Two-way Sync (Fast Sync)

Two-way sync, also called fast sync, is the normal synchronization mode, in which the client and the server exchange modifications to the data that they have stored. An initial slow sync is used to populate the data on the client.

The client always initiates this exchange by sending client data modifications to the server. This is called a synchronization request.

The server processes the synchronization request, comparing and unifying the data from the client with the data in the server database by means of an Enterprise Connector.

Afterwards, the server sends the modified data to the client, which updates the local data store with the information from the server. Figure 1–5 illustrates this process.
