Q: In a distributed database, what is the purpose of data replication?
Solution: Data replication in a distributed database ensures data consistency across all nodes by maintaining copies of the same data in multiple locations.
Steps: 5
Step 1: Understand that a distributed database is a database that is spread across multiple locations or servers.
Step 2: Know that data replication means making copies of the same data in different places.
Step 3: Realize that the purpose of data replication is to keep the data the same (consistent) everywhere it is stored.
Step 4: Recognize that if one server has a problem, other servers with the same data can still provide access to that data.
Step 5: Remember that data replication helps improve performance by allowing users to access data from the nearest location.
