**TLDR:** The data lake layer where source data is first accepted with minimal alteration.

<p>The raw zone is the storage layer in a data lake that sits closest to the source. Data is usually kept here in a form as close to the original as possible, creating a reference point for future processing. Its greatest value lies in recoverability and source fidelity. However, storing raw data is not the same as making it understandable or usable, so it must be designed together with downstream layers.</p>
