Interface oriented programming defines a contract between
two parties - a rule that both stick to and neither care
how the other is providing the functionality. Classic
example would be COM. Object oriented programming is
looking at things behavioraly - in what they do(methods)
and what identifes them(properties). Aspect oriented
programming is new to me. It identifes the aspects of a
program - separates out what's essential(functionality
wise) and what's repetitive(or not so essential from
functionality perspective).
