I've looked at a few sites now, and I'm still struggling to find a complete listing of all the possible layers/tiers you can have in an application.

From back in college (1999) I remember the following:

Presentation Layer (Views)
Application Layer (Controllers)
Business Logic Layer (API/Rules)
Persistence Layer (Database/Object Persistence/Model)

I'm not advocating that they all be used...especially when you consider that too many layers/tiers could lead to an increase in complexity...I just wondered what the complete list might look like...

Based on a couple of blogs I've found several different answers...and Javascript and client side technologies seem to have leaked in adding more client-side layers according to one blog the client side tier might even consist of

Behavior Layer (Javascript, Flash)
Presentation Layer (CSS/Images) Note: I though the entire client side layer was the presentation layer
Structure Layer (XHTML, HTML)

I'm just trying to get an abstract idea of what all the possible layers might be, (even though some people call them different things)
