Aspect Orientation-A New Approach to Programming

Currently the main stream programming paradigm is Object Oriented Programming: OOP, which has gotten great success. The advantage of OOP is that it provides effective modularity support, and enables direct mapping from requirement space to design space, etc. However, there are still some specific requirement and design issues, e. g. , security and logging, which are hard to be implemented with clear modularity using either procedural or OOP techniques. In fact, the code of this kind of concerns are often scattered through out the whole system, resulting in some ugly scattering code and tangling code.Such kinds of programs are often difficult to develop and maintain. Recently a new programming paradigm-Apect Oriented Programming: AOP, which aims at solving the crosscutting concerns, has gained much popularity. This paper is an overview of AOP.
