PROBLEM TO BE SOLVED: To perform fraction processing so as to secure a total rate of 100%, etc., for a component ratio of numerical data on every data item in regard to a table consisting of plural data items. SOLUTION: Numerical data on plural data items are set on a numerical data table 3 which includes breakdowns and numerical data on the components of a lower order level of a certain data item. A definition data table 5 defines a level hierarchy of each data item corresponding to the table 3. Then a component ration calculation part 4 refers to both tables 3 and 5 to calculate the component ratio of a data item of the most significant level and performs fraction processing so as secure the total component ratio of 100%. Then fraction processing is performed again so as to secure the total component ratio of both breakdowns and components that is equal to the component ratio of the immediately higher order level. However, temporary dummy data are set for the components since they treated equivalent to the breakdowns. |
