. Failover Cluster protects the instance, while DB
Mirroring protects one or more DBs.
2. failover clustering required dedicated H/W, while DB
Mirroring is not required dedicated h/w
Database mirroring maintains two copies of a single database that must reside on different server instances of SQL Server Database Engine. Typically, these server instances reside on computers in different locations. Starting database mirroring on a database, initiates a relationship, known as a database mirroring session, between these server instancesDatabase mirroring involves redoing every insert, update, and delete operation that occurs on the principal database onto the mirror database as quickly as possible. Redoing is accomplished by sending a stream of active transaction log records to the mirror server, which applies log records to the mirror database, in sequence, as quickly as possible. Unlike replication, which works at the logical level, database mirroring works at the level of the physical log record. Beginning in SQL Server 2008, the principal server compresses the stream of transaction log records before sending it to the mirror server. This log compression occurs in all mirroring sessions
the difference is about the transactions. the normal database is not included deadline, but the real time database is.
Database is the data stored in the server and Database administrator is the person who designs the database.
