Type Inheritance and Relational Theory written by C.J. Date and published by "O'Reilly Media, Inc.". This book was released on 2016-09-08 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Type inheritance is that phenomenon according to which we can say, for example, that every square is also a rectangle, and so properties that apply to rectangles in general apply to squares in particular. In other words, squares are a subtype of rectangles, and rectangles are a supertype of squares. Recognizing and acting upon such subtype / supertype relationships provides numerous benefits: Certainly it can help in data modeling, and it can also provide for code reuse in applications. For these reasons, many languages, including the standard database language SQL, have long supported such relationships. However, there doesn’t seem to be any consensus in the community at large on a formal, rigorous, and abstract model of inheritance. This book proposes such a model, one that enjoys several advantages over other approaches, not the least of which it is that it’s fully compatible with the well known relational model of data. Topics the model covers include: Both single and multiple inheritance Scalar, tuple, and relation inheritance Type lattices and union and intersection types Polymorphism and substitutability Compile time and run time binding All of these topics are described in detail in the book, with numerous illustrative examples, exercises, and answers. The book also discusses several alternative approaches. In particular, it includes a detailed discussion and analysis of inheritance as supported in the SQL standard.
