Database replication
From DocForge
Database replication is the process of duplicating database servers in near real-time, usually across multiple physical servers. It's usually implemented to increase overall application performance by distributing queries or to have an always-ready backup.
[edit] Types of Database Replication
- Master/Slave Replication
- One or more servers are designated masters, sending queries or data to slaves on a periodic or continual basis. Masters may notify slaves of pending updates or slaves may poll the master for changes.
[edit] Database Servers Supporting Replication
Many database servers have built-in support for various forms of replication.
