Data Engineering is the process of building data pipelines and making quality data available for efficient data-driven decision-making.
A person who performs these activities is called a Data Engineer.

But what are data pipelines exactly...
In data processing, there is the flow of data from say a point A to B to C i.e., from an application to a data warehouse or from a data source to the database. This series of processing steps is called a data pipeline.
In these series of steps, each step delivers an output that is the input to the next step. This continues until the pipeline is complete. However, in some cases, independent steps may be run in parallel.

What’s the difference between a data analyst and a data engineer?
Data scientists and data analysts analyze data sets to gain knowledge and insights. Data engineers on the other hand build systems for collecting, validating, and preparing that high-quality data which is then used by data scientists to promote better business decisions.
