Be a little careful about pieces in Bloomberg about the JCPOA. I read Bloomberg about as much as I read stuff like Slate, and the sense I have is that Bloomberg's editorial stance has been anti-JCPOA for a long time.

As it stands, this article is basically saying "$DATABASE is at the heart of the Iran nuclear deal", which is about as interesting as saying "Excel is at the heart of such-and-such a merger deal". Like, yes, you do use databases to track stuff, indeedly-do.
