How is data stored in a NoSQL database?
What will be an ideal response?
A NoSQL database stores data as highly optimized key-value pairs with the data stored in a simple two-column table, one column reserved for a unique record identifier (e.g., customer id) and the other for the data value. 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.
