Which of the following would be used to store unstructured data from different sources?

A data lake is specifically built to store massive amounts of raw data in its native format, including unstructured data like documents, images, and videos, without requiring a predefined schema at the time of ingestion. This allows for flexible storage and later analysis of diverse data types.

A database management system (DBMS) typically manages structured data and often requires a predefined schema, which is not ideal for raw, unstructured data.

A database, in its conventional sense, primarily stores structured data in tables with defined schemas, making it unsuitable for unstructured data without prior processing.

A data warehouse is optimized for storing structured, historical data for analytical purposes, usually after significant transformation and with a predefined schema, making it less suitable for raw unstructured data.
