NoSQL Database is a type of database designed to store and manage unstructured or semi-structured data, offering flexibility and scalability compared to traditional relational databases. NoSQL databases often don’t rely on fixed table schemas and are ideal for handling large, complex datasets used in AI and big data applications.
Examples:
- MongoDB: A document-based NoSQL database.
- Redis: A key-value store, often used for caching.
- Cassandra: A wide-column store for high-availability systems.
- Neo4j: A graph database for analysing relationships between data points.
- HBase: A wide-column store built on Hadoop for real-time processing of large datasets.
NoSQL databases are commonly used for real-time analytics, recommendation systems, and storing large-scale unstructured data.
