This document discusses data visualization in Tableau. It covers how to connect to different data sources like databases, files, and public data. It describes generated fields, data extracts, and how to join and blend multiple data sources. The document also discusses factors that affect data connection speed and how to deal with common data quality issues like renaming fields, grouping values, handling nulls, and geographic errors.

20. BLENDING DIFFERENT DATA SOURCES IN A
SINGLE WORKSHEET
 If your data isn’t in one place,blending provides a
viable way to quickly create a left-join-like
connection between your primary and secondary
datasources.
 Blends are more fragile than joins.
 They persist only on the worksheet page on which
they are created.
 Blends offer a different kind of flexibility—the ability
to alter the primary datasource for each worksheet
page

21. HOW TO CREATE DATA BLEND
 Creating data blends requires a little planning. If
you are going to bring data that doesn’t reside in
your primary datasource you have to think about
what field(s) you may need in order to achieve the
desired result.
 There are two ways you can create a blend—the
automatic method or manually defining the blend .

Desktop
