A NoSQL graph database (standing for “non-SQL” or “Not only SQL” and pronounced “no sequel”) is designed to handle huge sets of structured, semi-structured or unstructured data. A NoSQL graph database can integrate heterogeneous data from a variety of sources and make links between different datasets. It does this by focusing on the relationships between different entities and then surmising new knowledge from information on hand.

The NoSQL graph database is more flexible than a relational database, and also considered more dynamic and less expensive. Its ability to handle massive loads of unstructured data that can come from areas such as the Internet of Things (IoT) is also considered an advantage.
