СКАЧАТЬ Database Design and Relational Theory: Normal Forms and All That Jazz, 2nd Edition БЕСПЛАТНО EPUB - DOC - DJVU - RTF - PDFОписание: Создайте конструкцию базы данных, которая масштабируется, отвечает требованиям бизнеса, и по своей сути работы поддерживает ваши данные структурированными и годнымы к употреблению в условиях изменений бизнес-модели и программных систем. Эта книга о теории проектирования баз данных. Теория проектирования - это научная основа для проектирования баз данных, так же, как реляционная модель является научной основой для технологии баз данных в целом.Базы данных лежат в основе так многого, что мы делаем в компьютерном мире, что негативные последствия плохой конструкции могут распространиться чрезвычайно широко.
Create database designs that scale, meet business requirements, and inherently work toward keeping your data structured and usable in the face of changing business models and software systems. This book is about database design theory. Design theory is the scientific foundation for database design, just as the relational model is the scientific foundation for database technology in general. Databases lie at the heart of so much of what we do in the computing world that negative impacts of poor design can be extraordinarily widespread.
This second edition includes greatly expanded coverage of exotic and little understood normal forms such as: essential tuple normal form (ETNF), redundancy free normal form (RFNF), superkey normal form (SKNF), sixth normal form (6NF), and domain key normal form (DKNF). Also included are new appendixes, including one that provides an in-depth look into the crucial notion of data consistency. Sequencing of topics has been improved, and many explanations and examples have been rewritten and clarified based upon the author’s teaching of the content in instructor-led courses.
This book aims to be different from other books on design by bridging the gap between the theory of design and the practice of design. The book explains theory in a way that practitioners should be able to understand, and it explains why that theory is of considerable practical importance. Reading this book provides you with an important theoretical grounding on which to do the practical work of database design. Reading the book also helps you in going to and understanding the more academic texts as you build your base of knowledge and expertise. Anyone with a professional interest in database design can benefit from using this book as a stepping-stone toward a more rigorous design approach and more lasting database models.
What You Will Learn:
Understand what design theory is and is not
Be aware of the two different goals of normalization
Know which normal forms are truly significant
Apply design theory in practice
Be familiar with techniques for dealing with redundancy
Understand what consistency is and why it is crucially important
Who This Book Is For:
Those having a professional interest in database design, including data and database administrators; educators and students specializing in database matters; information modelers and database designers; DBMS designers, implementers, and other database vendor personnel; and database consultants. The book is product independent.
