Aspect aspect-oriented programming is known as a technique for modularizing crosscutting concerns. However, there are no clear rules to help detect and implement aspects in the software development lifecycle. Consequently, class developers face changeability, parallel development and comprehensibility problems, because they must be aware of aspects whenever they develop or...
