Gradually to synchronize the target data with source data,
there are further 2 techniques:-
Refresh load - Where the existing data is truncated and
reloaded completely.
Incremental - Where delta or difference between target and
source data is dumped at regular intervals. Timsetamp for
previous delta load has to be maintained.
