摘要

PROBLEM TO BE SOLVED: To provide a device and a method by which average loads on an inquiry to a database are reduced, and a memory use capacity is decreased drastically, while an effect of batch update is enhanced by increasing the number of update requests to be flashed at a time. SOLUTION: This device is provided with: an accumulation part 32 for accumulating update requests of a database; an update part 33 for performing batch processing of the accumulated update requests and updating the database; and a processing part 34 for inquiring the database and for generating the output of an inquiry result. The device is further provided with: an extraction part 35 which acquires the update request from the accumulation part 32 in response to an input of the inquiry and extracts an update request which influences the inquiry result on the basis of the inquiry content; and a content change part 36 for changing the inquiry content by using the update request extracted by the extraction part 35 and generating the input of the inquiry of the changed content to the processing part 34.
