In a large database with multiple data sources, employing data replication techniques is crucial for ensuring data consistency across all sources. Data replication involves copying and distributing data from one database to another in near real-time, ensuring that updates made to one source are propagated to all other sources. This helps maintain consistency by keeping all data sources synchronized.
