+ * 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.
