👉 A data lake is a centralized storage system that allows organizations to store vast amounts of structured, semi-structured, and unstructured data in its raw, unprocessed form. Unlike traditional databases or data warehouses, which typically require data to be pre-processed and structured before storage, a data lake preserves the data in its native format, providing a scalable and flexible solution for data management.
Example: In a data lake, raw data from sensors, customer interactions, and transaction logs can be stored and analyzed together, enabling comprehensive insights and advanced analytics without pre-defined schema constraints.
