Abstract:
1. A data deployment system comprising: a deployment-source device including a first database which stores first data; and a deployment-destination device to which the first data stored in the first database is deployed, wherein the deployment-source device includes: a first generation unit which generates first identifiers corresponding to a plurality of first fragmentary data, into which the first data stored in the first database is divided; and a second generation unit which generates, when the first data is updated to second data, second identifiers corresponding to a plurality of second fragmentary data, into which the second data is divided, and the deployment-destination device includes: a second database which stores the first data that is stored in the first database and the first identifiers that are generated by the first generation unit; a determination unit which determines whether the first identifiers stored in the second database are identical to the second identifiers which correspond to the first identifiers and are generated by the second generation unit; and a write unit which writes in the second database the second fragmentary data corresponding to the second identifiers and the second identifiers when the determination unit determines that the first identifiers are not identical to the second identifiers which correspond to the first identifiers.
