Which database technology is often used for distributed data storage and retrieval in big data scenarios?
- In-memory databases
- NoSQL databases
- Object-oriented databases
- Relational databases
NoSQL databases are often used for distributed data storage and retrieval in big data scenarios. Unlike traditional relational databases, NoSQL databases are designed to handle large volumes of unstructured or semi-structured data across distributed systems. They offer flexible data models, horizontal scalability, and high availability, making them well-suited for handling the complexities of big data environments. Examples of NoSQL databases include MongoDB, Cassandra, and HBase.
