Do you know how DATES work in Tableau? Understanding Continuous vs Discrete Dates

Do you know how dates work in Tableau? It could be tricky, but once you get a handle on it, it can make your Tableau life much simpler.

The first step to understanding dates in Tableau is understanding the concept of discrete and continuous first. These are two very important concepts in Tableau that, if not clearly understood, can definitely cause a lot of confusion (and headaches). It can make you think you’re getting unexpected vizzes or behavior from the application, and that it’s not doing what it’s supposed to do.

A quick Google search lands us the definitions for these two terms:

discrete – individually separate and distinct
continuous – forming an unbroken whole; without interruption

Let’s tie these two terms back to Tableau:

Data Sets for BI/Analytics/Visualization Projects

Just wanted to compile a list of datasets, or sources of datasets, that can be used for BI/Analytics/Visualization projects and explorations (not limited or specific to any tools). These come in different formats, and some may need to be cleaned up. Please do read the restrictions and EULAs that come with each of the links/sources.

This is a work in progress. I  am still updating this post, and will most likely re-arrange or re-categorize the links as I stumble across other data sets.

If you have any that you can share, I would love to add those to this list (and mention you shared it!) – please leave a comment below and I will add them to the list!

By the way, Microsoft has switched to Pearson as a testing provider. You may find that testing centres could be scarce in some locations at first, hopefully that picks up soon!
