Speed Curve
DECEMBER 11, 2019
I confess, I’m not a statistician. While I pride myself on the 'A' I received in my college statistics class, admittedly it was on a pretty steep curve. That said, I’ve been looking at performance data for many years and have found myself on both sides of the debate about whether or not the practice of sampling performance data is inherently a good or bad idea.

The closer you look at something, the more interesting it gets. That’s probably why I love it when I’m able to pore through large amounts of data related to a topic that interests me. You keep twisting and turning it enough, and you’ll eventually start to uncover fascinating trends and insights that weren’t apparent on the surface. Hence, why I’m a big fan of BigQuery.

NULL handling is one of the trickier aspects of data modeling and data manipulation with SQL. Let's start with the fact that an attempt to explain exactly what a NULL is is not trivial in and of itself. Even among people who do have a good grasp of relational theory and SQL, you will hear very strong opinions both in favor and against using NULLs in your database.
