A couple of summers ago, I read a short 577-page book on the dynamics of wealth and income inequality by the French economist Thomas Piketty. This book had kind of become a huge deal in the field of economics. One reason was its huge scope....

A client recently had a challenge wanting to use Exasol’s User-Defined Functions with a Python script, but they were having a hard time coming up with the right syntax to get it working properly. There’s a good deal of documentation out there, though much of...
Portals for Tableau have had the ability to show a sort of live view of the workbooks and dashboards within those workbooks as a part of the navigation for a while now (see this post for more info); however, the portal treated each dashboard as...

Hakuna MaDATA, what a wonderful phrase! It adorned the t-shirts of one of our best partners, Snowflake, at the 2018 Disney Data and Analytics Conference. It’s a fitting slogan not because of the "Lion King" themed event, but because it’s very true of what their...
