Abstract
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.
