A huge benefit of using joins in Tableau is that we can combine data from multiple tables into a single table for analysis. When those tables are in different databases, it can be a little tricky to work out where to start. If you know how to join tables within the same database, that's great! Cross-database joins only take a few more steps to execute, and I'll walk you through them in today's video.
If you're unsure of how joins work in Tableau, then the best place to start is with the "Joins" section at the beginning of this free webinar and then come back to this video - you'll get more out of it that way around!
