Aspect Oriented Programming (AOP) vs OOP

Aspect Oriented Programming:

Prior to study of AOP you must understand few terminologies in terms of programming .

1. Aspect
2. concern
3. core concern
4. cross cutting concern  

Description:

Aspect:

Concern:

Core Concern:

Cross Cutting Concern:

Now what is AOP?

• It is specialized programming methodology using which "cross cutting concern" is dynamically decoupled from "core concern" 
• The key unit of modularity in AOP is the aspect. Aspects enable the modularization of concerns such as transaction management that cut across multiple types and objects. 
• AOP is not replacement for OOP
• core concern is modularized using OOP whereas crosscutting concern is modularized using AOP.
