"The whole world is talking XML, and the ramifications of its universal adoption are only beginning to surface. Whole business models will be affected by it; whole new business interests are being pursued because of it. The software industry itself will be rocked by it more than it cares to admit. This is so because XML brings us into the promised land of componentware."From the foreword by Dr. Peter Mossack, VP, Software AG.
"System Architecture with XML covers today's most important issues in XML specifications and technology. It is a "must read" for architects who need to integrate XML into their enterprise systems."Tom Marrs, Senior J2EE/XML Architect, Distributed Computing Solutions, Inc.
XML is bringing together some fairly disparate groups into a new cultural clash: document developers trying to understand what a transaction is, database analysts getting upset because the relational model doesn't fit anymore, and web designers having to deal with schemata and rule based transformations. The key to rising above the confusion is to understand the different semantic structures that lie beneath the standards of XML, and how to model the semantics to achieve the goals of the organization.
A pure architecture of XML doesn't exist yet, and it may never exist as the underlying technologies are so diverse. Still, the key to understanding how to build the new web infrastructure for electronic business lies in understanding the landscape of these new standards.
If your background is in document processing, this book will show how you can use conceptual modeling to model business scenarios consisting of business objects, relationships, processes, and transactions in a document-centric way. Database designers will learn if XML is subject to relational normalization and how this fits in with the hierarchical structure of XML documents. Web designers will discover that XML puts them into a position to automatically generate visually pleasing web pages and rich multimedia shows from otherwise dry product catalogues by using XSLT and other transformation tools. Business architects will see how XML can help them to define applications that can be quickly adapted the ever changing requirements of the market.
