Aspect-oriented programming (AOP) is the idea of decoupling and modularizing cross-cutting concerns. Cross-cutting concerns are concerns that span over multiple objects in object oriented programming. Common examples are tracing, logging, and auditing, but there are many different cross-cutting concerns.
Using Aspect-oriented programming is made simple by the libraries that exist. For Java, there is AspectJ. For C#, there is PostSharp.
