Snapshot replication in DBMS

Question

What do you understand by the term snapshot replication in DBMS?

Answer 1

Snapshot replication can be employed if an application does not necessitate that the data always be current. Such applications can be updated by periodic table snapshots or copying. As part of the snapshot effort, all of the data to be consisted in the snapshot is collected at a primary point. And then a read-only snapshot is taken and is sent to each and every site and hence the update can be made.
