Call Transaction is faster than session method because
while updating data into database call transcation does not
check the updation but it check the success of the
transaction only . where as Session method ,check the
updation of the data into database and also success of the
transaction. That's the reason call transaction is faster
than Session method.

In call transaction Synchronous updation is Optional.

If u wnat to send data & update the data at different times
& want to update data synchronously then need a automatic
error log, then we go for Session method . It is slow.

if call transaction the data that is received will be
updated at the same time.
