Hub & Spoke-concept
The Hub & Spoke-concept refers to a parent or holding company that uses one business software system (the hub), which is integrated with the systems used by its individual subsidiaries or divisions (the spokes). This concept is a metaphor, which uses the image of a wheel with a core component (the hub) and many sub-components (the spokes). Together, the hub and spokes form a whole that can progress forward as one unit.
