Data Lake
Definition
A data lake is a centralized repository that stores raw, unprocessed data in its native format — structured, semi-structured, and unstructured — at any scale. Unlike a data warehouse, a data lake imposes no schema at write time (schema-on-read).
Platforms like AWS S3 with Athena, Delta Lake, and Apache Iceberg are common data lake implementations. Data lakes enable flexible analytics and ML on heterogeneous data.

Every CISO is asking these three questions. We answer them with facts, not guesses, from repository to runtime.
