Physical-economy data is almost always sold as separate feeds: a freight feed, a weather feed, a power feed, a hardware tracker. A feed can tell you that a vessel sailed and that a substation filed for an upgrade. It cannot tell you that the vessel is carrying the transformer the substation is waiting for, or that a campus energization date moves when either one slips. That gap is where the decision actually happens, and it is the part no feed holds.
Nuclir stores the relationships rather than the rows. A facility connects to the capacity it holds, the power it draws, the equipment on order, the routes carrying it, and the weather sitting over those routes. "What is constraining this build" becomes a path through those connections instead of four browser tabs and a judgement call.
It is also why the answer moves without anyone asking again. When a shipment clears, a queue position changes, or a storm track shifts, one relationship changes and every question routed through it answers differently the next time it is asked - in the Console and over the API at the same moment.
