There are things I am not quite sure of. So I have done some further research on which flows should I be using in each scenario and talked with some gurus in those areas. Now I have the confidence to talk about it. So here it is. Is it the most difficult exam in the architect series except CTA? For me, kind of.

Has everyone read the cool pattern provided by financial force called Unit of Work? It is a really cool pattern.
