This reference provides detailed examples of every XML schema component, its corresponding schema document element, and all of the associated attributes. The mapping of an XML schema to a relational SQL schema is covered with examples written for Oracle9i. The final chapter is a case study of a campus resource and scheduling system that uses SQL 2000, the .NET framework, XDR schemas, IIS, and Visual Basic.

If you need to create or use formal descriptions of XML vocabularies, the W3C's XML Schema offers a powerful set of tools for defining acceptable document structures and content. An alternative to DTDs as the way to describe and validate data in an XML environment, XML Schema enables developers to create precise descriptions with a richer set of datatypes?such as booleans, numbers, currencies, dates and times?that are essential for today?s applications.Schemas are powerful, but that power comes with substantial complexity. This concise book explains the ins and outs of XML Schema, including design choices, best practices, and limitations. Particularly valuable are discussions of how the type structures fit with existing database and object-oriented program contexts. With XML Schema, you can define acceptable content models and annotate those models with additional type information, making them more readily bound to programs and objects. Schemas combine the easy interchange of text-based XML with the more stringent requirements of data exchange, and make it easier to validate documents based on namespaces.You?ll find plenty of examples in this book that demonstrate the details necessary for precise vocabulary definitions. Topics include: Foundations of XML Schema syntax Flat, "russian-doll", and other schema approaches Working with simple and complex types in a variety of contexts The built-in datatypes provided by XML Schema Using facets to extend datatypes, including regular expression-based patterns Using keys and uniqueness rules to limit how and where information may appear Creating extensible schemas and managing extensibility Documenting schemas and extending XML Schema capabilities through annotations In addition to the explanatory content, XML Schemaprovides a complete reference to all parts of both the XML Schema Structures and XML Schema Datatypes specifications, as well as a glossary. Appendices explore the relationships between XML Schema and other tools for describing document structures, including DTDs, RELAX NG, and Schematron, as well as work in progress at the W3C to more tightly integrate XML Schema with existing specifications.No matter how you intend to use XML Schema - for data structures or document structures, for standalone documents or part of SOAP transactions, for documentation, validation, or data binding ? all the foundations you need are outlined in XML Schema.

“XML Schema 1.1 has gone from strong data typing to positively stalwart—so powerful it can enforce database level constraints and business rules, so your data transfer code won’t have to. This book covers the 1.1 changes—and more—in its 500 revisions to Priscilla Walmsley’s 10-year best-selling classic. It’s the guide you need to navigate XML Schema’s complexity—and master its power!” —Charles F. Goldfarb For Ten Years the World’s Favorite Guide to XML Schema—Now Extensively Revised for Version 1.1 and Today’s Best Practices! To leverage XML’s full power, organizations need shared vocabularies based on XML Schema. For a full decade, Definitive XML Schema has been the most practical, accessible, and usable guide to working with XML Schema. Now, author Priscilla Walmsley has thoroughly updated her classic to fully reflect XML Schema 1.1, and to present new best practices for designing successful schemas. Priscilla helped create XML Schema as a member of the W3C XML Schema Working Group, so she is well qualified to explain the W3C recommendation with insight and clarity. Her book teaches practical techniques for writing schemas to support any application, including many new use cases. You’ll discover how XML Schema 1.1 provides a rigorous, complete specification for modeling XML document structure, content, and datatypes; and walk through the many aspects of designing and applying schemas, including composition, instance validation, documentation, and namespaces. Then, building on the fundamentals, Priscilla introduces powerful advanced techniques ranging from type derivation to identity constraints. This edition’s extensive new coverage includes Many new design hints, tips, and tricks – plus a full chapter on creating an enterprise strategy for schema development and maintenance Design considerations in creating schemas for relational and object-oriented models, narrative content, and Web services An all-new chapter on assertions Coverage of new 1.1 features, including overrides, conditional type assignment, open content and more Modernized rules for naming and design Substantially updated coverage of extensibility, reuse, and versioning And much more If you’re an XML developer, architect, or content specialist, with this Second Edition you can join the tens of thousands who rely on Definitive XML Schema for practical insights, deeper understanding, and solutions that work.

The art of writing XML schema in a systematic way.

This reference for programmers and web developers covers all of XML along with related protocols and technologies. It is assumed that the reader has a basic understanding of XML. The authors are both with DevelopMentor's technical staff. c. Book News Inc.

This single-source reference and tutorial brings together up-to-the-minute information about every key XML technology. The book's unique features are designed to make XML easier than ever to master and use effectively. Throughout, Kenneth B. Sall provides two parallel sets of examples: "QuickTrack" examples for beginners and those seeking a quick overview of how the technology works, and "Advanced Track" examples for readers who want to drill down for a more sophisticated understanding. The book includes extensive tables designed for rapid access to key information, plus as a "Big Picture Map" showing how virtually every key W3C XML-related initiative fits together.KEY TOPICS:Sall begins by reviewing XML's history, goals, evolution, fundamental concepts, and syntax. He covers parsing and programming APIs, techniques for displaying and transforming XML, related core XML specifications, and specialized XML vocabularies. Among the XML-related technologies covered in this book: XSL, DOM, P3P, CSS, Xlink, and Xpointer. The book includes a full chapter on XSLT by G. Ken Holman, current chair of the OASIS XSLT Conformance Technical Subcommittee; and a full chapter on the Resource Definition Framework (RDF) by Oral Lassila, a member of the W3C working group on RDF.MARKET:For every Web professional and software developer working with XML.

The Complete Reference to Professional SOA with Visual Studio 2005 (C# & VB 2005) focuses on architecting and constructing enterprise-level systems. Taking advantage of the newly released Visual Studio 2005 development environment, the book assesses the current service-oriented platform and examines new ways to develop for scalability, availability, and security (which have become available with .NET 2.0). You'll get to look closely at application infrastructure in terms of flexibility, interoperability, and integration, as well as the decisions that have to be made to achieve optimum balance within your architecture.
