Editor?s Choice -AOP and IoC

AOP-New Programming Design Paradigm
Aspect Oriented programming (AOP) decomposes a system into concerns (i.e. term referring to the core elements required to focus on), instead of objects. It deals with ?aspects? that cross-cuts across the code which could be difficult or impossible to modularize with OOP.
Seperation of concerns (SoC)
AOP promotes separation of concerns within the systems where separation of concerns (SoC) is a process to break a computer program into distinct features that were previously overlapping in functionality, as little as possible. A concern is any piece of interest needed to focus on while developing a program. Typically, concerns are synonymous with features or behaviors, lets talk of a credit card processing system, the related core concern of the system deals with processing the monetary transactions, while its application-level concerns handles logging, transaction integrity, authentication, security, performance, and so on.
