This section defines the Infrastructure Communication Channels (ICC) though which the systems
shall exchange information. The definition of ICCs was based on the business requirements for
exchanging information among the systems. These business requirements are expressed through the
“Business Communication Channels” (BCC). Since the interactions among the systems may be lot,
CDPS System Integration is presented per system by defining its BCC and ICC with the other
systems.
5.3.2 Integration Architecture
In [R16] we proposed the existence of a separate integration tier in the logical architecture of
CDPS. Integration tier is separate from the implementation of the other tiers: integration with
additional software systems from the Common, National or External Domain, and removal of
existing integration with software systems will have no implications on the implementations of the
other tiers. For sake of completeness, here we reproduce the diagram from [R16] which gives a
more detailed presentation of the Data Integration Tier.
