Answer to Question 2
A dynamic view is useful, since it provides a way to access part of a table or a combination of columns from multiple tables. A view can simplify query commands, since much of the complicated syntax of a query can be done to create the view. A view can also improve programmer productivity, since programmers can access views rather than have to rewrite the SQL commands for a query. Security is increased, since users can only see what the view presents. Also, views use little or no storage space. On the downside, views use processing time each time that the view is recreated for reference. Also, the views may or may not be recreatable.
