10. The term named program unit indicates that the program is saved in a database and, therefore, can be
used or shared by different applications.
ANS: F PTS: 1 REF: 6
11. An event can range from a user action, such as clicking the button on the screen, to a table update
statement that autоmatically calls a database trigger.
, ANS: T PTS: 1 REF: 8
