Abstract

A method of synchronizing databases between multiple users in a peer-to-peer network is disclosed. The method comprises extracting changes from a source database of one of the users. Next, the changes are compressed and sent to the other users in the peer-to-peer network in parallel. Finally, the changes are decompressed and replicated on the database of each of the other users. In this respect, the databases of the other users will contain all changes from the source database.

Claims

1. A method for peer-to-peer database synchronization between a first computer and a second computer, the method comprising the steps of:

a) extracting changes from a source database of the first computer to generate an extracted database;

b) transferring the extracted database from the first computer to the second computer; and

c) replicating the source database on a target database of the second computer from the extracted database in order to synchronize the target database with the source database.
