See how you can use pureQuery -- IBM's new paradigm for writing Java™ database applications.

Three scenarios are described in this demo. The first one is database-driven objectization, or relational table-to-Java transformation. The second is query-driven objectization, or SQL-to-Java transformation.
The third is object-relational mapping, or Java-to-SQL transformation.
