XML in Data Management is for IT managers and technical staff involved in the creation, administration, or maintenance of a data management infrastructure that includes XML. For most IT staff, XML is either just a buzzword that is ignored or a silver bullet to be used in every nook and cranny of their organization. The truth is in between the two. This book provides the guidance necessary for data managers to make measured decisions about XML within their organizations. Readers will understand the uses of XML, its component architecture, its strategic implications, and how these apply to data management.


* Takes a data-centric view of XML.
* Explains how, when, and why to apply XML to data management systems.
* Covers XML component architecture, data engineering, frameworks, metadata, legacy systems, and more.
* Discusses the various strengths and weaknesses of XML technologies in the context of organizational data management and integration.

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.

XForms Essentials is an introduction and practical guide to the new XForms specification. Written by Micah Dubinko, a member of the W3C XForms working group and an editor of the specification, the book explains the how and why of XForms, showing readers how to take advantage of them without having to write their own code. You'll learn how to integrate XForms with both HTML and XML vocabularies, and how XForms can simplify the connection between client-based user input and server-based processing. If you work with forms, HTML, or XML information, XForms Essentials will provide you with a much simpler route to more sophisticated interactions with users.

HTML is changing so fast it's almost impossible to keep up with developments. XHTML is HTML 4.0 rewritten in XML; it provides the precision of XML while retaining the flexibility of HTML. HTML & XHTML: The Definitive Guide, 4th Edition, brings it all together. It's the most comprehensive book available on HTML and XHTML today. It covers Netscape Navigator 6.0, Internet Explorer 5.0, HTML 4.01, XHTML 1.0, JavaScript, Style sheets, Layers, and all of the features supported by the popular web browsers.

Learning HTML and XHTML is like learning any new language, computer or human. Most students first immerse themselves in examples. Studying others is a natural way to learn, making learning easy and fun. Imitation can take learning only so far, though. It's as easy to learn bad habits through imitation as it is to acquire good ones. The better way to become HTML-fluent is through a comprehensive reference that covers the language syntax, semantics, and variations in detail and demonstrates the difference between good and bad usage.

XML is buried everywhere in the Microsoft .NET Framework, but effective XML parsing and coding in .NET requires adjustment. This book describes the set of XML core classes in .NET, introduces the .NET XML parsing model and how to program against it, and discusses XML readers and writers and XMLDOM. It examines related technologies such as schemas, transformations, and XPath, and it discusses data issues such as synchronization and serialization, the DiffGram format, and the XML extensions in Microsoft SQL Server 2000. This Microsoft Press title also reveals how to get the best performance from XML with .NET, and it offers in-depth information on interoperability topics such as when to use XML Web services and when to use remoting.
