NoSQL Tutorial

NoSQL is a non-relational database system designed to store and manage large volumes of structured, semi-structured and unstructured data. It provides flexible schemas, high scalability and fast performance for modern data-driven applications. NoSQL databases are widely used in cloud computing, big data, real-time systems, IoT platforms and social media applications.

• Supports flexible and schema-less data models
• Provides horizontal scalability for large-scale applications
• Handles high-speed and high-volume data efficiently
• Includes databases like MongoDB, Cassandra, Redis and Neo4j
