 * SQL can apply functions to values from tables. Examples of
 * such functions are MIN(a1,a2) or SQRT(num). Many functions are
 * implemented in SQL engine.
 *
 * This interface allows consumers to implement their own,
 * problem-specific functions.
 * These functions can be called from triggers, too.
