      Answer :

      Locking a record for longer than required can result in unnecessarily long waiting times. The use of delayed locks solves this problem to a great extent.

Immediately before updating the database, the system reads the value of the record again, this time placing a lock on it.

      the rst read with the content from the second read. If changes have been made to the record by another process since the rst read, the error ROWCHANGED is returned and the transaction is undone.
