In the IBM Graphics Product 5668-941, the three basic data models are point, span and control facilities. Each is attached to an absolute point via the point connectors. A point facility models, for example, an electric pole while a span facility can represent a power line. Both can be connected logically, or electrically, depending on how the point connectors are displayed in a work space screen. A water valve may locate at one point, but it has two different connections, for example, to two different ends of two span facilities, and both ends and the valve itself are located at one point. The valve is modeled by the control facility. The span facilities are well suited for a distribution network system.
