PROBLEM TO BE SOLVED: To provide a POS data managing method which shortens a time between a summing up start of transaction data and a summing up end and reduces a possibility that summing up processing on a normal operation date is disturbed even though a failure occurs in a transmission path from a POS terminal to a server. SOLUTION: In the summing up processing of transaction data from the POS terminal, the entire transaction data are once stored and held in a primary database 31 of the server 30 without depending on a date (timing) when the transaction data are recorded as real results, and are subsequently transferred to a secondary database to be summed up. |
