Product Description
Web Services are self-describing, modular applications. The Web Services architecture can be thought of as a wrapper for the application code. This wrapper provides standardized means of: describing the Web Service and what it does; publishing it to a registry, so that it can easily be located; and exposing an interface, so that the service can be invoked – all in a machine-readable format. What is particularly compelling about Web Services is that they can be accessed by any client that understands XML, regardless of the platform, language, or object model.
This book provides a snapshot of the current state of these rapidly evolving technologies, beginning by detailing the main protocols that underpin the Web Services model (SOAP, WSDL, and UDDI), and then putting this theory to practical use in a wide array of popular toolkits, platforms, and development environments.
The technologies presented in this book provide the foundations of Web Services computing, which is set to revolutionize Distributed Computing, as we know it.

Whatever your favorite programming language, Professional XML Web Services does a good job at explaining recent technologies and tools needed to understand and use Web services. Whether you are a developer or an IT manager, this book’s wide-ranging perspective on some late-breaking standards and tools will help you design and code the next generation of Web applications.
The strong cross-language perspective is what distinguishes this title from the rest of the pack. The book surveys actual tools for developing Web services in C++, Java, Perl, Python, and Microsoft’s new C# language (part of .NET). Short chapters survey what’s out there for Web services developers, with options from IBM, Sun, HP, and Microsoft. If you are somehow convinced that one vendor has a head start with Web services, you’ll think again after reading this volume.
The heart of this text is its thorough and approachable tour of core standards needed for Web services, from the innards of SOAP for sending messages between systems over HTTP or other protocols, to WSDL for describing Web services and UDDI for looking them up at run-time. The book does a good job at fixing a very fast moving target. (SOAP 1.1 is used here instead of the emerging 1.2 standard.) Besides the new .NET (and ADO.NET) on the Microsoft platform, there’s also coverage of the older SOAP Toolkit 2.0. Sections on using Perl and Python will help bring fans of these popular Web development languages onboard with Web services.
The authors conclude with two larger case studies, an interesting remote file system exposed through Web services using Java, plus an auction database done in the new C#. Anchoring the discussion in what are sure to be the two most popular choices for Web services development helps ensure this text has a practical focus, too. With its range of coverage of what Web services are and the actual standards and tools used to implement them, this title is a perfect choice for learning what all the fuss is about. It’s all anyone needs to start designing and coding with Web services using many of today’s most popular programming languages and tools. –Richard Dragan
Professional SQL Server 2000 XML
Product Description
The most important new features of SQL Server 2000 concern XML and the added functionality that it provides. This includes the ability to use XML documents to update your database, access SQL Server through HTTP and retrieve data from your database in XML format.
Building extensively on the new features introduced in Professional SQL Server 2000 (1-861004-48-6) this book goes beyond just the key issues and provides blanket in-depth coverage of advanced topics, including both XDR and XSD schemas (support for which has been added in the new Web Release 2), and additions in Web Release 1, such as Updategrams and XML Bulk Load. This book also includes five real-world case studies that show exactly how the XML capabilities of SQL Server 2000 can best be exploited with technologies as diverse as ASP, C#, and SOAP.
This book covers:
An introduction to XML
How to retrieve XML data from your database using FOR XML
Exposing XML documents as relational resultsets using OPENXML
Using XDR and XSD schemas to retrieve results through HTTP requests
Describing SQL Server tables using XML Views
A detailed discussion of the use of XPath queries with SQL Server
Modifying your database with Updategrams
Importing XML documents into your database with XML Bulk Load
An overview of the new features provided with Beta 1 of Web Release 2
Amazon.com Review
Key to the interoperability of Microsoft SQL Server 2000–its ability to exchange information with other database management systems and with client applications–is its support of Extensible Markup Language (XML). Regardless of whether you’re a database administrator charged with designing and maintaining databases or a software developer who uses SQL Server at the back end of a multitiered application, you need to understand what XML is all about, and how SQL Server goes about reading and writing it. Professional SQL Server 2000 XML uses an approach typical of Wrox Press–liberal commentary interspersed with plenty of examples that build on one another–to help its readers learn about its subject.
This book was written by a team of authors, each of whom wrote a few chapters in his or her specialty area. Like any book written by several people, this one displays different writing styles throughout, but the effect is not striking if you use the book mainly as a reference. Each author typically takes on the capabilities of SQL Server and XML one at a time, explaining what each is all about before launching into examples (complete with code) that reveal the mechanisms at work. It’s a lot of information to absorb, but the authors do a fine job of presenting it logically. Case studies present big projects that each employ several of SQL Server’s XML capabilities. –David Wall
Topics covered: The XML capabilities of Microsoft SQL Server 2000, including the FOR XML clauses in Transact-SQL, the OpenXML specification, XDR and XSD schemas, templates, views, and updategrams.
