There is provided a data processing system including nodes each configured to retain data used for providing a user group with a service in units of one or more users serving as a part of the user group, and a routing manager configured to, in response to an access request to the data from the one or more users, perform routing to the nodes in which data of the one or more users is stored. The nodes include a first node for retaining master data of the one or more users, a second node for retaining slave data obtained by replicating the master data, and a third node. The muting manager further performs data movement processing involving changing the slave data retained in the second node into the master data, also replicating the slave data, and causing the third node to retain the replicated slave data as new slave data.
A data processing system comprising:
A data processing apparatus comprising:
A non-transitory computer-readable storage medium having a program retained therein for causing a computer to achieve a function, the computer being connected to a storage retaining slave data obtained by replicating master data used for providing one or more users with a service,
