Database Replication

Definition - What does Database Replication mean?

Database replication is a technique through which an instance of a database is exactly copied to, transferred to or integrated with another location. Database replication enables the copying of a database file from a master database management system (DBMS) and its exact deployment on a slave DBMS.

Techopedia explains Database Replication

Database replication is primarily used in distributed DBMS environments where a single database is deployed, used and updated at several simultaneous locations. Database replication is generally performed frequently in a transactional database that is routinely and dynamically updated. Typically, database replication is done to provide a consistent copy of data across all the database nodes. It also removes any data redundancy, merging of two databases into one and updating slave databases with outdated or incomplete data.

Database replication has three distinct types:

  • Transactional replication
  • Snapshot replication
  • Merge replication
