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.
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.
XML, the Extensible Markup Language, is everywhere: the syntax of choice for newly designed document formats across almost all computer applications. Now used daily by developers, XML is living up to its reputation as one of the most important developments in document interchange in the history of computing. A perennial bestseller, the handy XML Pocket Reference from O'Reilly has been revised once again to give you quick access to the latest goods. In addition to its comprehensive look at XML, this third edition has been updated with new material on Namespaces and XML Schema--considered among the most important elements in current XML use--along with RELAX NG and Schematron, additional powerful tools for describing XML document structures. Like other titles in O'Reilly's Pocket Reference series, the XML Pocket Reference, 3rd Edition features a well-organized format that gets right to the point. As a result, it's already won over the allegiance of developers everywhere. If you need XML answers quick and on the fly, this compact book is most definitely the book for you.
& Critical rules of thumb employed by the experts - the things they almost always do or almost always avoid doing - to get the most out of XML. & & Drawing on years of experience, Harold explains 50 ways to use XML to produce code that is extensible, legible, and maintainable. & & The latest addition to Scott Meyers' Effective Software Development Series.
With both an introduction to creating schemas and a guide to the many complexities of the XML Schema Recommendation, this handbook is an on-the-fly learning aid for a tough subject.
"The book addresses a sorely missing set of considerations in the real world... This is a very timely book."-Peter Herzum, author of Business Component Factory and CEO of Herzum SoftwareXML is a tremendous enabler for platform agnostic data and metadata exchanges. However, there are no clear processes and techniques specifically focused on the engineering of XML structures to support reuse and integration simplicity, which are of particular importance in the age of application integration and Web services. This book describes the challenges of using XML in a manner that promotes simplification of integration, and a high degree of schema reuse. It also describes the syntactical capabilities of XML and XML Schemas, and the similarities (and in some cases limitations) of XML DTDs. This book presents combinations of architectural and design approaches to using XML as well as numerous syntactical and working examples.* Designed to be read three different ways: skim the margin notes for quick information, or use tables in the appendix to locate sections relevant the to a particular issue, or read cover-to-cover for the in-depth treatment. * Contains numerous tables that describe datatypes supported by the most common DBMSs and map to XML Schema supported data types.* Unique focus on the value added role and processes of the data architect as they apply to enterprise use of XML.
