See full text

The first DS in accordance of the inquiry from the integration server, extract first data from the first DB and generate a first hash value based on the first data. The second DS in accordance of the inquiry from the integration server, extract second data from the second DB and generate a second hash value based on the second data. The first DS transmits the first hash value to the second DS. The second DS collates the first hash value with the second hash value, transmits, to the integration server, a collation result and at least a part of the second data, for which the first hash value and the second hash value are matched, and transmits a matched part of hash values to the first DS. The first DS transmits at least a part of the first data that was a source of the matched part of hash values to the integration server. The integration server combines the data received from the first DS and the second DS on the basis of the collation result.
