NoSQL Databases

NoSQL databases are non-relational databases that store and retrieve data using methods other than the traditional tabular relations used in relational databases. NoSQL databases are designed to handle large volumes of unstructured or semi-structured data, making them ideal for big data and real-time web applications. NoSQL databases are horizontally scalable, meaning that they can handle large amounts of data by adding more servers to the database cluster. NoSQL databases are also highly available, meaning that they can continue to operate even if one or more servers in the cluster fail. NoSQL databases use a variety of data models, including document, key-value, column-family, and graph. Each data model is optimized for a specific type of data and use case.
