For me, views often are kind of abstractions or interfaces. Especially when the view contains joins. It hides the details of the data model. Database programmers can even change those details while maintaining the SELECT clause of the view so for the application programmer the interface has not changed.

Hey Ben,

SQL views aren't just stored queries, it's a virtual table. You can make joins and select specific columns, granting permissions to different database users to it, instead of granting permission to every table. Views are also indexed, when talking about materialized views.

So by using SQL views you've got: security, performance and simplicity. Also, not every system is backed by a modern application layer.
