    Connectind to Data: Union vs Copy and Paste

    Enrico Serafini

      Hello everyone!

       

      I am new to Tableau and I am wondering what is the best strategy I should follow to connect to my datasets.

       

      I have one main dataset that will be updated with thousands of new rows monthly. I will have to download the additional rows on a new dataset every month.

       

      I think I have 2 possible strategies ahead::

      1. I use a Union connection with the new dataset that I will download monthly;

      2. I simply copy and paste (monthly) the additional rows to the original dataset.

       

      Which strategy is the best way to follow?

       

      I noticed that with Unions my workbook got much slower, but at the same time it would make to process more automatic.

       

      Thank for your time,

      Enrico
