What is the difference between shared locks and exclusive locks?

What will be an ideal response?


Shared locks allow other transactions to read but not update a record or other resource. This is most useful when preventing another user from placing a lock on a record. An exclusive lock prevents another transaction from reading and writing a record until an update is done by the transaction that locked the record.
