Abstract
A computer implemented method and a computer program for synchronizing a first and a second database, where data is provided for keeping track of whether the records of the first database have been added or changed since a previous synchronization. Based data reflecting whether the records of the first database have been added or changed since a previous synchronization, it is determined whether the records of the first database have been changed or added since the previous synchronization. If one of the records of the first database has not been changed or added since the previous synchronization, a synchronization with records of the second database is performed using a record representative of the one record at the time of a previous synchronization. The representative record is stored in a history file which contains records reflecting the contents of records of the databases at the time of a previous synchronization.
