snapshot isolation level (n)~ A transaction isolation level in which each read operation performed by a transaction returns all data as it existed at the start of the transaction. Because a snapshot transaction does not use locks to protect read operations it will not block other transactions from modifying any data read by the snapshot transaction. snapshot replication (n)~ A replication in which data is distributed exactly as it appears at a specific moment in time and does not monitor for updates to the data.
