Abstract Aspect-oriented programming (AOP) is a novel
programming paradigm that aims at modularizing complex
software. It embraces several mechanisms including (1)
pointcuts and advice as well as (2) refinements and collabo-
rations. Though all these mechanisms deal with crosscutting
concerns, i.e., a special class of design and implementation
problems that challenge traditional programming paradigms,
they do so in different ways. In this article we explore their
relationship and their impact on modularity, which is an
important prerequisite for reliable and maintainable soft-
ware. Our exploration helps researchers and practitioners to
