What is NoSQL Database?

Non-tabular databases, such as NoSQL databases, store data in a different way than relational tables. NoSQL databases are classified according to their data model. Document, key-value, wide-column, and graph are the most common types. They have adaptable schemas and can handle big amounts of data and high user loads with ease.
