An application environment is partitioned into channels (C)
and tiers (T).
o Channels are used for partitioning user-groups
o Tiers are used for layering the application
Channels and tiers span an environment into a two-dimensional
space of domains: D = C x T.

t0 t1 ... tn

c0 c0-t0 c0-t1 ... c0-tn

c1 c1-t0 c1-t1 ... c1-tn

c2 c2-t0 c2-t1 ... c2-tn

... ... ... ... ...

cn cn-t0 cn-t1 ... cn-tn

Example:
C = {b2c, b2e}
T = {presentation, frontlogic, dataprovider}

The set of domains D = C x T is then as follows:
D = {
b2c-p, b2c-f, b2c-dp, b2e-p, b2e-f, b2e-dp}.

To be more general, the domains of an application
environment can be defined as follows:

D = Union(Ci x Ti).

Example:
C0 = {c0 = b2c, c1 = b2e}
T0 = {presentation, frontlogic}

D = {b2c-p, b2c-f, b2e-p, b2e-f}
