This chapter was short but the three new features presented will undoubtedly be useful for you! With cross-database Join, you can create a unique Data Source that combines multiple different connections. With data-blending, you can create a relationship between multiple Data Sources to use their fields in the same Worksheet. Finally, you learned how to give superpowers to Unions thanks to Wildcard Unions, a feature that automatically adds files and tables based on a pattern.

We have one last technical chapter to go, and it's not a trivial one, as we'll talk about security. You will see how to secure your data on Tableau Server and in Tableau Desktop, thanks to three different layers of protection. What are you waiting for? You're almost at the end!
