Abstract:

This chapter explores the various methods for mapping between XML and relational data models. It focuses on the underlying fundamentals: goals and requirements for mapping between XML and relational data; issues that arise when mapping, such as handling of datatypes and order; and when a particular technique can or cannot support update operations.
