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.
