Chapter 3. All about Data – Joins, Blends, and Data Structures

Connecting Tableau to data often means more than connecting to a single table in a single data source. You may need to use Tableau to join multiple tables from a single data source. As of Tableau 10, you can also join tables from disparate data sources. Sometimes, you may need to merge data that does not share a common row-level key. In such cases, you will need to blend the data. Also, you may find instances where it is necessary to create multiple connections to a single data source in order to pivot the data in different ways. This may be required in order to discover answers to questions that are difficult or simply not possible to address with a single data structure.

In this chapter, we will discuss the following:

Complex joins
Data blending
Data structures

Baldwin

Ryan Baldwin is a theatre major turned computer science geek. Hailing from the prairies of Western Canada, Ryan has been developing software on a wide array of platforms and technologies since 2001. Once, he wrote a crazy system application that compiled XSD Schema Docs into XAML forms that performed two-way binding with underlying XML documents in .NET WPF. Why? Because it had to be done. Another time, he worked on a project that would mash multiple social networks together, allowing users to find out who they were indirectly "connected" to (something akin to 6 Degrees of Kevin Bacon). It was eventually shelved. In 2012, he relocated to Toronto, where he works with the University Health Network, developing systems and tools that facilitate patient information exchange. You can often find him wearing headphones and jittering in coffee shops.
