ETL tools provide a graphic user interface that allows users to easily visualize the system logic and set up rules using a drag and drop interface.
It will specify data sources and rules for extracting and processing data after implementing it, eliminating the need to do traditional coding and writing procedures.
What is ETL? This tool simplifies moving large data volumes and assists users with calculations, strings manipulation, changes, and data integration.
Build a high-quality data warehouse with the use of an ETL platform with performance-enhancing technologies.
The main steps in the ETL process are:
ETL can handle a variety of data sources, including relational databases, flat files (like CSV or Excel), APIs, cloud storage, and more.
Common ETL tools include Apache Nifi, Talend, Informatica PowerCenter, Microsoft SQL Server Integration Services (SSIS), and Apache Airflow, among others.
Challenges in ETL can include handling large volumes of data, ensuring data quality and consistency, managing data from disparate sources, and maintaining performance and scalability during data processing.
