What is a key characteristic of NoSQL databases?

NoSQL databases are designed to handle a variety of data types, including unstructured data. Unlike traditional relational databases that require a fixed schema to define data structure and relationships, NoSQL databases offer greater flexibility by allowing data to be stored without a predefined schema. This capability makes them particularly well-suited for applications that manage large volumes of diverse data, such as social media, big data analytics, IoT applications, and more. The ability to accommodate unstructured data—such as text, images, or videos—enables organizations to efficiently store and retrieve information in formats that better reflect real-world data complexity.

This characteristic positions NoSQL databases as a vital component in the modern data ecosystem, particularly when rapid development cycles and scalability are required.
