Which storage method is most suitable for managing large-scale unstructured data like videos or social media posts?

Document-based NoSQL databases like MongoDB or Couchbase are ideal for handling large-scale unstructured data. They support flexible schemas and can store various data formats, such as JSON or XML, making them highly suitable for videos, images, and social media posts. They also offer horizontal scaling, ensuring efficiency with increasing data volumes. Why Other Options Are Wrong : A) Relational databases are better for structured data but struggle with unstructured data. C) Flat files are inefficient for managing and querying large-scale datasets. D) Graph databases focus on relationships between entities, unsuitable for unstructured media data. E) In-memory databases are fast but lack scalability for large datasets.
