I use "behavior" to mean "anywhere in C++ that you can put a breakpoint". Structure is the places where you can't.

(That implies more dynamic languages, such as Ruby, express more structure with executable lines. So "behavior" in Ruby is less than all the places you could put a breakpoint.)

Hence "Designing a program requires balancing its structure in memory with its behavior in time."

And I don't agree that calling databases "non-behavior-centric" is helpful. Just because you can't put a C++ breakpoint there doesn't mean they don't behave...
