space hierarchy

The hierarchy determining how space is organized in a facility. Archibus assumes a space hierarchy of sites owning buildings, buildings owning floors, and floors owning rooms. Within the Space hierarchy, the Buildings, Floors, and Rooms tables form a strict hierarchy, such that the owning building and floor values contribute to a room's primary key. The Sites table is not part of the strict hierarchy; a site can own a building, but does not contribute to the building's primary key.
