What is Replication and Database Mirroring?
Submitted by: Administrator
Database Mirroring allows two copies of a database on different computers. Clients can get access to only one database called as”principal” database. Any changes applied to principal database, are applied on the copy also called as the mirror. This is achieved by applying the transaction log for every insert, update, or deletion made on the primary database. This increases the availability of a database incase of a failure.
