Q: 1Which of the following represents the two approaches to store a relation in the distributed database?
Option A
In a distributed database system, data is stored across multiple sites or nodes, and there are two main approaches to store relations.
Replication involves storing copies of the same data at multiple sites to increase availability and allow parallel query processing. However, replication requires synchronizing updates across copies to maintain consistency, which adds overhead.
Fragmentation involves dividing a relation into smaller parts called fragments, and storing each fragment at a site where it is most needed.
