A system and method of replicating database records for use in resource constrained wireless computing devices. The replication method has a low processing burden and is well suited to low-bandwidth, unreliable connections found in many wireless networks. To reduce the amount of memory used on the wireless device only a change log record is time-stamped, not every database record. The change log defines what data is to be replicated and needs to sent to a main server that hosts a master copy of the database. The change log is made compact to reduce the amount of data that needs to be sent for data replication by only requiring the field that has changed in a record and a timestamp to be sent, not the entire record in which the change was made.
