Conventionally, since consideration has only been given to speeding up heap structures, there has been a problem that in continuous session processing, for example, there has not been a sufficient mechanism for parallel operation of execution assessment processing and heap processing. By providing a maximum priority data decision signal from a database update unit to a database update assessment unit, outputting the fact that a decision has been made at the moment when the maximum priority data is decided during database update processing, and carrying out database update assessment processing using the maximum priority data, the present invention makes it possible to operate the database update unit and database update assessment unit in parallel and improve processing speed. |
