    - The term replication refers to the operation of copying and maintaining database objects in multiple databases belonging to a distributed system.

    - While replication relies on distributed database technology, database replication offers applications benefits that are not possible within a pure distributed database environment.

    - Most commonly, replication is used to improve local database performance and protect the availability of applications because alternate data access options exist.

    - For example, an application may normally access a local database rather than a remote server to minimize network traffic and achieve maximum performance.

    - Furthermore, the application can continue to function if the local server experiences a failure, but other servers with replicated data remain accessible.
