  • strongData Replication/strong is the process of storing data in more than one site or node. It is useful in improving the availability of data. It is simply copying data from a database from one server to another server so that all the users can share the same data without any inconsistency. There are three types of data replication.They are:1.Snapshot Replication 2.Transactional Replication 3.Merge Replicationbr /1.Snapshot Replication :emSnapshot replication/em simply takes a "snapshot" of the data on one server and moves that data to another serverbr /2.Transactional Replication:emTransactional replication/em involves copying data from the publisher to the subscriber(s) once and then delivering transactions to the subscriber(s) as they occur on the publisher.br /3.Merge Replication:emMerge replication/em combines data from multiple sources into a single central database. Much like transactional replication, merge replication uses initial synchronization by taking the snapshot of data on the publisher and moving it to subscribers.br /
