PROBLEM TO BE SOLVED: To construct a database to analyze a member's game preference by setting uniquely numerical values by users or by setting formulas for computing treated data. SOLUTION: A setting input of a fixed period for performing a member analysis and a setting input of custom data are received. In the case of the setting input of custom data, a data name of the setting data and a formula for computing the data can be input. An operation computer, extracting effective data applicable to the fixed period, calculates used money amount and played data including out and safe numbers, and also counts the number of playing times, the frequency of visits to a game hall and the number of played game machine models. The custom data are computed according to the settings following the formulas for calculating the data, and a data storage file for member's analysis is created by storing member identification data, computed used money amount and playing data, the counted number of playing times, the number of visits to the game hall and the number of played game machine models, and the data name together with the computed custom data.
