Description:
Most XML books focus on the XML language and its related dialects: XSL, Xlink, and Xpointer. XML for Real Programmers delivers something different--a combination of an XML tutorial and an ambitious exploration of Java implementations of XML. The first section focuses on XML specifications and includes some excellent examinations of the core concepts, plus hypothetical examples of how XML can be leveraged in the real world. For example, the text introduces a scenario where XML is used as a data-transfer standard between various suppliers and a corporate Enterprise Resource Planning (ERP) system. The book also illustrates how XML can be used effectively in the order-processing stage of a typical business-to-consumer e-commerce site. With many other examples, the first portion of this book is great for anyone looking to get the "big picture" of what XML is all about. After the XML overview section, the subject matter rapidly becomes more challenging. The book begins a case study that lasts throughout the remainder of the title. To follow this section effectively, Java expertise is required. The case study lacks the clear architectural diagrams used so frequently in the first half of the book, so the reader must pay closer attention. The book presents a Java servlet that interfaces with a database via JDBC, and dishes up XML to other objects and browser clients. The text shows how to construct a generic XML DOM interface and create classes for an e-commerce account system, catalog, and shopping basket. The model continues with back-end integration with distributors via XML. Although Java proficiency is a prerequisite for complete understanding of this book, the first section can be quite useful for developers in any language, as well as technical managers seeking clarity about the importance of XML. In this book, working Java programmers will find an XML tutorial that is finally targeted at their tribe. --Stephen W.
