PingDataSync processes changes by fetching the most
up-to-date, full entries from both sides and then compares 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.
