Re: when to use component-based design vs. stayign with traditional OOP

Sorry, I've not followed the complete discussion.

I saw a presentation by Gregor Kiczales on Aspect-Oriented
programming.

-------------------------------------------

http://en.wikipedia.org/wiki/Aspect-oriented_programming

Aspect-oriented programming (AOP) is a programming paradigm that
increases modularity by allowing the separation of cross-cutting
concerns, forming a basis for aspect-oriented software development.

Cross-cutting concerns: Even though most classes in an OO model will
perform a single, specific function, they often share common,
secondary requirements with other classes. For example, we may want to
add logging to classes within the data-access layer and also to
classes in the UI layer whenever a thread enters or exits a method.
Even though the primary functionality of each class is very different,
the code needed to perform the secondary functionality is often
identical.

-------------------------------------------

AOP helps with logging and security which are archetypal cross-cutting
concerns.

AOP'ers are trying to find uses for AOP outside of these areas.

Kiczales argues that OOP suffers from a limitation called the tyranny
of the dominant decomposition.


So, I'd reccomend component based design if the tyranny of the
dominant decomposition is getting to be too challenging.
