How OneSurvey models the physical world.

Entity creation order

Organization → Site → Building → Floor → Area → Device

Each entity is created inside its parent. You can't add a device until you have an area; you can't add an area without a floor.

Why it matters

This hierarchy powers reporting, access scoping, and lifecycle tracking. Devices roll up to areas, areas to floors, floors to buildings, and so on.
