Synchronization occurs via messaging<br />
• Replica pairs synchronize through messages<br />
– Data change message—includes data changes<br />
• All changes since last acknowledgement<br />
– Acknowledgement message<br />
• Data receiver acknowledges receipt of changes<br />
– Switch roles message<br />
• Data receiver now can send changes to replica relative<br />
• Online synchronization (connected on same<br />
network)<br />
– <strong>ArcGIS</strong> manages messages<br />
• Offline synchronization (not on same network)<br />
– Manual messaging required<br />
