NoSQL Databases

NoSQL databases are non-relational data storage systems designed to handle large volumes of unstructured or semi-structured data with flexible schemas. They prioritize scalability, performance, and availability over strict ACID compliance, often using distributed architectures. Common types include document, key-value, graph, and column-family databases.

Also known as: No Config Databases, Non-relational Databases, NoSQL DB, NoSQL, Not Only SQL

Why learn NoSQL Databases?

Developers should use NoSQL databases when building applications requiring high scalability for big data, real-time web apps, or handling diverse data formats like JSON. They are ideal for use cases such as social media platforms, IoT systems, and content management where schema flexibility and horizontal scaling are critical, unlike traditional relational databases.
