Data lake

A vast reservoir of raw data, stored in its natural state like water collected from various streams, ready to be tapped and transformed to quench the thirst for knowledge and insights of those who seek to make sense of the world's information.

Example

A large e-commerce company might use a data lake to store all their customer data, including transaction history, browsing behavior, and product preferences. By pooling this diverse and unprocessed data, the company can then refine and analyze it as needed, gaining insights to improve customer experiences, tailor marketing efforts, and optimize business operations.
