What is XML-to-Relational Mapping

Handbook of Research on Innovations in Database Technologies and Applications: Current and Future Trends
A method which specifies how XML data are stored into relations of a relational database management system. It involves a definition of the target database schema and a way how the data are stored into its relations. Related problems are data retrieval and data updates, but they are usually determined directly by the storage strategy.

Abstract
Without any doubt, the eXtensible Markup Language (XML) (Bray et al., 2006) is currently one of the most popular formats for data representation. Its wide popularity naturally invoked an enormous endeavour to propose faster and more efficient methods and tools for managing and processing of XML data. Soon it was possible to distinguish several different directions. The four most popular ones are methods which store XML data in a classical file system, methods which store and process XML data using a relational database management system, methods which exploit a pure object-oriented approach and native methods that use special indices, numbering schemas and/or data structures proposed or suitable particularly for tree structure of XML data.
