Due to differences in the economic environment and other circumstances in a company, individual businesses create data with various attributes and the like. For this reason, companies have not always been able to make full use of their corporate data in association with various corporate data provided from external organizations. Therefore, the present invention provides a system facilitating the analysis of company data while incorporating external data. Using n-row by m-column two-dimensional tabular data, the system sets totaled values for columns to internal data and totaled values for rows to external data and calculates the values of cells, while performing analyses associated with the external data. The system calculates values in six cells from two sets of tabular data condensed to two rows and three columns and calculates the values in each cell of the n-row, n-column original table.
