NoSQL

Non-relational database architecture (Not Only SQL) designed for massive horizontal scaling and flexible, schema-less data models.

NoSQL represents a diverse category of non-relational database systems (Not Only SQL) built to handle modern application demands: massive data volume, high velocity, and schema flexibility. Unlike rigid SQL databases, NoSQL leverages four core models: Key-Value (Redis), Document (MongoDB), Wide-Column (Apache Cassandra), and Graph (Neo4j). This distributed architecture enables superior horizontal scaling and high availability across commodity servers. It is the primary choice for big data, real-time web applications, and large-scale platforms like Netflix and LinkedIn, where agility and performance outweigh strict transactional consistency.
