 * Typically, a <code>JoinRowSet implementation is leveraged by
 * <code>RowSet instances that are in a disconnected environment and
 * thus do not have the luxury of an open connection to the data source to
 * establish logical relationships between themselves. In other words, it is
 * largely <code>CachedRowSet objects and implementations derived from
 * the <code>CachedRowSet interface that will use the JoinRowSetImpl
 * implementation.
