What is the function of a "data pipeline" in data engineering?

A data pipeline is fundamentally designed to transport data from one system to another. This involves the processes and tools that move and transform data from its source, often through various stages of processing, until it reaches its destination, such as a data warehouse or analytics platform. The primary role of a data pipeline is to ensure a seamless and efficient flow of data, which is crucial for maintaining data integrity and timeliness in analytics and reporting.

While collecting and visualizing data, providing storage solutions, and enforcing data security are important aspects of data engineering, they do not encapsulate the main purpose of a data pipeline. Collecting data is typically the initial step that feeds into a pipeline, visualization occurs after data has been processed and transported, storage solutions are necessary to house the data being moved, and security policies relate to protecting data rather than the transportation itself. Thus, the essence of what a data pipeline does is to facilitate the movement of data across different systems, ensuring it is available for use in a timely and organized manner.
