The present invention relates to a method for synchronizing databases in a network environment. Specifically, the present invention pertains to a method of using a set of hierarchical rules to enable an efficient and speedy synchronization between multiple copies of a database. The present invention enables an“n-way”synchronization of databases where“n”, the number of databases synchronized, is essentially any number more than two. In one embodiment, the present invention provides rule-based, n-way, synchronization by selecting a focus copy of the database, comparing the data records of the focus copy against the same records in other copies of the database to identify those deleted and modified; removing all the records indicated to be deleted, modifying those to be modified, and adding new record identifiers in the case of multiple modifications to the same record.
