Finding the Declarative Tipping Point; XQuery, XML, and the RDBMS @ XML JOURNAL

Moving information from a database into an application may be the most common challenge developers face. How many of us make it through life without meeting object/relational (O/R) mapping in some form? Certainly not too many. Lately it has become equally difficult to avoid XML/relational (X/R) mapping. Because XML, and especially XML Schema (XSD), are object-like paradigms, the mapping difficulty is approximately the same. However, under the ever-expanding influence of XML, the extract, transform, load process that gets data from a database into an application (and vice versa) may be about to get radically more simple and declarative.
