Analysis of the interdepartmental information exchange processes

The article deals with various scenarios of the interdepartmental information exchange system formation. They differ in the ways of the system core integration models formation. The first scenario assumes a minimal integration in the kernel of frequently encountered basic concepts. In the second case, the initial formation of the integration core ontology, approaching the full composition of the basic elements, is carried out. Integration of automated information systems (AIS) is carried out taking into account the existence of this core, but without changing it. The third scenario provides the formation of the core by attaching the ontologies of AIS as they integrate without creating an initial integration core. The comparison of these scenarios by costs is carried out, the optimal scenario is defined. Two examples of national systems of interdepartmental exchange are considered.
