- [Instructor] So starting in Tableau 10,…we now have the ability to create…cross data to joins.…So for this dashboard, we're going to…import our data from two data sources,…the World Bank and UN,…and then merge them together into a single data file.…Cross database joins our powerful tool in linking your data.…The join adds the data right into a single file,…meaning it's easier to do calculations,…table calcs, filters, action, et cetera.…And so we're going to add the data from…the UN and the World Bank…together into a single file.…
