Computer Science / Unit 8 CS 0441 short lesson, about 20 seconds
The Data Lake
Captions available
The idea
A data lake stores an enterprise's structured and unstructured data at any scale — raw, no schema defined first — so analytics runs in place against sources never before available.
In practice
A studio's telemetry pours in as-is, questions arriving years later.
Where people slip
The warehouse shapes first, stores second; the lake reverses it.
