What is NoSQL?

NoSQL is a category of database systems designed to handle unstructured data and provide flexible data models beyond traditional SQL databases. NoSQL stands for "Not Only SQL" or "Non-Relational."

NoSQL databases

NoSQL databases are specifically built for unstructured data storage and retrieval. They are widely used in big data and real-time web applications where data volume and structure can vary unpredictably.

Unstructured data and flexible data models

NoSQL systems excel at handling unstructured data, such as social media posts, multimedia content, and sensor data. They offer flexible data models that can adapt to changing requirements without disrupting the application.

NoSQL categories

There are four main categories of NoSQL databases: document stores, key-value stores, column family stores, and graph databases. Each type is optimized for specific use cases and data structures.

NoSQL technology

NoSQL technology is used by companies like Amazon, Facebook, and Google to store and manage vast amounts of data efficiently. It offers scalability, high availability, and performance advantages over traditional SQL databases in certain scenarios.
