<div><p>A view can prevent unauthorized users from having access to sensitive
|

data.</p>
|
|
<div class="section"><p>The application program can access the data it needs
|
|
in a table, without having access to sensitive or restricted data in the table.
|
|
A view can restrict access to particular columns by not specifying those columns
|
|
in the SELECT list (for example, employee salaries). A view can also restrict
|
|
access to particular rows in a table by specifying a WHERE clause (for example,
|
|
allowing access only to the rows associated with a particular department number).</p>
