Description: A transformation table is a fundamental tool in data processing environments that allows users to define how data should be transformed from one format to another. This table acts as a map that guides the transformation process, facilitating the manipulation and analysis of data from various sources. Through this table, users can specify rules and criteria that determine how data should be modified, such as converting data types, creating new columns, removing duplicates, or grouping information. Transformation tables are especially useful in environments where data is heterogeneous and requires specific treatment to be effectively analyzed. Additionally, they allow data analysts to maintain the integrity and quality of information, ensuring that the results obtained are accurate and relevant. In summary, the transformation table is a key piece in the data preparation process, as it optimizes how data is managed and visualized, improving decision-making based on analytical information.
