ETL stands for Extract, Transform, and Load. It is defined as a Data Integration service that combines data from various sources into a single, consistent data store that is loaded into a Data Warehouse or any other target system. ETL serves as the foundation for Machine Learning and Data Analytics workstreams. Through multiple business rules, ETL organizes and cleanses data in a way that caters to the Business Intelligence needs, like monthly reporting. But ETL is not just limited to this, it can also deal with advanced analytics. This can help improve end-user experiences and back-end processes. ETL is mainly used by an organization to:

  • Extract Data from Multiple Sources
  • Clean the Data to Improve Data Quality and Establish Consistency
  • Load the Data into a Target Database
      

Modern applications need real-time data for processing purposes. So, what is an ETL tool, and what they are? There are numerous ETL Tools available in the market that can simplify the Data Management task while improving Data Warehousing. These tools can help you save valuable time, effort, and money.
