Zusammenfassung:	In a method of controlling a database including an aggregate item for recording an aggregate value of transaction volume included in transaction data recorded in a blockchain, a computer executes a process of obtaining a plurality of the transaction data recorded in the blockchain, a process of specifying, for each of a plurality of second users who are transaction partners with a first user associated with the aggregate item, a transaction time with the first user on the basis of the plurality of transaction data, a process of classifying the plurality of second users into a plurality of groups on the basis of dissimilarity of the transaction time, and a process of generating the aggregate item for each of the groups in the database, thereby suppressing a conflict in database updating.
