Identify the feature of a NoSQL database that allows a large database to be distributed across thousands of servers running the same NoSQL database management system.
a. Deduplication
b. Scalability
c. Integrity
d. Authenticity
b. Scalability
A NoSQL database is highly scalable, meaning that a large database may be distributed across hundreds, thousands, or even tens of thousands of servers running the same NoSQL database management system. This distribution of the database improves system uptime as the database can still process almost all transactions even if a couple of servers are down.
