NoSQL Databases

NoSQL databases are a category of database management systems that do not use the traditional relational model. They are designed to handle large volumes of unstructured or semi-structured data, offering flexibility and scalability. Common characteristics include schema-less data storage, horizontal scalability, and support for various data models such as document, key-value, graph, and column-family. NoSQL databases are widely used in big data applications, real-time web apps, and for storing data in cloud environments, making them suitable for scenarios where traditional SQL databases may struggle.
