NHibernate can easily map a View as any other Table.
This works as a charm, but it has a problem with Schema Export. Schema Export will detect the view as a table and will attempt to create the unexisting table.
A workaround for this is using <database-object> tag to Drop the unwillable table on creation, someting like:
<database-object>
<create>DROP TABLE UnWantedTable</create>
<drop />
</database-object>
