What is a data pipeline?
A series of steps that moves data from a source to a destination, cleaning and transforming it on the way. Like a water pipe — raw input goes in, treated output comes out, and you can trust what arrives.
A data pipeline is a sequence of steps that move data from one place to another, transforming it along the way. Think of it like a real-world pipeline that carries water from a reservoir to your house. Along the way, the water gets filtered, treated, and pressurized so it arrives clean and usable.
In Data Engineering, the same idea applies to data. Raw data comes in from sources (APIs, databases, files), goes through cleaning and transformation, and lands in a destination where analysts and applications can use it. Building reliable pipelines is the core job of a Data Engineer.
