CUSTOMER DATABASE MERGE METHOD AND MERGE PROCESSING PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM RECORDED WITH MERGE RELATIONAL DATA

PROBLEM TO BE SOLVED: To provide a new merge relational database and an enrichment service whose additional value is high by enlarging/activating the available range of a customer database and an investigation data base. SOLUTION: A processing part reads each customer data from a customer database and each investigation-targeted person data from an investigation database (S101). The processing part sets purpose variables corresponding to a desired investigation purpose on the basis of the customer data or the investigation-targeted person data and common entries between the customer data and the investigation-targeted person data (S105). The processing part calculates the weight of each common entry for the purpose variables by methods such as preliminary setting or regression analysis (S107). The processing part decides the investigation-targeted person data close to each customer data as matching data on the basis of the common entry and weight (S109). The processing part prepares fused data by making the customer data and the investigation-targeted person data decided as matching data correspond to each other, and stores the merged data in a merge relational database (S111), and executes processing related with transmission (S113).
