FIELD: methods and means for setting up informational exchange between computer systems.
SUBSTANCE: in the method, exchange files are formed, which are placed into storages of exchange files of each computer system, made with possible storage and selection of exchange files, checking of correctness of data contained therein, generation and execution of requests for replacement of incorrect data. Exchange files are transferred between main and peripheral computer systems, correctness of received files is checked and in case of incorrectness, exchange files are repeatedly transferred. Reference integrity of data is checked in intermediate database, on negative result of check, data replacement request is formed and incorrect data is replaced, check is performed again, and on positive result of check, data is transferred into main database. To check correctness of performed replication, hash sums are generated for corresponding records in main databases of main and peripheral computer systems.
EFFECT: ensured identity of information being replicated during data transmission between computer systems.
