Ok, lets fix this confusion once and for all Dawn. This one /cannot/
go wrong. I have every faith that this coming analogy will clear
things up. No siree. Cannot fail.
- Ok, consider a Declarative programming language. Say lisp (or
Haskell, etc):
- Obviously noone would say such a language is procedural - it just
declares... and thats it.
- /However/ if one had a system was configured such that given some
user input, a different lisp program was fired up... well would that
mean that lisp was now procedural? Of course not.
- Thats how clear the separation in layers is.
Its clear the 'navigation' began before the lisp program started. Its
the exact same pattern when we query databases declaratively -
navigation just doesn't happen, never, not a sausage at the logical
layer. In theory.
