Why are NoSQL databases often used for very large unstructured datasets?

NoSQL databases are often used for very large, unstructured datasets because they do not require the fixed, tabular structure—consisting of rows and columns—that defines traditional relational databases.12

While traditional databases rely on SQL to manage structured data, this language is often not the most effective tool for handling qualitative and unstructured information, such as video, audio, or text. NoSQL (non-relational) databases provide the flexibility to store these diverse data types without the constraints of a rigid schema. Many of these systems are document-oriented, allowing for the storage of varied media alongside traditional text, which makes them highly suitable for the demands of modern big data applications.12
