An interserver data association apparatus capable of making data association with respect to a plurality of reception servers based on data transmitted from one transmission server. Transaction information about the manipulation of a database sent from a main center is received by an acquisition unit in the interserver data association apparatus. The data received by this acquisition unit is transferred to individual distribution buffers in a distribution unit. This distribution unit has information about the timings of data transmission requested by the individual reception servers. At the timing each reception server requests, therefore, the distribution unit transfers the transaction information stored in the distribution buffer associated with each reception server to that reception server.
