Abstract
In a data utilizing system, a statistic table exhibiting a characteristic distribution is automatically extracted from given statistic tables of data. After confirmation of distribution of the data on the extracted statistic table, data required is retrieved from the statistic table. The data utilizing system for extracting from data constituted by a set of records each composed of at least two item values each containing at least one numeric item value, a part of the records constituting a part of the data, includes: as statistic table list generating unit for generating from the data statistic tables of component data for which at least one item value is definitely specified, and for determining arithmetically characteristic quantities for the statistic tables, respectively, on the basis of differences between the statistic tables and relevant expected value distribution tables, to thereby generate a list of the statistic tables on the basis of the characteristic quantities; and a record list generating unit for generating from the data a list of records contained in all or at least one specified cell of a specified given one of the statistic tables.
