PROBLEM TO BE SOLVED: To solve the problem that conventionally the loss of the consistency of internal data stored in a transaction processor can not be surely prevented in the case that communication between the transaction processor and terminal equipment is interrupted or an operation is stopped in the middle of the processing of the transaction processor. ;SOLUTION: Relating to an executed transaction, a flag for indicating that the processing is normally completed is imparted and an executed result is recorded as history information 8 by a history information storage processing part 7c corresponding to an execution instruction T and identification information ID inputted from the terminal equipment. Thereafter, when a transaction execution instruction T and the identification information ID are inputted from the terminal equipment, by a history confirmation part 7a, the history information 8 is retrieved with those pieces of the information as keys and the presence/absence of the normally ended executed result corresponding to the execution instruction T and the identification information ID is discriminated. When it is present, by a history acquisition part 7b, the executed result is read and outputted to the terminal equipment. When it is absent, a new transaction is executed and the executed result is outputted to the terminal equipment and recorded as new history information 8.;COPYRIGHT: (C)2001,JPO
