Solution
The best description for a NoSQL database is "Non-relational and schema-free".
NoSQL databases are non-relational, meaning they do not rely on the traditional row-and-column schema that relational databases use. They are also schema-free, which means they do not require a fixed schema and allow the data to be stored in many ways such as key-value, document, columnar and graph formats. This flexibility allows for high performance, high availability, and easy scalability.
