NoSQL Database


A NoSQL database is a non-relational database that provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. NoSQL databases are designed to handle large volumes of unstructured or semi-structured data, and they provide a flexible schema that allows for easy and fast changes to the data model. NoSQL databases are horizontally scalable, meaning that they can handle large amounts of data by adding more servers to the database cluster. They are also highly available, meaning that they can continue to operate even if some of the servers in the cluster fail. NoSQL databases are commonly used in big data and real-time web applications, where the speed and scalability of the database are critical to the success of the application.
