NoSQL is a catch-all term for a variety of database types that exhibit common architectural approaches. These databases aren’t intended for related table, rows, and columns data. They are highly distributed, which means data is spread across several servers, and they’re tolerant of data structure changes (that is, they’re schema agnostic).
