Non-relational Database

A non-relational database is a database that does not use a tabular schema of rows and columns. Instead, it uses a storage model that is optimized for the specific type of data being stored. For example, data may be stored as a key/value pair, as JSON, or as a graph consisting of nodes and edges.
