<div><p>A <dfn class="term">view</dfn> appears like a table to an application
|
||
|
|
program; however, a view contains no data.</p>
|
||
|
|
<p>It is created over one or more tables. A view can contain all the columns
|
||
|
|
of given tables or some subset of them, and can contain all the rows of given
|
||
|
|
tables or some subset of them. The columns can be arranged differently in
|
||
|
|
a view than they are in the tables from which they are taken. A view in SQL
|
||
|
|
is a special form of a nonkeyed logical file.</p>
