Data Pipeline

A data pipeline is an automated, repeatable sequence of steps that moves data from its sources through cleaning and transformation to a final usable form — like an assembly line for data. Each step's output feeds the next, and the whole thing can run on a schedule without a person clicking buttons.

Pipelines turn one-off cleaning into reliable infrastructure: when tomorrow's data arrives, the same code runs again and produces a fresh, consistent result. Good pipelines are monitored and fail loudly, because a silent break upstream can quietly poison every report and model downstream.
