What is ETL in SQL Server?
ETL stands for Extract, Transform, and Load. It refers to a process of integrating data from various sources into a data warehouse or other data repository. ETL SQL is the implementation of this process using SQL (Structured Query Language), a programming language used to manage relational databases.
The Extract step involves gathering data from various sources such as databases, files, or web services. The Transform step involves cleaning, filtering, and transforming the extracted data to make it suitable for analysis or storage. The Load step involves loading the transformed data into a target database or data warehouse.
In ETL SQL, the Extract step can be accomplished using SQL queries to extract data from different sources. The Transform step involves using SQL functions to manipulate and transform the extracted data. Finally, the Load step involves using SQL commands such as INSERT or UPDATE to load the transformed data into the target database or data warehouse.
ETL SQL is a powerful tool for managing and integrating data from multiple sources, making it easier to analyze and make data-driven decisions.
