A thing about views, that nobody else seem to have mentioned is that the view text is not stored in the dictionary cache. Hence, each time you hard parse a sql statement with a view, Oracle will query view$ to get the text. Hence, if you are at the limit of scalability or performance due to hard parses, views make things worse.
