In-Depth Information
•
Data modification (insert, update, and delete operations) can be
applied through views in the normal (SQL) manner, providing
that the view is updateable (more on this later). The view
statements are compiled or translated (depending on the DBMS),
and the implied base relations are updated at execution time.
•
Views can also be queried in a manner that is identical to how
base relations are queried.
