While learning about cloud technologies and their potential Damiana kept hearing about the importance of data analysis and how Tableau was changing this field. After realising how data analysis was changing every field, Damiana eagerly jumped at the chance to learn everything about how to do it best with Tableau.
In her spare time Damiana likes doing yoga, burning time on her PS4 and learning new languages. She’s currently mastering Danish!

Today's topic might not necessarily be best practice in terms of visualisation, but scores really high on the prettiness / quirkiness scale. I will show you how to replace your bars with... other bars, except that they will be made of little shapes 🙂 After we'll be...read more
Third day of the Data School Week Tip. In the last post I have talked about how to use sets across data sources. Today I will talk about different data sources again, but this time it's about filtering more than one data source using parameters. It's a neat little...read more
