Re: Tier?

Physical separation of components does not dictate the number of tiers.
DNA is broken down into 3 logical tiers - presentation, business and
data access. N-tier is when we describe DNA models that contain proxy
layers to cater for cross process communication complexities.
To know how many tiers you have look at what your code does, rather than
where it is placed.

I'm not sure what the (EXE) application does, but it's sure going to be
a bottleneck in your system!
