What Is an ETL Pipeline?
ETL, which stands for “Extract, Transform, and Load”, is a course of used to extract information from completely different sources, rework it into an acceptable format, and cargo it right into a goal system (4).
Extract
An ETL program can acquire information from a wide range of sources, together with databases, APIs, information, and extra. The extraction part is separated from the opposite phases to make the transformation and loading phases agnostic to modifications within the information sources, so solely the extraction part must be tailored.
Rework
As soon as the info extraction part is full, the transformation part begins. On this step, the info is reworked to make sure that it’s structured appropriately for its meant use. As a result of information can come from many alternative sources and codecs, it typically must be cleaned, enriched, or normalized to be able to be helpful. For instance, information meant for visualization could require a unique construction to information collected from net types (5). The transformation course of ensures that the info is appropriate for its subsequent stage — whether or not that’s evaluation, reporting, or different functions.
Load
The ultimate part of the ETL course of is loading the reworked information into the goal system, comparable to a database or information warehouse. Throughout this part, the info is written to the goal optimized for question efficiency and retrieval. This ensures that the info is accessible and prepared for functions (e.g., enterprise intelligence, analytics, reporting, and many others.). The effectivity of the loading course of is important as a result of it impacts the supply of knowledge to finish customers. Strategies comparable to indexing and partitioning can be utilized to enhance efficiency and manageability within the goal system.
