We describe an approach to the realisation of CIM systems
through the coordination of autonomous component systems
based on the exploitation of multidatabase
technologies. Each component system is augmented by a CIM
Agent which provides a coordination interface; the interface
specifies globally important local objects in terms of a
global semantic data model. System-wide consistency is
ensured through the management of global constraints by a
central coordinator along with cooperative multi-level
transaction schemes. The CIM Agents are responsible for
monitoring local activities and notifying the central
coordinator of updates relevant to global consistency; they
are also responsible for initiating local actions necessary
for the maintenance of system-wide consistency as delegated
by the coordinator.
