We discussed some open research issues that should be addressed in the comprehension and maintenance of AO software, and gave a brief overview of the work in progress in this area. Some research results are quite encouraging, but many work still needs to be done to support the maintenance of AO software.
In this paper, early aspects deal with crosscutting concerns in requirements analysis, domain analysis and architecture design. Work on early aspects focuses on systematically identifying, modularizing, and analyzing such crosscutting concerns and their impact at the early phases of the software development life cycle.
Aspect-oriented programming (AOP) strives to localize the scattered and tangled implementations of crosscutting concerns (CCCs) by allowing developers to declare that certain actions (advice) should be taken at specific points (join points) during the execution of software where a CCC (an aspect) is applicable. However, it is non-trivial to construct optimal pointcut expressions (a collection of join...
