摘要

PROBLEM TO BE SOLVED: To provide a shared data management system, method and program, allowing reflection of change contents in each terminal with a small load even if a change occurs in shared data when the plurality of terminals connected to a network manage the shared data.;SOLUTION: Virtual computer servers 12, ..., 12 each configures, in software, an optional number of virtual computers each having a peculiar address on the network, each disposed on the network, and each virtually holding the shared data in one-to-one correspondence with each of the plurality of terminals 11, ..., 11. When a distribution time of the shared data of a shared data distribution means 13 exceeds a threshold value, at least a part of the virtual computers is integrated to one of the virtual computer servers 12 to reduce a load on the network.;COPYRIGHT: (C)2011,JPO&INPIT
