Michael writes with verve, authority, and an eminently readable style. What a rare delight to discover all this, and in a technical book too! When the sequel comes along, sign me up.” — Howard Katz, Owner, Fatdog Software Inc., Editor, XQuery from the Experts (Addison-Wesley, 2003) From corporate IT departments to academic institutions, XML has become the language of choice for storing and transmitting data across diverse application domains. XQuery, an XML Query Language invented by the World Wide Web Consortium, offers a powerful, standardized way to query all of that XML-encapsulated information. With its ability to integrate XML and non-XML data, XQuery seems poised to do for XML what SQL has done for relational data. Written by the Technical Lead for XML query processing at Microsoft, is an invaluable resource for XQuery novices and experts alike. For those new to XQuery, this example-rich text serves as a tutorial that brings readers quickly up to speed on XQuery's data model, type system, and core language features. More experienced XML and database developers will find an excellent reference on the nuances of various expressions, as well as a guide to using XQuery to accomplish specific tasks. XQuery: The XML Query Language Drawing on his experiences using XQuery, Michael Brundage offers an objective, inside look at this emerging technology. His unique perspective translates into an accessible and authoritative guide for readers using XML for documents, Web services, or databases. Key coverage includes: Data model and type system Path navigation Iteration, construction, arithmetic, text processing, type operators and user-defined functions Information beyond the standard—such as a look at update languages, performance benchmarks, query optimization, XQuery style, and much, much more Hundreds of examples The future of XQuery The appendixes provide in-depth information on XQuery's type system, core expressions, built-in functions, regular expressions, and grammar. Meanwhile, the companion Web site offers downloadable source code for all of the examples in the book, the latest on the XQuery standard, answers to readers' questions, XQuery tips and strategies, and more. will show developers, programmers, and database administrators how a single line of this deep and powerful new language can accomplish the equivalent of hundreds of lines written in C, C#, Java, and other general-purpose programming languages.

XPath is to XML as SQL is to databases: XML applications need XPath to locate specific data within an XML document for further processing with other XML applications such as XSLT, XQuery, XPointer, XLink and DOM level 3. With XPath, these applications offer developers a full toolkit for transforming, linking, and searching XML data. Developers need to understand XPath to fully exploit XML in their applications, and they have few resources beyond the W3C specification. XPath Kick Start will examine every aspect of XPath in detail, including its influence on and use with these other XML standards. With each technique illustrated with real-world examples, the book starts with coverage of the essentials of XPath, including nodes, expressions, functions and operators. The second half of the book details XPath in practice - from manipulating XML data to transforming, linking and querying XML documents.

“This book takes the somewhat daunting process of database design and breaks it into completely manageable and understandable components. Mike’s approach whilst simple is completely professional, and I can recommend this book to any novice database designer.” – Sandra Barker, Lecturer, University of South Australia, Australia “Databases are a critical infrastructure technology for information systems and today’s business. Mike Hernandez has written a literate explanation of database technology–a topic that is intricate and often obscure. If you design databases yourself, this book will educate you about pitfalls and show you what to do. If you purchase products that use a database, the book explains the technology so that you can understand what the vendor is doing and assess their products better.” – Michael Blaha, consultant and trainer, author of A Manager’s Guide to Database Technology “If you told me that Mike Hernandez could improve on the first edition of Database Design for Mere Mortals I wouldn’t have believed you, but he did! The second edition is packed with more real-world examples, detailed explanations, and even includes database-design tools on the CD-ROM! This is a must-read for anyone who is even remotely interested in relational database design, from the individual who is called upon occasionally to create a useful tool at work, to the seasoned professional who wants to brush up on the fundamentals. Simply put, if you want to do it right, read this book!” – Matt Greer, Process Control Development, The Dow Chemical Company “Mike’s approach to database design is totally common-sense based, yet he’s adhered to all the rules of good relational database design. I use Mike’s books in my starter database-design class, and I recommend his books to anyone who’s interested in learning how to design databases or how to write SQL queries.” – Michelle Poolet, President, MVDS, Inc. “Slapping together sophisticated applications with poorly designed data will hurt you just as much now as when Mike wrote his first edition, perhaps even more. Whether you’re just getting started developing with data or are a seasoned pro; whether you've read Mike’s previous book or this is your first; whether you're happier letting someone else design your data or you love doing it yourself–this is the book for you. Mike’s ability to explain these concepts in a way that’s not only clear, but fun, continues to amaze me.” –From the Foreword by Ken Getz, MCW Technologies, coauthor ASP.NET Developer's JumpStart “The first edition of Mike Hernandez’s book Database Design for Mere Mortals was one of the few books that survived the cut when I moved my office to smaller quarters. The second edition expands and improves on the original in so many ways. It is not only a good, clear read, but contains a remarkable quantity of clear, concise thinking on a very complex subject. It’s a must for anyone interested in the subject of database design.” – Malcolm C. Rubel, Performance Dynamics Associates “Mike’s excellent guide to relational database design deserves a second edition. His book is an essential tool for fledgling Microsoft Access and other desktop database developers, as well as for client/server pros. I recommend it highly to all my readers.” – Roger Jennings, author of Special Edition Using Access 2002 “There are no silver bullets! Database technology has advanced dramatically, the newest crop of database servers perform operations faster than anyone could have imagined six years ago, but none of these technological advances will help fix a bad database design, or capture data that you forgot to include! Database Design for Mere Mortals™, Second Edition, helps you design your database right in the first place!” – Matt Nunn, Product Manager, SQL Server, Microsoft Corporation “When my brother started his professional career as a developer, I gave him Mike’s book to help him understand database concepts and make real-world application of database technology. When I need a refresher on the finer points of database design, this is the book I pick up. I do not think that there is a better testimony to the value of a book than that it gets used. For this reason I have wholeheartedly recommended to my peers and students that they utilize this book in their day-to-day development tasks.” – Chris Kunicki, Senior Consultant, OfficeZealot.com “Mike has always had an incredible knack for taking the most complex topics, breaking them down, and explaining them so that anyone can ‘get it.’ He has honed and polished his first very, very good edition and made it even better. If you're just starting out building database applications, this book is a must-read cover to cover. Expert designers will find Mike’s approach fresh and enlightening and a source of great material for training others.” – John Viescas, President, Viescas Consulting, Inc., author of Running Microsoft Access 2000 and coauthor of SQL Queries for Mere Mortals “Whether you need to learn about relational database design in general, design a relational database, understand relational database terminology, or learn best practices for implementing a relational database, Database Design for Mere Mortals™, Second Edition, is an indispensable book that you’ll refer to often. With his many years of real-world experience designing relational databases, Michael shows you how to analyze and improve existing databases, implement keys, define table relationships and business rules, and create data views, resulting in data integrity, uniform access to data, and reduced data-entry errors.” – Paul Cornell, Site Editor, MSDN Office Developer Center Sound database design can save hours of development time and ensure functionality and reliability. is a straightforward, platform-independent tutorial on the basic principles of relational database design.
