Final answer:
Non-relational databases that deal with big data are often referred to as NoSQL databases. They are designed to handle large volumes of data, horizontal scalability, and high availability.
Step-by-step explanation:
Non-relational databases that deal with big data are often referred to as NoSQL databases. Unlike SQL databases, which use a fixed schema and structured data, NoSQL databases are schema-less and can handle unstructured and semi-structured data. They are designed to handle large volumes of data, horizontal scalability, and high availability.
One example of a NoSQL database is MongoDB, which stores data in JSON-like documents. Another example is Cassandra, which provides distributed data storage across multiple servers.
NoSQL databases are widely used in big data applications, where massive amounts of data are processed and analyzed in real-time
