Description: A transformation tool is software designed to modify, clean, and structure data during the ETL (Extract, Transform, Load) process. Its primary function is to ensure that data extracted from various sources is converted into an appropriate and consistent format before being loaded into a storage system, such as a data warehouse. These tools allow for complex operations, such as data normalization, duplicate removal, type conversion, and the application of business rules. Additionally, they facilitate the integration of data from different sources, ensuring that the information is accurate and useful for subsequent analysis. Transformation tools are essential in the context of business intelligence, as they help organizations gain valuable insights from large volumes of data. Their relevance has grown with the rise of big data and the need for real-time analysis, becoming a critical component in modern data architecture.
