In pessimistic locking when user wants to update data it locks the record and till then no
one can update data. Other user’s can only view the data when there is pessimistic locking.
In optimistic locking multiple users can open the same record for updating, thus increase
maximum concurrency. Record is only locked when updating the record. This is the most
preferred way of locking practically. Now a days browser based application is very common
and having pessimistic locking is not a practical solution.
