A system and method for merging a first database with a second database (one-way merge), and a system and method for merging two databases with one another (two-way merge) is described herein. During the one-way merge, new or updated records are transferred from a copy of a client database to a server database after it is determined that the server database either does not contain one or more records in the copy of the client database or contains an older version of one or more records in the copy of the client database. During the two-way merge, new or updated records are transferred between a client database and a server database after it is determined that either the client database or the server database does not contain one or more records in the other database or contains an older version of one or more records in the other database.
