 * at the end of any statement or transaction that modifies one or more of the tables that the notifier is listening to.
 * In other words, it functions as a simple listener that can execute arbitrary code after any change to a table.
 * <p>
 * Note: Be wary of making further database changes from within onDataChanged()! It could trigger recursive data change
 * notifications, which could eventually lead to a StackOverflowException or an infinite loop.
