PingDataSync processes changes by fetching the most up-to-date, full entries from both sides and then comparing them. This process flow is called standard synchronization mode.
The processing flow differs depending on the type of PingDataSync change (ADD, MODIFY, DELETE,
MODDN) that is requested. The following examples show the control flow diagrams
for the sync operations, especially for those cases when a MODIFY or a
DELETE operation is dropped. The sync log records all completed and
failed operations.
