Abstract: A server can be connected to a dispenser configured to dispense a dispensed material. The server includes a retrieving module configured to retrieve skin information on a user's skin condition, a determination module configured to determine recipe information for the dispensed material with reference to the skin condition indicated by the skin information, a transmission module configured to transmit the recipe information to the dispenser to cause the dispenser to dispense the dispensed material in accordance with the recipe information, and an arrangement module configured to arrange for the provision of an additional cartridge to the user of the dispenser if the remaining amount of the dispensed material remaining in the cartridge of the dispenser is less than a predetermined threshold.

Abstract: A data management system including an AP server and a DB server. The AP server sends business data to the DB server and requests registration. The business data includes combination of parent data and a plurality of pieces of child data with mutual relevance, and each child data has ID of the parent data. In registering business data, the AP server first tries to register each child data, and requests registration of the parent data when a notification of registration completion of all pieces of the child data arrives from the DB server. When the notification of registration completion of any of the child data has not arrived, the AP server cancels the registration of the parent data. In referring to the business data, the AP server sets only child data with related parent data registered therein as a target.
