SYNCHRONIZATION OF DATABASE DATA

摘要

A method of arranging synchronization of databases, the method comprising th e steps of establishing a transport layer connection for synchronization betwe en a first and a second device which synchronize databases. During initializati on of synchronization a first update identifier, which is stored at least in th e first device and describes the latest synchronization event the devices have performed in the databases, and a second update identifier, which is defined by the first device and describes the present synchronization, are transmitt ed from the first device to the second device. The second update identifier is stored in the first and the second device. The contents of the first update identifiers stored in the devices are updated in the first and the second device if synchronization has been performed and after this said transport layer connection has been ended substantially properly.
