What are the different types of replication supported by SQL SERVER?
There are 3 types of replication supported by SQL SERVER which are shown below:-
1) Snapshot Replication:
The Snapshot Replication takes snapshot of one database and moves it to the another database. After the initial load the data can be refreshed periodically. The only demirt of this type of replication is that all data has to be copied every time the table is refreshed.
2) Transactional Replication:
In the transactional replication the data is copied first time as in snapshot replication, but later only the transactions are synchronized rather than replicating the entire database.You can either specify to run continuously or on the periodic basis.
3) Merge Replication:
The Merge replication combines data from the multiple sources into a single central database.As usual the initial load is like snapshot but later it allows the change of data both on subscriber and the publisher, after that when they come on-line it detects and combines them and updates accordingly.
