Abstract: One or more interconnected facility equipment databases store one or more interconnected facility equipment data files predetermined for a specific facility. The interconnected facility equipment data files include facility location data files and facility equipment data files associated with equipment located within a facility to indicate operating status of the equipment, separate from control of facility equipment, in specific facility locations during operation. A facility maintenance user accesses the interconnected facility equipment data for maintenance, repair, or operating status purposes. The facility maintenance user accesses the data through a graphical user interface readily navigable by the facility maintenance user in a direct, interrelated, non-sequential, and non-ordered arrangement of user selections so as to define a multidimensional lattice arrangement, thereby allowing freedom of movement within the multidimensional lattice arrangement.
