140+ NoSQL MCQ With Online Practice Test
NoSQL, short for "Not Only SQL," represents a family of database management systems designed for flexible and scalable data storage. Unlike traditional relational databases, NoSQL databases employ various data models like document, key-value, graph, and column-family, enabling them to handle diverse data types and structures. NoSQL databases are well-suited for applications requiring high data velocity and volume, such as web and mobile apps, IoT devices, and big data analytics. They offer horizontal scalability, strong performance, and support for distributed, non-tabular data storage, making them a valuable choice for modern, dynamic data management needs.
