Introduction I recently realized that I created a lot of Tableau and Alteryx content over the past 8 months. Sometimes I need to reference the material and it can be hard for me to find. I figure that if it is hard for me to find, others will have no chance of finding it.
Introduction For four months (October 2013 to January 2014) I did a job that was tough. It was tedious, time consuming, and it caused Tableau to buckle under the pressure of multiple data sources, multiple data joins, and difficulties with data formats.
