What is Bidirectional Sync?
A data synchronization method where changes flow in both directions between two systems, keeping records updated in both places automatically.
Bidirectional sync (also called two-way sync) ensures that when a record is updated in System A, the change is reflected in System B, and vice versa. This is more complex than one-way sync because it requires conflict resolution - determining what happens when the same record is modified in both systems simultaneously. Common conflict resolution strategies include 'last write wins', source system precedence, or manual review. Bidirectional sync is essential for maintaining data consistency when multiple teams work in different systems.
