Database Replication

Database Replication

Database replication in Information Technology refers to the act of copying or writing the same or different files from one user to another through the same databases.

Reasons for Replication

* To provide a backup copy of the data in case the original database is lost or damaged.
* To improve performance by distributing the load across multiple servers.
* To make the data available to users in different locations.

TYPES OF REPLICATION

* **Master-slave replication:**

In this type of replication, there is one master database and one or more slave databases. The master database is the source of all data, and the slave databases are updated with the latest data from the master database.

* **Peer-to-peer replication:**

In this type of replication, all databases are equal and can act as both master and slave. Data is replicated between databases in a peer-to-peer fashion.

Database replication can be a complex and challenging task, but it can also be a very powerful tool for improving the performance and availability of your database.
