The solution does not lend itsself to being distributed acrossload tolerant physicalarchitecture. The separation of concernsbecomes blurred between thelayers making it hard andexpensive to maintain code. Data has a tendency to beleaked across the solution up tothe UI making many N-Tiersystems very vulnerable toexploits such as Sql InjectionAttacks. N-Tier models tend to result inteams that have tier focuseddevelopers who are not crossskilled across layers.
