Database Administration, Second Edition, is the definitive, technology-independent guide to the modern discipline of database administration. Packed with best practices and proven solutions for any database platform or environment, this text fully reflects the field's latest realities and challenges. Drawing on more than thirty years of database experience, Mullins focuses on problems that today's DBAs actually face, and skills and knowledge they simply must have.
Mullins presents realistic, thorough, and up-to-date coverage of every DBA task, including creating database environments, data modeling, normalization, design, performance, data integrity, compliance, governance, security, backup/recovery, disaster planning, data and storage management, data movement/distribution, data warehousing, connectivity, metadata, tools, and more.
This edition adds new coverage of "Big Data," database appliances, cloud computing, and NoSQL. Mullins includes an entirely new chapter on the DBA's role in regulatory compliance, with substantial new material on data breaches, auditing, encryption, retention, and metadata management. You'll also find an all-new glossary, plus up-to-the-minute DBA rules of thumb.
Rezensionen / Stimmen
"I've forgotten how many times I've recommended this book to people. It's well written, to the point, and covers the topics that you need to know to become an effective DBA."
-Scott Ambler, Thought Leader, Agile Data Method
"This is a well-written, well-organized guide to the practice of database administration. Unlike other books on general database theory or relational database theory, this book focuses more directly on the theory and reality of database administration as practiced by database professionals today, and does so without catering too much to any specific product implementation. As such, Database Administration is very well suited to anyone interested in surveying the job of a DBA or those in similar but more specific roles such as data modeler or database performance analyst."
-Sal Ricciardi, Program Manager, Microsoft
"One of Craig's hallmarks is his ability to write in a clear, easy-to-read fashion. The main purpose of any technical book is to transfer information from writer to reader, and Craig has done an excellent job. He wants the reader to learn-and it shows."
-Chris Foot, Manager, Remote DBA Experts and Oracle ACE
"A complete and comprehensive listing of tasks and responsibilities for DBAs, ranging from creating the database environment to data warehouse administration, and everything in between."
-Mike Tarrani, Computer Consultant
"I think every business manager and every IT manager should have a copy of this book."
-Dan Hotka, Independent Consultant and Oracle ACE
"This book by Craig Mullins is wonderfully insightful and truly important. Mullins describes the role and duties of data administrators and database administrators in modern organizations with remarkable insight and clarity."
-Michael Tozer, Author and former U.S. Navy officer
