The correct exploitation of the data goes through its cleaning and prior transformation by processes called ETL (Extract-Transform-Load) which, due to their importance, represent a significant percentage of the development time of a report. Tableau Prep builder allows connection to our data sources and the creation of versatile "flows" that determine the transformations to be applied to the data. In this course we will learn how to create and configure these flows to be able to read the transformed data from Tableau and be able to design, in this way, reports based on data with the appropriate quality.
