Chapter 20. XML information modeling

Chapter 20. XML information modeling

This chapter addresses some of the general modeling and design questions that come up when designing XML documents, and to a lesser extent the schemas that describe them. For developers who are accustomed to defining data as entity-relationship models, relational tables, UML, and object-oriented models and classes, there is a learning curve associated with the hierarchical model of XML.

This chapter will help you up that curve. It first compares XML modeling and design to other disciplines, such as relational models and object-oriented models, and shows how XML Schema features can be used to describe these models. It then provides some general design principles for modeling web services, dealing with document-oriented narrative content, and working with a hierarchical information model.
