How do you represent VIEWS in an ERD? Are VIEWS (CREATE VIEW) represented in an ERD?   If so, how do you represent them and specify what tables they came from?
There is a view object available in several ERD tools that I've seen (TOAD, Agilian, Visio).  I'm not entirely sure that it is formally a part of any notation, but could be construed as a stereotype, as it is effectively just another entity.

Demonstrating the relationship to the source tables is a bit more difficult, IMO. I would just use a generic connector, especially as the relationship is likely much more complex than can be described visually (I just created a view that is populated in part by functions that run complex queries on multiple tables).  I would absolutely not use the relationship connectors.
