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. It 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.
