A view itself has an underlying query. I have seen too much code, based on joins of views leading to, eerrr, sub-optimal performance.
Rule #7 of some Basic Performance Tips document stated not to
code joins over views, but use the underlying statement, or
create a new view.
The modification is mine: there's no join here.
