PURPOSE:To compare in order of accessing record concurrently with comparison of the data contents by utilizing the results of comparison between the record type information and the level information on each data stored in a hierarchical data base. CONSTITUTION:Not only the data contents but the data access orders are compared with each other by means of the results of comparison between the record type information and the level information on each data stored in a hierarchical data base. In other words, the correspondence of records is decided by comparing the record of a reference side data base 300 and that of a comparison side data base 400 and judging the result of this comparison. Thus no correspondence is secured among those records having different access orders and the comparison of records is impossible in terms of access orders.
