What is ETL?

ETL (or extract, alteration and load) is simply a much circumstantial mode to grip data. Not to beryllium mistaken for ELT (extract, load, transform), ETL is simply a process wherever information is extracted from aggregate sources, transformed into a standardized format and loaded into a destination system. Here’s a person look astatine the 3 phases:

1. Extract: The extract signifier involves taking information from its sources, requiring you to enactment with some structured and unstructured data.
2. Transform: Transforming information involves changing it into a high-quality, reliable format that aligns with a company’s reporting requirements and intended usage cases, which whitethorn impact correcting inconsistencies, adding missing values, excluding oregon discarding duplicate information and completing different tasks to summation information quality.
3. Load: Loading information means moving it to its people location, specified arsenic a data warehouse repository that holds structured information oregon a data lake that accommodates some structured and unstructured data.

ETL is an end-to-end process that allows companies to hole datasets for further usage.
