Description: DISTINCT is a function in DAX (Data Analysis Expressions) that is used to return a single-column table containing the unique values from a specified column. This function is fundamental in data analysis, as it allows analysts and developers to obtain a list of non-duplicate values, facilitating the identification of trends, patterns, and more accurate calculations. The DISTINCT function is particularly useful in contexts where data needs to be cleaned or when analysis depends on the uniqueness of values, such as in the creation of reports or dashboards. When working with large datasets, DISTINCT helps optimize performance by reducing the amount of data processed, which can be crucial in business environments where efficiency is key. In summary, DISTINCT not only simplifies data handling but also enhances the quality of analyses performed on it.
