Are there any good articles out there that speak to the challenges of development in tableau using data blending vs. single source? I have found that development is alot easier when data is in a single source vs. data blending. For example, I had to create 4 worksheets to accomplish something I wanted to do on a dashboard using data blending, whereas I was able to create the exact dashboard using only 2 worksheets when all data was in a single source. I am trying to encourage non-developers who are management that we need to get this data in a single source to make development easier in the future. I need an easy way to explain this to them so was looking for some articles/charts that depict this quandry clearly.
