The document discusses several Java technologies presented at the JJUG CCC 2010 Fall conference, including XML SmartDoc, Relaxer, SimpleModeler, and g3. It focuses on g3, a framework built using Scala that utilizes DSLs and supports REST/Atom, event-driven architectures, and integration patterns like splitter/aggregator. Key-value stores and CQRS are presented as alternatives to relational databases for building scalable applications.
