<p><P>PROBLEM TO BE SOLVED: To improve an information processing system on which an in-memory database is loaded. <P>SOLUTION: This information processing system includes a plurality of server devices on each of which an in-memory database for storing processing object data is mounted. The same processing object data are stored in each in-memory database of each server device, and the master data of the processing object data are arranged so as to be distributed in any one of the server devices, and slave data corresponding to the master data are arranged in the other server device in which the master data are not arranged. The server device includes in-memory data management means for, when the master data of the processing object data whose processing request has been received are arranged in the self-device, performing the requested processing to the master data, and for performing copy processing to the slave data arranged in the other server device corresponding to the master data. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
