The "what is  data pipeline" question arises in cases when it is required to know about the way data is transferred between systems. Data pipeline is a mechanism which receives data from various sources, converts it into a usable form, and transfers it to its destination, which may be, for example, databases or analytics systems. Data pipeline can transfer data from applications, websites, files, and business systems. With such an organization of the process, businesses can avoid manual work and provide themselves with consistent and usable data.
