XML has become the lingua franca for representing business data, for exchanging information between business partners and applications, and for adding structure
and sometimes meaning to text-based documents. XML offers some special challenges and opportunities in the area of search: querying XML can produce very precise, fine-grained results, if you know how to express and execute those queries.
For software developers and systems architects: this book teaches the most useful approaches to querying XML documents and repositories. This book will also help managers and project leaders grasp how querying XML fits into the larger context of querying and XML. Querying XML provides a comprehensive background from fundamental concepts (What is XML?) to data models (the Infoset, PSVI, XQuery Data Model), to APIs (querying XML from SQL or Java) and more.
* Presents the concepts clearly, and demonstrates them with illustrations and examples; offers a thorough mastery of the subject area in a single book.
* Provides comprehensive coverage of XML query languages, and the concepts needed to understand them completely (such as the XQuery Data Model).
* Shows how to query XML documents and data using: XPath (the XML Path Language); XQuery, soon to be the new W3C Recommendation for querying XML; XQuery's companion XQueryX; and SQL, featuring the SQL/XML
* Includes an extensive set of XQuery, XPath, SQL, Java, and other examples, with links to downloadable code and data samples."

This book is the best way to make the leap from SQL-92 to SQL: 1999, but it is much more than just a simple bridge between the two. The latest from celebrated SQL experts Jim Melton and Alan Simon, "SQL: 1999" is a comprehensive, eminently practical account of SQL's latest incarnation and a potent distillation of the details required to put it to work. Written to accommodate both novice and experienced SQL users, "SQL: 1999" focuses on the language's capabilities, from the basic to the advanced, and the way that real applications take advantage of them. Throughout, the authors illustrate features and techniques with clear and often entertaining references to their own custom database, which can be downloaded from the companion Web site.

"Advanced SQL:1999 - Understanding Object-Relational and Other Advanced Features" is the practitioner's handbook to the standard's advanced features. It is not a re-presentation of the standard, but rather an authoritative, in-depth guide to its practical application. Like its companion, "SQL:1999 - Understanding Relational Language Components," which explained the standard's basic features, this book will show you how to make your applications both effective and standard-compliant.

This handy reference has a modular format so you can explore specific topics with ease. It is equally useful to those upgrading from earlier versions of SQL and those with no previous experience. Written by the standard's distinguished editor, "Advanced SQL:1999" will complete your knowledge and support your skills like no other book can.
* Focuses entirely on the issues that matter to programmers who are connecting applications to databases.
* Details SQL:1999's object facilities, including structured user-defined types, typed tables, user-defined routines, and routine invocation.
* Examines facilities new to SQL, including those relating to on-line analytical processing (OLAP), management of external data (SQL/MED), and Java support.
* Covers the ongoing development of XML support.
* Includes appendices that cover the SQL:1999 annexes, a SQL:1999 example using UDTs, status codes, and useful information on the standardization process.
