NoSQL

NoSQL refers to a category of database systems that are designed to handle a wide variety of unstructured and semi-structured data. Unlike traditional relational databases that use structured query language (SQL) and follow a table-based schema, NoSQL databases offer flexible data models, which allow them to store and manage data in formats such as key-value pairs, documents, columns, or graphs. This flexibility makes NoSQL particularly well-suited for applications that require rapid scalability and can handle diverse types of data, including text, images, and videos, which do not fit neatly into tables. In addition to their schema flexibility, NoSQL databases often provide high performance and scalability, making them ideal for handling large volumes of data and high-velocity workloads. They are commonly used in big data applications, real-time web apps, and content management systems where traditional relational databases may struggle to meet performance demands. With their ability to distribute data across multiple servers, NoSQL databases help ensure reliability and fault tolerance, making them a popular choice for modern, data-driven applications.
