Abstract
Methods and systems for synchronizing data may enable a computer to synchronize data by connecting to a peer computer via a network connection. The computer may receive a remote table from the peer computer, wherein the remote table comprises an object comprising a vector. The computer may determine whether the object is present in a local table. When the object is present in the local table, the computer may determine whether the vector in the remote table and the vector in the local table match. When the vectors do not match, the computer may determine whether a record of a change to the object is present in a local transaction log. The computer may receive data from the peer computer indicating whether a record of a change to the object is present in a remote transaction log when the vectors do not match. The computer may replace the vector in the local table with the vector in the remote table and record a change to the object in the local transaction log when the record of the change to the object in the local transaction log is less recent than the record of the change to the object in the remote transaction log.
