What is transformation?

Transformation, in a general computing context, refers to altering the format, structure, or content of data. This can involve converting data from one format to another (e.g., XML to JSON), reshaping data to fit a specific schema, or modifying the data's values. Transformation is crucial in data warehousing, data integration, and ETL (Extract, Transform, Load) processes, enabling data from disparate sources to be combined and analyzed effectively. It is also widely used in data manipulation and processing tasks across various applications, including data cleaning, data enrichment, and data preparation for machine learning.
