This audiobook is narrated by an AI Voice. A Data Lake is a centralized storage system that allows organizations to store massive amounts of structured, semi-structured, and unstructured data in its raw format. Unlike traditional databases or data warehouses that require data to be processed before storage, a data lake stores information as-is, enabling greater flexibility for analytics, machine learning, and big data processing.
