What is the difference between functional and behavioural models in sofrware engineering? what are examples of each?

All behavioural models really do is describe the control structure of a system. This can be things like:

All functional models really do is describe the computational structure of the system. On the other hand, this system – even though it may have many Use Cases – should only have one functional model, yet this may be composed of many functional diagrams.

loool i m also trying to figure that out.seems like u should have genius ranking

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
