As a recent convert from Power BI, the video segment on relationships was invaluable! I finally had an "Oh, I get it!" moment. My mind started seeing what I had been familiar with in Power BI, but in Tableau language. Thank you so much! Love the videos! I might have to get your advice at the end framed and hung in my office. :)

I share the sentiment. This is exactly the Aha moment of tableau

Wow, what a superb explanation. This is just what i was looking for. When i started with tableau, I always happen to find duplicates when i have different data sources, so my always go to action was to fix duplicates at database level, create a view / table and use it as a single table , for this i need data engineers to move all my data sources into one database( could be Redshift or snowflake) which took a lot of time, now by using relationships , i can use them on the go without any issues. Secondly, i can answer different business questions by changing my primary and secondary table in the data viz itself, No need to go back to data source.

Quite informative video. We understand that blending is useful to play with data from different data sources. However the cross data base Joins or Relationships can solve the purpose but comes with a few limitations.

Thank you Tanya! I don't think there's an easy button though to convert from blending to relationships because it works different ways (for example, you will need one data source instead of multiple). You may need to re-create some of them, but it might be a good thing as it can also allow you to take advantage of other newer features in Tableau.

Thanks Jiangzheng, that's a great question. If the conditions are more than just simple conditions, I am inclined to recommend doing a "cleaning phase" first before connecting them in Tableau, if possible. For example, you can use some ETL tools on the database side, or for example client tools like Tableau Prep or Power BI.

Wow… this is really nice. It helps a lot. Can you provide same datasets (3 excels) which you being used in this tutorial is really appreciated.

Thanks. Have you dived deep into relationships? So e.g. why does it matter which table you first drag into Tableau when setting up your "relationship" model? What if there are multiple fact tables and you need to have the same dimension tables twice in your model? Have you experienced any strange behavior so far? Would highly appreciate more on this as the documentation and videos (at least I found so far) are not addressing these question in detail enough for me. best regards and take care

Thank you for your note Daniel, and these are great points. I am not able to address some of the why's of Tableau as I am not privy to those, but I can understand why they may have chosen to go this route. Perhaps there are different ways to tackle this. In my projects I would handle drill across in fact tables using multiple views from the database end. I would be wary of having a different tool automatically handle this especially if the dimensions are used in different kinds of fact tables (transactional vs periodic for example). I would opt to do the joins within the database itself and expose as a view for Tableau because it provides more control, and will allow me to address nuances of my specific datasets outside of Tableau. I will take advantage of Tableau's features like Joins, Blends, Relationships on smaller data sets, but wherever I can I would data cleaning and modeling to the data source. Often my data sources are powerful/resource-heavy enough to handle the cleaning/modeling with more ease than Tableau. I am not sure if this is helpful, but just wanted to share with my own thoughts and strategies.

Enlightened :)

@sqlbell. For practice purposes is possible to attach the exact data sets you use for each video?

Omg finally a good, really well done example of why relationships are so important in terms of making analytics more accessible. Follow up question on your parting advice. How do we create relationships between published data sources? So let’s say, I have customers and orders and products all nicely related and I publish the extract to be refreshed daily. My colleague is analyzing delivery estimates which are a function of order total and customer membership tier. They don’t want to also create the same relationships that I already setup, and they just went to add some more to it… is blending just the best option in that scenario?

excellent

This is a awesome video. Could you please let me know like how to handle Measures while using relationships.

It will be great for me if you can share few tips related to this.

Hello Aditya - do you mean to pull all related fields automatically? No this option does not exist at this point in Tableau.

Hi Belle, Is it possible to share the Excel, I wanted to test use case at 17.10, what if I want to add product ID and next to it the Salary earned by Customers? To know, what is the range of salaries of customers who are buying particular products. I believe the tableau will again do a sum(salary) if I have a customer buying a product more than once. In this case, can we use again FIXED LOD?
