+### Description
+Views are based on the result-set of an `SQL` query. `CREATE VIEW` constructs
+a virtual table that has no physical data therefore other operations like
+`ALTER VIEW` and `DROP VIEW` only change metadata. 
+
+### Syntax
+{% highlight sql %}
+CREATE [OR REPLACE] [[GLOBAL] TEMPORARY] VIEW [IF NOT EXISTS] [db_name.]view_name
+    create_view_clauses
+    AS query;
+{% endhighlight %}
+
+### Parameters
+<dl>
+  <dt><code><em>OR REPLACE</em></code></dt>
+  <dd>If a view of same name already exists, it will be replaced.</dd>
+</dl>
+<dl>
+  <dt><code><em>[GLOBAL] TEMPORARY</em></code></dt>
+  <dd>TEMPORARY views are session-scoped and will be dropped when session ends 
+      because it skips persisting the definition in the underlying metastore, if any.
+      GLOBAL TEMPORARY views are tied to a system preserved temporary database `global_temp`.</dd>
+</dl>
+<dl>
+  <dt><code><em>IF NOT EXISTS</em></code></dt>
+  <dd>Creates a view if it does not exists.</dd>
+</dl>
+<dl>
+  <dt><code><em>create_view_clauses</em></code></dt>
+  <dd>These clauses are optional and order insensitive. It can be of following formats.
+    <ul>
+      <li><code>[(column_name [COMMENT column_comment], ...) ]</code> to specify column-level comments.</li>
+      <li><code>[COMMENT view_comment]</code> to specify view-level comments.</li>
+      <li><code>[TBLPROPERTIES (property_name = property_value, ...)]</code> to add metadata key-value pairs.</li>
+    </ul>  
+  </dd>
+</dl>
+<dl>
+  <dt><code><em>query</em></code></dt>
+  <dd>A <a href="sql-ref-syntax-qry-select.md">SELECT</a> statement that constructs the view from base tables or other views.</dd>
+</dl>

+-- Create or replace view for `experienced_employee` with comments.
+CREATE OR REPLACE VIEW experienced_employee
+    (ID COMMENT 'Unique identification number', Name) 
+    COMMENT 'View for experienced employees'
+    AS SELECT id, name FROM all_employee
+        WHERE working_years > 5;
+
+-- Create a global temporary view `subscribed_movies` if it does not exist.
+CREATE GLOBAL TEMPORARY VIEW IF NOT EXISTS subscribed_movies 
+    AS SELECT mo.member_id, mb.full_name, mo.movie_title
+        FROM movies AS mo INNER JOIN members AS mb 
+        ON mo.member_id = mb.id;
