摘要： When update information with respect to a first database or a second database is received, a database update control apparatus updates the first database or the second database on the basis of the update information. When updating the first database or the second database, the database update control apparatus associates pre-update data with an identifier that is added to the update information and retains them for each database. The database update control apparatus extracts, for each database from among the retained identifiers, an identifier that indicates the latest update information and specifies, from the extracted identifiers, an identifier that is the oldest updated identifier. The database update control apparatus reflects pre-update data associated with an identifier that is newer than that specified in a corresponding database out of the first database and the second database.
