In database systems, ________ is a technique used to replicate data across multiple nodes to enhance availability and fault tolerance.
- Clustering
- Partitioning
- Replication
- Sharding
Replication involves copying and maintaining identical copies of data across multiple nodes or servers in a database system. It improves availability by ensuring that data remains accessible even if one or more nodes fail. Additionally, replication enhances fault tolerance by providing redundancy, allowing the system to continue functioning even in the face of failures.
