<p>PROBLEM TO BE SOLVED: To accelerate response speed in the case where collection for information is requested.SOLUTION: A processor 201 detects and registers a pattern in which a certain event is a head event and an event subsequent to the head event is a subsequent event from an event sequence. In the case where, after a first event and a second event subsequent to the first event is acquired, the first event is re-acquired, the processor searches a read-ahead target pattern in which the first event is the head event from the registered pattern group, and writes internal information corresponding to a subsequent event to the first event out of the read-ahead target pattern from a first storage part 311 into a second storage part 312. The processor determines whether or not internal information corresponding to a subsequent event, which is acquired after the reacquisition of the first event, exists in the second storage part 312, and when it is determined that the information exists in the second storage part 312, the processor reads out the internal information corresponding to the subsequent event from the second storage part 312.</p> |
