Abstract
An object of the present invention is to carry out transaction processing on a plurality of records even in the case the transaction processing is executed in an environment that manages records composed of pairs of keys and values. The transaction processing device of the present invention includes a group information storage unit that stores information relating to transactions, in association with information relating to groups generated by logically grouping records used in the transactions according to attribute values of a unique key common to the records, a group specification unit that specifies the group corresponding to the transaction by referencing the stored information based on the transaction corresponding to a processing request received from the application, a log management unit that manages logs of the records belonging to the specified group by collectively storing all contents of the logs in the physically same storage area, and a data updating unit that updates real data by reflecting the contents of the managed logs in the records corresponding to those logs.
