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: In addition to the explanatory content, 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 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.

Developing applications for the enterprise introduces challenges quite different from those associated with developing applications for desktops or small departments. This book offers a no-nonsense approach to enterprise development using Access 2002 as a front-end. it is written in a practical style and easily transitions the client/server neophyte to the sophisticated world of enterprise development. Although the book focuses on client/server development, the text covers other enterprise topics such as replication, trasaction processing, and data access pages. This book goes behond the basics covered by the many introductory books, but offers an easier read than the expert books available.

Constant, continuing, and cataclysmic change is causing a major crisis within business organizations today. Faced with constantly advancing technology, unpredictable market shifts, intense global competition, and an increasingly independent "free agent" workforce, the only way for an organization to adapt and succeed is to build a "culture of inclusion" that nurtures and draws on the talents of a diverse workforce. Easy to say but hard to do; most organizations are mired in industrial revolution, static-world business models administered by monocultural, bordering-on-oppressive, "command and control" hierarchies. Organizations at risk include Fortune 500 giants, entrepreneurial start-ups, manufacturing and retail operations, government agencies, not-for-profits, educational institutions, and others. Most organizational change efforts-whether labeled as diversity efforts, re-engineering, right-sizing, or total-quality-management-are a waste of time, money, and human effort. Most produce more cynicism than results, and they can poison the waters for future change efforts. The Inclusion Breakthrough cuts a path through this potential minefield, offering a proven methodology for strategic organizational change, including models for diagnosing, planning, and implementing inclusion-focused, culture-change strategies tailored to each organization's individual needs. It also describes the key competencies for leading and sustaining a culture of inclusion. Offering real-world results of "before and after" surveys, including anecdotal and statistical reports of organizational change achieved using the methodologies described, The Inclusion Breakthrough presents an overview of current workplace conditions, attitudes, and policies based on interviews, surveys, and focus groups encompassing thousands of people in major organizations. The Inclusion Breakthrough demonstrates why the bottom line must be the central focus of any change strategy-and more importantly, how to carry that strategy out successfully.

Tuning your database for optimal performance means more than following a few short steps in a vendor-specific guide.

Sams¿ PHP and MySQL Web Development, by Luke Welling and Laura Thomson, showed that there is a strong demand for books that describe how to use PHP together with a specific open-source database to develop Web applications. While MySQL is very popular, PostgreSQL is widely considered to be the more powerful of the two open-source databases. And PostgreSQL is rapidly gaining market share large organizations are beginning to use PostgreSQL instead of Oracle; the demand for PostgreSQL training and support has increased by some accounts 50% in the last six months; and Web hosting services increasingly offer PostgreSQL along with MySQL. PHP and PostgreSQL Advanced Web Programming focuses on the specific needs of a PostgreSQL developer and will detail how to make use of PostgreSQL¿s unique, advanced features to develop high-availability, fail-safe Web applications with PHP and PostgreSQL.

MySQL is the most popular SQL database in the open source community and is used almost universally by web sites running on open source systems. As powerful and flexible as it is lightweight and efficient, MySQL packs a large feature set into a very small and fast engine that now runs on more than 500,000 servers. This renowned online manual that has supported MySQL administrators and database developers for years is now available in paperback format. This book is an exact reproduction of the MySQL Reference Manual from the MySQL development team's Web site, minus some non-technical appendices. This version covers MySQL 4.0. Many sophisticated topics appear in this comprehensive manual, ranging from the hitches you may run into when first installing MySQL to internals that will help you tune your queries. MySQL Reference Manual contains all the comprehensive reference material one would expect for building the product, running administrative utilities, and using various API as well as MySQL's rich version of SQL. In addition, you can turn a page and find such unexpected riches as: A thorough comparison of MySQL with SQL standards and other databases A discussion of privileges and suggested uses of privileges to enhance security Directions for replicating a database and for running several MySQL servers on a single system Directions for initializing a database from a flat file Guidelines for estimating the performance of different queries A far-reaching discussion of optimization, with reference to the implementation of MySQL Investigations of the differences between data types and the pros and cons of each type of number, string, or timestamp An extended inquiry into the effects of using delayed inserts A candid explanation of why various errors occur and how to recover from them Tips for weighted, full-text searches Detailed descriptions of the features, strengths, and weaknesses of available table formats A guide to adding new functions to MySQL No serious MySQL user should be without this book.

More Java developers today want to work with XML, the technology that enables data to be transported intact over the Internet, but they don't have time to become XML experts. If this describes you, then you'll appreciate data binding, the new way of converting XML documents into Java objects, so those documents can be worked on and manipulated like any other Java object, then converted back to XML This new title provides an in-depth technical look at XML Data Binding. The book offers complete documentation of all features in both the Sun Microsystems JAXB API and popular open source alternative implementations (Enhydra Zeus, Exolabs Castor and Quick). It also gets into significant detail about when data binding is appropriate to use, and provides numerous practical examples of using data binding in applications. As Author Brett McLaughlin says "Too many books are written about technologies by people who barely understand them. I've already written two data binding implementations (Zeus, and a previous one for IBM DeveloperWorks.) I've actually used data binding for longer than the official specification has been in existence, and I've really been able to dig into what it takes to code an effective data biding implementation, as well as use one correctly. This book is part user guide, part under-the-hood manual, and part use-case. It's a powerful combination, and one I think people need."

Web services enable the new generation of Internet-based applications. These services support application-to-application Internet communication--that is, applications at different network locations can be integrated to function as if they were part of a single, large software system. Examples of applications made possible by Web services include automated business transactions and direct (nonbrowser) desktop and handheld device access to reservations, stock trading, and order-tracking systems. Several key standards have emerged that together form the foundation for Web services: XML (Extensible Markup Language), WSDL (Web Services Definition Language), SOAP (Simple Object Access Protocol), and UDDI (Universal Description, Discovery, and Integration). In addition, ebXML (Electronic Business XML) has been specified to facilitate automated business process integration among trading partners. This book introduces the main ideas and concepts behind core and extended Web services' technologies and provides developers with a primer for each of the major technologies that have emerged in this space. In addition, summarizes the major architectural approaches to Web services, examines the role of Web services within the .NET and J2EE communities, and provides information about major product offerings from BEA, Hewlett-Packard, IBM, IONA, Microsoft, Oracle, Sun Microsystems, and others. Understanding Web Services Key topics include: XML facilities for structuring and serializing data How WSDL maps services onto communication protocols and transports WSDL support for RPC-oriented and document-oriented interactions SOAP's required and optional elements Message processing and the role of intermediaries in SOAP UDDI data formats and APIs How ebXML offers an alternative to Web services that supports reliable messaging, security, and trading-partner negotiations With , you will be well informed and well positioned to participate in this vast, emerging marketplace.

Today MQSeries offers the programmer more choices than ever in which to write new MQSeries applications, from the most traditional Message Queue Interface API all the way through to the popular and highly portable JMS interface. Because of the many options available, it can sometimes be difficult for an application programmer new to MQSeries to easily understand the differences and benefits of each, or appreciate the implications of using one programming approach versus another. This redbook will help you install, tailor and configure specialist tools such as JMS admin, and will help you to design/create MQSeries applications. It gives a broad and general understanding of the currently available MQSeries APIs. We do this first by describing some of the more common examples and coding patterns, and then explaining each one in turn using the different APIs MQSeries supports to show the merits of each particular programming choice. This redbook positions the different MQSeries programming choices against each other in such a way as to help the application writer to make a clearer and more informed judgment as to which is the most suitable programming method for a particular situation.

What do eBay, Amazon.com and CNN.com have in common? They're all applications that integrate large databases with the Web. The popularity (and power) of these applications stems from their accessibility and usability: thousands of users can access the same data at the same time without theneed to install any additional software on their computers. Web Database Applications with PHP and MySQL offers web developers a mixture of theoretical and practical information on creating web database applications. Using PHP, and MySQL, two open source technologies that are often combined to develop web applications, the book offers detailed information on designing relational databases and on web application architecture, both of which will be useful to readers who have never dealt with these issues before. The book also introduces Hugh and Dave's Online Wines, a complete (but fictional) online retail site that allows users to browse, search a database, add items to a shopping cart, manage their membership, and purchase wines. Using this site as an example, the book shows you how to implement searching and browsing, store user data, validate user input, manage transactions, and maintain security. If you want to build small to medium-scale web database applications that can run on modest hardware and process more than a million hits a day from users, this book will show you how.
