FIELD: information technology. ^ SUBSTANCE: unique keys of record types are centrally generated, and types with possible duplications are tagged and sent to databases. When record instance is saved to database own unique key is generated and saved, and when tag is present, in the absence, centralised unique key for the instance is requested and saved. When exchange is generated tagged instances are supplemented with centralised unique instance key. At receive of exchange, the presence in database of records available in exchange array is identified and links to own records are readdressed. The system contains devices and units to store unique keys of types and tags, to operate requests, and in databases - devices and units: for storing unique keys of types and tags, for control, generation, receive, transformation of exchange arrays. ^ EFFECT: functionality enhancement due to elimination of extra bidirectional exchanges between databases. ^ 2 cl, 5 dwg |
